Thermoplastic Rubber - TPR |
|
Processed like a Thermoplastic but behaves like an Elastomer. They are made by copolymerizing two or more monomers, using either block or graft polymerization techniques. One of the monomers develops the hard, or crystalline, segment that functions as a thermally stable component (which softens and flows under shear, as opposed to the chemical crosslinks between polymeric chains in a conventional, thermosetting rubber); the other monomer develops the soft, or amorphous segment, which contributes the rubbery characteristic. These materials can be processed in Plastic tooling, and the scrap can be recycled and reused. Can be used for flexibility, non-abrasive /non-marking, or skid resistance. |
