Evaluation of the Force Sensitive Application hand force measurement system
Authors: Jung Kihyo , You Heecheon , Kwon Ochae 
Published: August 2010

AbstractThe Force Sensitive Application (FSA) system is used to measure forces exerted by the hand on an object. The present study evaluated the FSA system in terms of stability, repeatability, accuracy, and linearity at the sensor and system (pulp press, pulp pinch, and power grip) levels. At the sensor level, the FSA sensor showed high performance in stability (coefficient of variation [CV] ≤2%) and linearity (coefficient of determination [R2] = 0.95), but low performance in repeatability (CV = 11∼19%) and accuracy (14∼26% overvaluation). At the system level, the FSA system showed a decreasing accuracy (12∼30% undervaluation) as the number of sensors involved in the test increased, but retained a high linearity (R2 = 0.95∼0.98) to measurement from a dynamometer. These evaluation results indicate that the FSA system should be used for relative, not absolute, comparison in force evaluation due to its lack of accuracy and that the accuracy of the FSA system can be improved due to its good linearity by calibrating FSA measurements with a dynamometer having a high level of accuracy. © 2010 Wiley Periodicals, Inc.
A comparison of multivariate statistical methods for estimating expected consequences for low‐probability and high‐consequence incidents
Authors: Desai S. , Lim G. J. , Karson M. 
Published: August 2010

AbstractThe catastrophic incidents involving hazardous materials (hazmats) have often been termed as low probability and high consequence (LPHC). The purpose of this article is to address some fundamental questions with regard to hazmats incidents: What is the expected consequence of a hazmats incident? How should the consequences of incidents involving hazmats be predicted? An exhaustive statistical analysis is performed on the hazmat incident data available from the U.S. Hazardous Materials Incident Reporting System (HMIRS). We present a sequence of logically deduced, linear statistical models to estimate the two major areas of impact of an incident: (1) population affected and (2) cost incurred due to an incident based on the outcomes of the incident. Our initial experiments indicated that linear models are not sufficient for predicting the consequences. Subsequently, we extended our work to evaluate the effectiveness of three multivariate statistical methods, namely (1) partial least squares, (2) spline regression, and (3) Box‐Cox transformations. Based on our experiments, Box‐Cox transformation showed significant improvement in estimating the consequences. Last, we summarize our findings and provide some general guidelines to entities interested in estimating events categorized as LPHC. © 2010 Wiley Periodicals, Inc.
Mixed Ca/Zn thermal stabilizers for weatherable rigid PVC
Authors: Mur G. , Madgwick R. 
Published: August 2010

AbstractRigid PVC profiles for window frames are required to follow quality standards (usage properties and aging resistance). Our concern is to describe the role of additives and mainly thermal stabilizers on the required properties. Until recently, PVC stabilization was based on heavy metal soaps in the European PVC building industry. Though their resulting efficiency was not questioned, problems of toxicity were raised. Regarding the ecological pressure increase, numerous investigations on co‐stabilizers have been carried out in order to improve the performances of mixed Ca/Zn systems. Our results show the properties of rigid profiles stabilized with Ca/Zn systems. First, the extruded profiles properties such as optical (color) and mechanical properties (impact resistance…) are shown. The aging resistance of toxic heavy metal free vinyl formulations is also studied in comparison with typical Pb/Ba/Cd. The performances achieved indicate that an opportunity to move from toxic heavy metallic stabilizers to mixed Ca/Zn systems, resulting, perhaps, in wider development of Ca/Zn stabilizing systems for food packaging and medical plastics.
Typical flame retardant/additive chemicals for commercial FR‐HIPS and FR‐ABS resins
Authors: Song Jim H. 
Published: August 2010

AbstractThis paper makes an overall review on performance, cost, compoundability, and environmental compatibility of flame retardant chemicals used for commercial flame retardant impact polystyrene (FR‐HIPS) and flame retardant acrylonitrile‐butadiene‐styrene (FR‐ABS) resins. Commercially available, key bromine and chlorine chemicals along with antimony oxide are discussed with the typical formulations focusing on the overall advantage(s) and weakness(es) of each chemical.
Volatiles from thermal degradation of PVC compounds
Authors: Bautista Paul A. 
Published: August 2010

