Some thermoplastics withstand extremely high temperatures while others can withstand only low temperatures. The properties of these coatings depend on the basic properties of the resin. Upon heating, thermoplastics become soft and malleable, especially in the vicinity of their particular glass transition temperature. Thermoplastic Elastomers. Thermoset composites (i.e. Some of the most important thermoplastics are polyethylene [low density polyethylene (LDPE) and high density polyethylene (HDPE)], polypropylene (PP), poly(vinyl chloride) (PVC) and polystyrene [44]. However, thermoplastic elastomers (TPEs or thermoplastic rubbers) make it possible for thermoset materials to behave similar to thermoplastics. In the past, all rubber materials were thermoset, meaning they could no longer be changed once the injection molding process was complete. These characteristics, which lend the material its name, are reversible, so the material can be reheated, reshaped, and frozen repeatedly. There are many benefits associated with thermoplastic silicones, but very few examples exist: silicone resins or rubbers are normally thermosets. Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. They are generally used for lightweight structures, storage tanks, door and window frames and panels. Depending on the resin, thermoplastics can serve low-stress applications such as plastic bags or high-stress mechanical parts. Thermoplastic elastomers with unusual structures and properties include star block copolymers, thermoplastic interpenetrating networks (IPNs) and polyacrylates.
