Acetal Homopolymer (DelrinÂ®). DelrinÂ® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. DelrinÂ® sheets and rods possess high tensile strength, creep resistance and toughness.It also exhibits low moisture absorption.ecaformâ¢ HPV 13 is a brown homopolymer acetal with an internal PTFE lubricant. Its low coefficient of friction, excellent PV values, toughness, wear resistance, and machinability make it an exceptional material for use in many industrial and military components with moving parts.
