a linear polymer consisting of unbranched polyoxymethylene chains
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.
