Properties of thermosetting plastic
WebApr 6, 2024 · Thermoplastic is a plastic that has a strong force of attraction. These types of plastic become soft on heating and become hard on cooling. These types of plastic can be reshaped and remelted into a variety of shapes. Common examples of thermoplastic are polyester, Teflon, polystyrene, and polypropylene. Types of Thermoplastics WebSep 29, 2024 · The applied heat (or chemical catalyst) causes the polymer chains in a thermoset plastic to cross-link with each other, holding the molecules more firmly in position. Crosslinking changes the properties of the material, making it impermeable and rigid. Once the crosslinking chemical changes take place, thermosetting polymers cannot …
