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).
