An example of a thermoplastic is polypropylene used for butter tubs and plastics used for soft drink bottles, microwaveable containers, and PVC for floor and wall coverings. Traditional TPE types are known as two-phase systems. In some instances, the difference is as high as 10 times the impact. weight. TPE is the generic name used to describe a family of polymeric materials that can be processed as a thermoplastic material, but display a number of characteristics normally associated with traditional thermoset rubb 5. Primary bonds connect molecular chains in thermosetting polymers, which are kept together by strong cross-links. They’re also more expensive than thermoset plastics, on average. Thermosets tend to be strong and stable, as well as highly resistant to chemical reactions. Hexpol on Nov. Thermoplastic composite materials (TPC) have shown excellent properties and features to meet the current and future demands currently fulfilled by TSC structures. The primary challenge in distinguishing an elastomer vs polymer is that elastomers are a subset of polymers. Thermoplastics depend on “addition polymerization process”.
