POLYOXYMETHYLENE (POM) / POLYACETAL SHEETS AND RODS
Product Description
Polyacetal (POM) sheets and rods are among the strongest and stiffest of all thermoplastics. 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.
Features
- • High mechanical strength
