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).
