Capabilities Process Capabilities Orrex has nine operational lines all located within a 140,000 square foot production and warehouse complex in Odessa, TX. Including: SINGLE LINES (includes lines one, two, four, six, eight, and nine) 44:1L/D, 700 hp, 640 rpm, 92mm W-P twin-screw extruder. Feeds: capable of up to 12 with each controlled by common loss-in-weight or mass flow control system. Feeds include solids from 1 to 4,000 pounds per hour and liquids (initiators, oils, reactants, and stripping agents) from 0.10 gph to 300 gph; feed accuracy to 0.1% of feed rate. Ancillary equipment: One side feeder; two injection ports on all barrels; two independent vacuum systems to 28 in Hg; 8” screen changer; gear pump; pelletizing with Gala underwater, strand or water ring; cooling capacity on contact water to 40F at 3,000 pphr of product @ 400F. Data logging on all control variables. TANDEM LINES (includes lines three-four and five-six) Two independently driven 44:1 L/D, 700 hp, 640 rpm, 92mm W-P twin-screw extruders (see diagram) for a total processing length of 88:1 L/D w/ 1,400 total hp. Feeds: capable of up to 12 with each controlled by common loss-in-weight or mass flow control system. Feeds include solids from 1 to 4,000 pounds per hour of pellets or baled rubber plus liquids (initiators, oils, reactants, and stripping agents) from 0.10 gph to 300 gph; feed accuracy to 0.1% of feed rate. Ancillary equipment: Three side feeders; two injection ports on all barrels; four independent vacuum systems to 28 in Hg; Kreyenborg KSW dual piston screen changer; gear pump; pelletizing with Gala underwater, strand or water ring; cooling capacity on contact water to 40F at 3,000 pphr of product @ 400F. Data logging on all control variables. Line Five-Six also has additional downstream drying and blending capabilities. LAB/PRODUCT DEVELOPMENT LINE (line seven) 50:1 L/D, 50 hp, 580 rpm, 40mm Inconel twin-screw extruder. Feeds: capable of up to 10 total, with each controlled by common loss-in-weight or mass flow control system. Feeds include solids from 1 to 400 pounds per hour and liquids (initiators, oils, reactants) from 0.1 gph to 20 gph; feed accuracy to 0.1% of feed rate. Ancillary equipment: Side feeder; injection ports on all barrels; independent vacuum system to 28 in Hg; 6″ changer; pelletizing with Gala underwater, strand or water ring; cooling capacity on contact water to 40F at 500 pphr of product @ 400F. Line Seven can be operated in reactive extrusion from 25 to 400 pounds per hour. This allows product development and experimentation without high production or feedstock cost. Orrex can pelletize from standard 0.125” to 0.016” diameter / 22 mesh micro-pellets. All vacuum ports on all lines can be located to any position on the reactive stream as required by process design. This is also the case with the side-feeder systems. Orrex operates 24hrs a day, 7 days a week, 365 days a year.

Range of Reactive Agents Currently Employed: Maleic anhydride Organic peroxides Organo silanes Titanates Amines Processing capable from <200 cP to fractional melt; Mooney viscosity from 80 to amorphous <20 Mooney. Laboratory Capabilities FTIR, Nicolet 550 and 560 Mooney viscometer Capillary rheometer MI & MRF Brookfield viscometers Vacuum ovens Color Measurement Furnace for ash determination 1” diameter Killion lab extruder with 6” Killion chilled water cast film tape line with OCS optical gel recording Complete wet chemistry including gel and titration testing Quality and Traceability: Orrex is ISO 9001:2008 registered. All incoming, process and outgoing materials are tracked via bar code scanning and manual input. All materials are recorded to allow 100% traceability of exactly what raw material is used within plus or minus 15 minutes of production. Logistics Capabilities Material Inputs: Rail hopper cars, pellet and powder Rail liquids Hopper truck, pellet and powder Gaylords, supersacks and bags Rail molten polymers Truck molten polymers Drums Material Outputs: Rail hopper cars, pellet Hopper trucks, pellet and powder Gaylords, supersacks and bags Drums Warehouse Storage: 80,000 sf on site Trials and Process Flexibility If equipment is required (testing facilities, non-standard dies, etc.), Orrex can rapidly evaluate necessary capital requirements and return a proposal that will accommodate each party’s abilities and expectations.
