(Acetal Homopolymer). DELRIN® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. Acetal Homopolymer (Delrin®). Delrin® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. Delrin® sheets and rods possess high tensile strength, creep resistance and toughness.It also exhibits low moisture absorption.
DELRIN ® DELRIN ® (Acetal Homopolymer) DELRIN ® is a crys-talline plastic whichoffers an excellent balance of propertiesthat bridge the gapbetween metals andplastics. DELRIN ® possesses high tensilestrength, creep resist-ance and toughness.It also exhibits lowmoisture absorption.  Keck Clips made of polyoxymethylene. Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability.  Click to enlarge. Delrin® is an acetal homopolymer with an excellent balance of properties that bridges the gap between metal and plastic. Delrin Sheet is known for low moisture absorption, high tensile strength, creep resistance, and durability.  Delrin® is a homo-polymer Acetal produced by Dupont. The generic Acetal covers both the homo-polymer Delrin® and the co-polymer grades of resin. Both materials meet the ASTM-D-4181, ASTM-D-6100 or ASTM-D-6778 specification (an old call out is L-P-392). Homo-polymer is POM111, and Co-polymer is POM211. ACETAL Acetal is the common name for a family of thermoplastics with the chemical name PolyOxy-Methylene. Acetal is available in a general purpose copolymer grade, a homopolymer version (Delrin ®), and several filled grades. Acetal provides high strength and stiffness, enhanced dimensional stability, and is easy to machine. An acetal is a functional group with the following connectivity R 2 C(OR') 2, where both R' groups are organic fragments. The central carbon atom has four bonds to it, and is therefore saturated and has tetrahedral geometry. The two R'O groups may be equivalent to each other or not. The plastic known as acetal is a polyacetal of formaldehyde. Acetals are used as protecting groups for carbonyl groups in organic synthesis as they are stable with respect to hydrolysis by bases and with respect to many oxidizing and reducing agents. Acetal Homopolymer (Delrin®). Delrin® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. Delrin® sheets and rods possess high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption. Differences Between Acetal Products. There are two general types of acetal resins available: Acetal homopolymer and acetal copolymers. Each type of acetal has its own set of advantages and disadvantages. Acetal (polyoxymethylene, POM) is a thermoplastic polymer commercialized in the early 1960's. DELRIN (Acetal Homopolymer). DELRIN® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. DELRIN® possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption. It is chemically resistant to hydrocarbons, solvents and neutral chemicals GENERAL PROPERTIES Acetal is the common name for a family of thermoplastics with the chemical name PolyOxy-Methylene. Acetal is available in a general purpose copolymer grade, a homopolymer version (Delrin ®), and several filled Delrin ® grades.
