Interstate Plastics

Interstate Plastics is proud to carry Delrin, an industry-trusted name for acetal homopolymer. Delrin is a tough, machinable thermoplastic with a high modulus of elasticity, high strength, good rigidity, dimensional stability, and resistances to moisture, chemicals and solvents. It has desirable toughness properties, performing well at extreme temperatures and under fatigue endurance. A low coefficient of friction (COF) alongside excellent wear properties, especially in wet or moist environments, makes Delrin one of the most widely used engineering thermoplastics on the market today. Low Moisture Absorption Acetal plastics are ideal when working in wet environments as they absorb minimal amounts of moisture and, with a high level of heat resistance, can be heated or cooled without affecting form or dimensionality. Delrin can be used in hot water applications up to 140F without any hydrolysis effect. Unlike other materials that may erode form acidic water, hard water does not harm Delrin.