AbstractSeveral methods were developed to measure and identify the volatile species generated when PVC is heated to decomposition temperatures. PVC film compound containing various organotin stabilizers was processed under a range of typical conditions. The film samples were subjected to degradation temperatures of 210 to 230°C in both enclosed sampling systems (for optimum collection efficiency) and open systems that were designed to mimic working conditions. The collected samples were analyzed for amounts of hydrogen chloride, organotin compounds and organics in general. Variables such as type of stabilizer, degradation time and temperature, and sample thickness and fusion time were studied.
Rheological properties of poly(vinyl chloride) / epoxidized natural rubber blends. Part II: The effect of processing variables
Authors: Ishiaku U. S. , Nasir M. , Ishak Z. A. Mohd 
Published: August 2010

AbstractThe effect of processing variables on the rheological properties of PVC/ENR blends was investigated. The role of crosslinking in determining the flow behavior of blends was also examined by means of dynamically cured blends. It was found that PVC/ENR blends yield melts that are power law fluids. The flow of the melts improves with an increase in temperature and shear rate. However, the introduction of crosslinks reverses this trend, although under more rigorous conditions, the influence of crosslinks is superseded, and subsequently, flow becomes shear rate and temperature dependent. PVC/ENR systems also manifested elastic phenomena. The dependence of the elastic phenomena such as die swell and melt fracture on L/D ratio of the die was demonstrated.
Analysis of rigid PVC‐styrenic copolymer blend systems
Authors: D'Souza Nandika Anne , Letton Alan , Asay R. Elliott 
Published: August 2010

AbstractIn an effort to improve the utility and processing of PVC, additives like heat distortion modifiers and plasticizers are often added. While the economics of using PVC are highly favorable, they are limited in their dimensional stability at high temperatures. Blending with a component having better dimensional stability at higher temperatures is therefore investigated. In this paper, use of a styrenic copolymer, styrene acrylonitrile (SAN), and a substituted styrenic copolymer, alpha methyl styrene acrylonitrile (αMSAN), is studied. The glass transition‐composition behavior is studied through dynamic mechanical measurements. Heat distortion test results of the blend in compositions of 0–100 in 10% increments indicate enhanced DTUL above certain compositions. Rheological characterization is done both in the low strain steady shear and dynamic mode. High shear rate testing was done. In general it was found that while the styrenic copolymer exhibits a plasticization of the PVC glass transition, the substituted styrene, by maximizing the repulsive interaction effects, pushes the system to a limited partial miscibility.
The performance of sulfonate salt‐containing polycarbonate products in flammability testing
Authors: Morgan Sarah , Davis Gary , Gijzen Erwin , Lemmen T. 
Published: August 2010

AbstractSulfonate salts are commonly employed together with other standard flame retardant (FR) additives to improve FR performance in polycarbonate resins. The structure and loading level of the salt and the synergistic FR additives determine the level of FR performance. The salts show varying levels of FR effetiveness as measured by different flammability test methods. In this paper, two common sulfonate salt additives in Lexan polycarbonate resins are discussed. FR effectiveness measured by UL94, OSU and cone calorimeter flammability testing, physical and mechanical properties, and processability of the thermoplastic products are compared. TGA‐IR studies and the ability to predict FR performance are also discussed.
Modeling of single‐screw extruders with mixing pins: The case of PVC
Authors: Thibault F. , Tanguy P. A. , Blouin D. , Hurez P. 
Published: August 2010

AbstractA computer model is proposed to simulate the flow of molten polymer in the melt conveying zone of extruders provided with mixing pins. This model is based on the calculation of down‐channel velocities within cross sections perpendicular to the flow. A Lagrangian reference frame (i.e. that of the barrel sliding on top of the channel) is used to describe the flow in a convenient manner, the mixing pins being represented as a set of virtual boundary conditions (geometric constraints). The proposed method is compared to a full 3D finite element flow simulation with Newtonian and non‐Newtonian fluids showing a good agreement in term of the pressure drop calculation. Numerical tests are also carried out in the case of a rigid PVC compound used for window profile extrusion. The adequacy found between the predictions and experimental measurements obtained on an industrial extruder confirms the performance of the proposed model.
Rheological properties of poly(vinyl chloride)/epoxidized natural rubber blends. Part I: Composition dependence and the effect of compounding conditions
Authors: Ishiaku U. S. , Nasir M. , Ishak Z. A. Mohd 
Published: August 2010

