Acetal, a crystalline thermoplastic polymer with a high melting point, offers many engineering advantages. a high modulus of elasticity coupled with great strength, stiffness and modulus of acetal resin are affected very little by moisture content. and since moisture absorption is relatively low, the dimensional stability of close tolerance fabricated parts is excellent. to a great extent the premium properties of acetal shapes are retained at elevated temperatures. acetal parts can be used for continuous exposure to temperatures up to 185°f, parts are easily fabricated with hand tools as well as by automatic production machines. the excellent combination os properties inherent in acetal makes it ideally suited for mechanical parts and electrical insulators which need exceptional structural strength at above normal temperatures.
