POM-POLYACETAL ROUND RODS
Polyacetal sheets, plates and rods are among the strongest and stiffest of all thermoplastics. Polyacetal and Delrin plastic materials are characterized by good fatigue life, low moisture sensitivity, and high resistance to solvents and chemicals. Polyacetal products also contain good electrical properties. Homo-polymer and Copolymer grade of Polyacetal are available including an enhanced bearing grade material.

Polyacetal -POM is a semi crystalline engineering plastic that is beneficial to engineering applications, and is suited to CNC machining

Polyacetal - POM Sheet & Delrin Rods Characteristics:
  • High mechanical strength
  • Excellent resilience
  • Good creep resilience
  • High impact strength, even at low temperatures
  • Very good dimensional stability
  • Good sliding properties and wear resistance
  • Excellent machinability
  • Physiologically inert (most grades are suitable for food contact
Polyacetal -POM Sheet & Rod Applications
Gear wheels with small modulus, cams, heavily loaded bearings and rollers, bearing and gears with small clearances, valve seats, snap fit assemblies, dimensionally stable precision parts, and electrically insulating components.

Polyacetal -POM Products

Polyacetal (POM-C) Color: Natural (white) / black

Polyacetal Co-polymer, (POM-C) is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation than the polyacetal homo-polymer (POM-H).

Polyacetal (POM-H) Color: Natural (white) / black

Polyacetal Homo-polymer (POM-H) has higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate when compared to polyacetal (POM-C) and often it also presents a better wear resistance.
