- Excellent chemical resistance with no aging effects
- Lowest coefficient of friction among solid materials
- Non-stick properties with minimal surface tension
- Physiologically inert and biocompatible
These PTFE components are ideal for corrosion-resistant materials and seals, support sliders, guide rails, electrical insulation parts, and shaft seals across various industrial sectors.
- High lubricity with the lowest friction coefficient among solid materials
- Non-adhesive properties prevent sticking to any surfaces
- Maintains 5% elongation even at extreme low temperatures down to -196°C
- Inert to most chemical solvents, resistant to acids, alkalis, water, and organic solvents
- Exceptional weatherability with the longest aging life among plastics
- Operates effectively at temperatures up to 250°C
For improved wear resistance, increased part stability, enhanced creep strength, and reduced deformation under load, PTFE compounds with 15% or 25% glass fillers are available. These enhanced materials maintain excellent electrical insulation properties while providing superior mechanical performance.
