Highly crystalline (as high as 97%) thermoplastic made from linear polyoxymethylene. Excellent creep resistance and fatigue endurance. Two main classes: homopolymer and copolymer. May need to be dried for processing. Semicrystalline material.
Acetal resins based on formaldehyde are high performance engineering plastics with superior abrasion resistance and toughness; may require pretreatments to enhance adhesion properties.
A rigid thermoplastic with properties similar to zinc, aluminum, and other metals. The molecular structure of the polymer is of a linear acetal consisting of unbranched polyoxymethylene chains.
A plastic tough, stable engineering thermoplastic with a high modulus of elasticity, high strength, good rigidity, dimensional stability, resistance to moisture, solvents, and other chemicals.
A crystalline thermoplastic with a high mechanical strength and excellent wear properties with a very low moisture absorption rate resulting in excellent dimensional stability. Commonly used to support frames and handles in the luggage industry.
