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 and nylon. Strictly speaking, cast thermoset polyurethanes are NOT considered a "plastic". The long flexible polymer molecules that comprise thermoset polyurethanes make this material a true elastomer. Unlike polyurethane, plastics will tend to remain permanently deformed or even break when applied with stretching, abrasion or impact forces.

Thermoset polyurethane versus plastic: 

In conclusion, cast thermoset polyurethanes has many advantages over plastics for many 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 abrasion and impact resistance, resulting in longer life
  • Polyurethane’s physical properties can be engineered to meet demanding specifications
