#7 plastic includes all other types of plastic not included in the first six recycling codes. Two common "other" plastics are polycarbonates and ABS plastic. Polycarbonates are condensation polymers. One common polycarbonate is made from bisphenol A and phosgene. This plastic is found in eyeglass lenses. ABS plastic is an addition polymer and formed from three different monomers - acrylonitrile, butadiene, and styrene. ABS is normally used for high-impact protection, such as in football helmets and some car body parts.
