Polyurethane versus Plastic

The plastics family generally include materials with a wide range of chemical compositions, including variations of carbon and hydrogen molecules. Examples of plastics consists of polyethylene, PVC, nylon and ABS. Strictly speaking, thermoset polyurethanes are NOT considered a "plastic". Instead, the long flexible polymer molecules that comprise thermoset polyurethanes make this material a true elastomer. Typically, thermoset polyurethanes are either cast molded or Reaction Injection Molded (RIM), while plastics are often injection molded. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. 

Thermoset Polyurethane VS Plastic 

Thermoset polyurethanes have many advantages over plastics for a variety of applications, including: 

  • Elastomeric memory allows polyurethane to return to its original shape when stretched, bent or deformed
  • Superior durability and resiliency at harder durometers
  • Outstanding impact and abrasion resistance
  • Physical properties can be engineered to meet demanding specifications
