C9021TF POM PTFE Oil Resistant PTFE Raw Material Home Appliance Components

1. Comparison of basic characteristics
Characteristics POM (polyformaldehyde) PTFE (polytetrafluoroethylene)
Chemical structure Linear crystalline polymer, containing repeated formaldehyde units perfluorocarbon chain structure, carbon-fluorine bond is highly stable
Density 1.41-1.42 g/cm³ 2.14-2.20 g/cm³
Operating temperature -40℃ to 100℃ (short-term 120℃) -200℃ to 260℃ (short-term 316℃)
Color Milky white translucent pure white opaque
Second, core performance advantages
Three features of POM
High rigidity and low deformation: elastic modulus 2800-3500 MPa, suitable for precision gears, bearings (2025 AI robot joint parts mainstream material).
Wear-resistant self-lubrication: friction coefficient 0.1-0.3, still maintain stable operation in oil-free environment (example: new energy vehicle charging gun locking mechanism).
Fatigue resistance: Excellent fracture resistance under cyclic load, dynamic component life of more than 100,000 times (2025 drone propeller connector standard).
Four advantages of PTFE
Ultra-low coefficient of friction (0.04-0.1) : lowest for all solid materials (applied to the 2025 Mars rover sliding seal ring).
Extreme corrosion resistance: strong acid, strong alkali, organic solvent (example: nuclear power plant reactor gasket upgrade material).
Wide temperature range stability: -200℃ still maintains toughness, 260℃ no decomposition (2025 superconducting cable insulation layer preferred).
Dielectric properties: dielectric constant 2.1, zero loss of high frequency signal (6G communication base station radome core material).
