A Plastics Primer
Plastics are made up of polymers, long chains of repeated molecule units. The ways in which the chains intertwine determine the plastic’s macroscopic properties. Typically, the polymer chain orientations are random and give the plastic an amorphous structure. Amorphous plastics have good impact strength and toughness. Examples include acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile copolymer (SAN), polyvinyl chloride (PVC), polycarbonate (PC), and polystyrene (PS).
If instead the polymer chains take an orderly, densely packed arrangement, the plastic is said to be crystalline. Crystalline plastics have lower elongation and flexibility than amorphous plastics, but better chemical resistance. Examples of crystalline plastics include acetal, polyamide (PA; nylon), polyethylene (PE), polypropylene (PP), polyester (PET, PBT), and polyphenylene sulfide (PPS).
The characteristics of plastics can be changed by mixing or combining different types of polymers and by adding non-plastic materials. Particulate fillers such as mineral, silica, ceramic, carbon powder/fiber, glass microspheres/fibers and powdered metal are added to increase modulus and electrical conductivity, to improve resistance to heat or ultraviolet light and to reduce cost. Reinforcing glass fibers, carbon, stainless steel or Kevlar can be added to improve mechanical properties.
