• The ABCs of ABS
  ground-effects package consisting of a front cap assembly that covers the well for holding LP bottles, wheel-well skirting, and the rear bumper. The parts are coextruded sheets of Lustran ABS resin capped with Centrex 825 weatherable polymer. The front panels and sinks for the QPA-160 and QPA-310 ice dispensers...
• ABS/SAN
  applications, ABS resins can be coextruded with a compatible weather-resistant polymer on the outside surface. ABS resins are stable in warm environments and can be decorated with durable coatings that require baking at temperatures to 160°F for 30 to 60 min. Heat-resistant grades can be used for short...
• Weathering of Plastics (.pdf)
  or discolors in service. ABS may be more than adequate mechanically for many outdoor applications but the weathering response of ABS means that it is rarely selected for such applications. Asking and adequately answering the question 'How long will it last in service?' must be a key factor...

The optical behavior of crystalline plastics is more complex because of the presence of the. crystallites and their effect on the light. · Crystal density...
• Types of Plastics
  temperatures. Examples of amorphous thermoplastics are ABS, polystyrene, polycarbonate, polysulfone, and polyetherimide. Crystalline plastics include polyethylene, polypropylene, nylon, acetal, polyethersulfone, and polyetheretherketone. Copolymer structures. Another method for altering molecular...
• Bonds that take a beating
  flowability, sag resistance, and thermoplastic-bondability. The polyurethane resists run-out as panels are inverted and joined during assembly. The adhesive also effectively joins ABS to a more flexible panel made from Telene RIM polymer from Cymatech LLC, Calvert City, Ky., without read-through on cover...
• Gas-Assist Molding: Not just for hollow parts
  front enclosure was molded using gasassist on a 1,000-ton press rather than the 2,000-ton press necessary for straight injection. This let Home Decorator Inc., Raleigh, N.C., meet cost and time-to-market targets. Also important was a cosmetic appearance on the PC/ABS part straight from the mold...
• UV Properties of Plastics: Transmission and Resistance (.pdf)
  . All types of UV can cause a photochemical effect within the polymer structure, which can be. either a benefit or lead to degradation of some sort to the material. Note that compared to our. skin, the higher energy UVC is more likely to affect plastics. Degradation. The main visible effects...
• Synthetic lubricants for the long haul
  polymer chains which make them flexible molecules able to remain fluid at lower temperatures than pendents. Pendent molecules have side chains, sometimes called branches, which make them more rigid. While these branches decrease the molecule's flexibility, they form a series of lattices that help...
• Plastics Consultancy Network - Recycling
  be produced.. ABS is widely used in the automotive and electrical industries for switch housings etc. The mechanical properties of recycled ABS contaminated with ink and other polymers added at various levels to virgin polymer have been studied.[10,11]. Nylon 6,6 (PA6,6) from automotive radiator end...
