Polypropylene: PP Polystyrene: PS Low-density polyethylene: LDPE Properties of Plastics The properties of plastics depend on the chemical composition of the subunits, the arrangement of these subunits, and the processing method. All plastics are polymers but not all polymers are plastic. Plastic polym...
Thermoplastic polymersor thermosoftening plastics are the other type of synthetic polymers. While thermoset plastics are rigid, thermoplastic polymers are solid when cool, but are pliable and can be molded above a certain temperature. While thermoset plastics form irreversible chemical bonds when cured, ...
while fibres are obtained from artificial or man-made sources. They consist of a small unit or a polymer which is made from many repeating units known as monomers. They include nylon, acrylics, polyurethane, and polypropylene. Millions of tons of these fibres are produced all over the world ...
