Websets and Thermoplastics. Before looking onto ther-moplastic elastomeric materials it is necessary to understand the thermosets and thermoplastics first. 1.1. Thermoset Thermoset is a polymer that is cured by heat or chemical reaction and becomes infusible and in-soluble material. Thermoset polymers have a per-manent irreversible polymerization. WebThermosets tend to be more resistant to solvents and corrosive environments than thermoplastics. Thermoplastics and elastomers have been deeply investigated for …

WebThermoplastic Elastomers 139 The transform is more regular and crystallinity can occur, which will prevent elastomeric response. Poly(butadiene) would need to be cross-linked to be a useful elastomer. Polystyrene is a glassy polymer with glass transition temperature =100 °C so it will resist WebThermoplastic elastomers are materials that combine many of the attributes and features of both vulcanized thermoset rubber and thermoplastic materials. Hence, they present an elastomeric behavior while being processed as a thermoplastic polymer. Most thermoplastic elastomers are co-polymers having rigid and flexible moieties in their back …