AbstractEpoxidized natural rubber is a recently commercialized modified form of natural rubber. This paper is part of our continuing effort to study the responses of this new material to melt mixing and other shaping processes. The Shimadzu capillary rheometer was used to evaluate the composition dependence of miscibility of polyvinyl chloride/epoxidized natural rubber blends (PVC/ENR blends). The rheometer was also used to evaluate the effect of compounding parameters on the rheological properties of the blends. The results confirmed PVC/ENR blends as miscible systems that show a synergism in apparent shear viscosity highlighted by the positive deviation from the logarithmic additivity rule. These results based on capillary rheometry are also in very good agreement with our earlier attempt to predict optimum mixing from torque rheometry by using the Brabender Plastogram as an indicator.
Smoke reduction for flexible PVC‐high surface area: Alumina trihydrate vs. magnesium hydroxide
Authors: Molesky Frank , Schultz Robert , Midgett Sam , Green Don 
Published: August 2010

AbstractThis paper reviews three flexible PVC formulations using various types of alumina trihydrate (ATH) and magnesium hydroxide [Mg(OH)2]. Smoke values are compared. In two of the formulations, Mg(OH)2 has better smoke values than ATH; in a third formulation, ATH has better smoke values than Mg(OH)2. However, the third formulation uses an ATH with a very high surface area, which may indicate that smoke suppression may be a function of not only the type of flame retardants used but also surface area.
Evaluation of the lubricant properties of candelilla wax in unplasticized PVC/wax systems
Authors: Angulo‐Sanchez J. L. , Valverde‐Herrera V. 
Published: August 2010

AbstractThis paper reports on the evaluation of a natural product, candelilla wax, as a possible lubricant for unplasticized PVC formulations stabilized with lead or barium/cadmium chemicals. The lubricant effect of two types of wax (commercial grade and purified by solvent extraction) was evaluated by torque and extrusion rheometry and by differential scanning calorimetry. Commercial lubricants (Loxiol) were used for comparison. The results show that candelilla wax may be used as a lubricant (mainly of the external type) for unplasticized PVC; however, care must be taken when designing formulations to avoid over‐lubrication, specially when lead‐based thermal stabilizers are used.
UV‐cured pultrusion processing of glass‐reinforced polymer composites
Authors: Kennedy Kenneth C. , Kusy Robert P. 
Published: August 2010

AbstractA novel process was developed to adapt the pultrusion process to utilize radiation polymerization instead of thermal curing. Using UV‐light and a methacrylate‐based, 3‐D‐network copolymer matrix, 0.5 mm diameter round quartz‐fiber‐reinforced‐composite profiles were formed at a rate of 1.25 mm per second. Faster rates resulted in partial curing. Materials were produced with various amounts of reinforcement, and evaluated in tension and in three‐point bending. Mechanical properties varied linearly with fiber content, approaching the rule of mixtures.
Structure‐property relationships of short fiber reinforced polypropylene‐polyamide blends
Authors: Silberman A. , Weiner F. , Kenig S. 
Published: August 2010

AbstractShort fiber composites based on polypropylene (PP)‐polyamide (PA) blends were studied using compatibilizers comprising maleic anhydride modified polypropylene. Results have shown that the structure and morphology developed and the resultant mechanical properties of the blend composites strongly depend on the number of acid functional groups in the compatibilizers. The impact strength and tensile modulus of the PP‐PA blend composite more than doubled compared with PA and PP short fiber composites, respectively. Furthermore, analytical methods characterizing nonisothermal crystallization were used to investigate the crystallization of fiber containing blends in constrained matrix nucleation mode. Results have shown that interphase interactions are the dominant ones with respect to morphology development. Synergistic effects were obtained that were due to the effect of fibers.
