PTFE FILLED DELRIN®
ACETAL HOMOPOLYMER (POM-H) RODS AND PLATES
Low friction and wear applications
PTFE filled Polyoxymethylene Homopolymer (POM-H PTFE) is the semi-crystalline thermoplastic of choice for impact and wear resistance in a wide range of industrial and mechanical applications. POM-H PTFE is easily machined and fabricated, experiencing little dimensional change during machining and use. POM-H PTFE also resists moisture making it an ideal material for use in wet environments. Its exceptional strength, stiffness and dimensional stability bring a high level of durability and resilience to applications in the automotive, electronics and food processing industries.
Key Features
- High tensile strength and tensile modulus
- Low coefficient of friction
- Continuous rigidity and strength at temperatures up to 185° F
- Exceptional resistance to wear, impact and creep in wet and dry environments
- High resistance to hydrocarbons, solvents and neutral chemicals
- Dimensionally stable
- Low moisture absorption
- Easily machined and fabricated
Typical Applications
- Pistons and valves
- Pump components
- Manifolds
- Rollers
- Fittings
- Food product forming dies
- Wear strips
- Timing screws
