Engneering Plastics

Engineering plastics are a bunch of plastics that are used most ordinarily in industries because of their enhanced mechanical and thermal properties. They are used mainly in situ of thermoplastic materials instead of thermosetting ones because of the fact that they will be remolded into the specific shape and size whether or not after cooling and settling down. In accordance, to the suitable convention and standards, the definition of engineering plastics (McQuiston, 1980) are: (1) the family of nylon; (2) polycarbonate; (3) polyphenylene oxide; (4) acetal; (5) engineering grade of ABS; (6) polysulphone; and (7) polyphenylene sulphide. Engineering plastics become the fabric of choice for various applications because of their good mechanical, chemical properties, strength, rigidity, self-lubrication, and fire safety. Certain groups of engineering plastics which include polycarbonates and polyamides are useful in industries due to their high resistance to impact and abrasion respectively.
