Thermosoftening structure
WebbHere are some examples of thermosetting plastics. 1. Vulcanized Rubber. Vulcanized rubber is a type of thermoset plastic as once it is molded, it retains its shape and can’t be recycled again. The untreated rubber is converted into the vulcanized rubber through a process called vulcanization. WebbThermosets are a class of important polymers having three-dimensional cross-linked network structures. Typical thermosets such as epoxy resin, phenolic resin, and unsaturated polyester resin have been widely used as electronic encapsulating materials, coatings, adhesives, and matrix of composites [1–5].

WebbThermoset polymer matrix polyimides exhibit very low creep and high tensile strength. These properties are maintained during continuous use to temperatures of up to 232 °C (450 °F) and for short excursions, as high as 704 °C (1,299 °F). [14] Molded polyimide parts and laminates have very good heat resistance.
