Weathering Resistance
It is the most used engineering plastic in the current market. With its good mechanical properties,
abrasion resistance and self-lubricating function, it is widely used in the mechanical structures
and spare parts. We can also fill the glass fiber and some other fillers to improve its properties,
such as impoving its rigidity, abrasion resistance and impact resistance.
Even if PTFE products have excellent properties, like high/low temperature resistance, chemcial resistance, weathering resistance, dielectric superiority and high lubricity, sometimes we still need to improve its hardness, wear resistance, creep resistance and dimensional stability.
Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.
