Polyethylene is a lightweight thermoplastic. It is often abbreviated to LDPE (low density polyethylene) or HDPE (high density polyethylene). Bonding polyethylene is considered very difficult and as a result it is often used as packaging for adhesive materials – as the glue won’t stick to it! It is a widely used and popular material for items such as packaging, storage containers, chemical drums, tanks and many other low-cost assemblies. The material itself is not particularly high performance and will deform and melt at high temperatures and be easily attacked by solvents. This makes solvent welding, ultrasonic or infrared welding or induction heating a good method of bonding polyethylene (to itself). However, if you need to bond it to a different type of plastic or substrate such as wood, metal, rubber or some kind of composite, it is necessary to look to some other joining method such as industrial adhesive bonding. Polyethylene has a low surface energy so is a fairly non-stick surface. There are several options of surface preparation and industrial adhesive choice that could yield high bond strengths: Corona treatment of surface Plasma treatment of surface Flame treatment Continue reading → Posted in Adhesives on August 27, 2021 by Chemical Concepts. What to Consider When Using an Undermount Sink Adhesive August 16, 2021 There is an influx of products on the market that claim you can hang an undermount sink in seconds without any mechanical anchor. In this post, we hope to provide some “food for thought” and give you some considerations to think about before implementing such a system for your own installations. It sounds great right? Being able to mount a sink in ten seconds without hardware or silicone sealant would be a huge time saver for a lot of fabricators. One of the biggest ways to increase your revenues is to turn around jobs quicker, but to do that successfully you have to make sure your time-saving solutions don’t cut corners.

Structural Adhesives: 3 Benefits Over Traditional Assembly Methods July 6, 2021 Demand for structural adhesives has skyrocketed—even in industries that would have never considered alternative assembly methods in the past. In this post, we discuss the benefits of adhesives and how they are positioned to replace two common assembly methods. Structural adhesives are “load-bearing” adhesives that are used to bond a joint and hold two (or more) substrates together under stress, suitable for a vast majority of composites, thermoplastics, metals, and dissimilar substrates. The results are clean, durable bonds capable of withstanding the harshest climatic conditions with minimal surface preparation. Here are the top three benefits of adhesives. 3 Benefits of Structural Adhesives #1. Light Weighting & Gauge Optimization Continue reading → Posted in Adhesives on July 6, 2021 by Chemical Concepts. How To Install a Removable Panel: 3 Easy Steps May 26, 2021 Fabricators that work with removable panels need an efficient and reliable way to install them. But the processes and hardware you use have a significant impact on the end product. In this post, we break down how to install a removable panel and how to select the right hardware. Removable panels are widely used across a number of industries, including signage, marine, interior design and public transportation. While these industries all have unique application requirements, they have one thing in common. By design, removable panels are going to be attached and reattached dozens or even hundreds of times. So, before you begin the installation, it’s crucial to identify hardware and mounting methods that are strong and durable enough to handle repeated installation.

Choosing a Polyolefin Bonding Adhesive May 20, 2021 Thermoplastic polyolefins like polyethylene and polypropylene, and polyolefin elastomers such as EPDM rubber are notoriously difficult to join. Solvent welding does not produce strong bonds as polyolefins normally have excellent resistance to solvents. Polyolefins have very low surface energies so adhesives do not wet-out the surface well without some form of surface treatment. Surface treatments such as corona, flame, or plasma treating add costs to manufacturing and are often not desired. Cyanoacrylates and acrylics offer the best options. Cyanoacrylate Pretreat the polyolefin with Permabond Polyolefin Primer (POP) and bond with Permabond Cyanoacrylate. This combination will generally create a bond stronger than the polypropylene or polyethylene substrate in shear, however impact strength is limited. POP and cyanoacrylate is a fast, effective solution for many applications. Cyanoacrylate and POP will form bonds with good shear strength and good resistance to non-polar solvents (ex. motor oil, gasoline).

Bonding in Extreme Conditions: How to Select the Right Adhesive for the Job May 3, 2021 Adhesives provide strong, reliable bonds for a variety of applications. But sometimes manufacturing and repair teams have to create bonds in conditions too extreme for standard adhesives. In this post, we break down how extreme conditions impact bonding with structural adhesives. Market Trends for Adhesives & Extreme Conditions There are several industry trends and market conditions that are driving the demand for structural adhesives and products that can perform in what we might call “extreme” environments. Because of these trends, manufacturers and repair technicians regularly encounter conditions that exceed the performance capabilities of standard structural adhesives. Light Weighting Light weighting is a long-term trend where manufacturers replace heavy material with lighter materials, sophisticated designs, hollow-core materials, and composites. New materials, manufacturing techniques, and green initiatives are pushing product fabrication toward thinner, lighter profiles. However, this push for light weighting presents challenges for manufacturers and engineers. In many cases, traditional joining methods like welding, screws, and rivets might not be appropriate or even possible in many situations.

Kenneth Zelle – Our Founder & President Emeritus March 5, 2021 In 1959, in a garage in Northeast Philadelphia, Kenneth & Lois Zelle started what was to become Chemical Concepts Inc. Through hard work and sticking with the basics of taking care of their customers they have cultivated and nurtured the business for 60 years leaving the business to their children and nephews. It is with great sadness that we must announce that Kenneth has passed away quietly in his sleep last night. The family is trying to come to grips with this tragedy and we ask that you keep Ken and our family in your thoughts and prayers. Ken was a veteran of World War Two, serving in the US Army and landing in France on D-Day plus 6 and fighting across Europe until the conclusion of the war in Europe. A member of the greatest generation, he came home to work at various jobs until he decided that his fortunes were to be made working for himself. While Ken did not have a formal engineering degree, he read extensively and studied hard using his acquired knowledge to invent various devices and processes that helped him grow his business from a simple garage to the company we have today. In lieu of flowers, please make a contribution to Fox Chase Cancer Center in Philadelphia. We appreciate your understanding as we mourn the loss of our founder, father, uncle, and leader. -The Chemical Concepts Family Posted in Latest News on March 5, 2021 by Chemical Concepts. ← Older posts Recent Posts How to prepare and bond polyethylene What to Consider When Using an Undermount Sink Adhesive Structural Adhesives: 3 Benefits Over Traditional Assembly Methods How To Install a Removable Panel: 3 Easy Steps Choosing a Polyolefin Bonding Adhesive Categories Adhesives Banshee Blade Bostik Chem-Set CHT Group CounterBalance Countertop Support Brackets Countertops Devcon Dispense Guns Dry-Treat DYKEM Educational Electronics From the Warehouse H2O Glue Hiring Huntsman Information Latest News LORD Corporation Lubricants Lunch and Learns Meet the Team New Products Newborn News Permabond Polytek Potting/Encapsulation Press Release Quantum Silicones SCIGRIP Sign Assembly Sika Silicone Specialinsert Success Stories Techcon Trade Shows Turf-Set Search Sign Up for Our Newsletter: Subscribe ABOUT US Mission Who We Are History Sales Team Careers POLICIES Shipping Returns Terms of Service Privacy Credit SITE RESOURCES Contact Us Blog Literature Learning Center Color Matching Discuss Your Application Site Map Advanced Search Blog © 2021 Chemical Concepts.
