1 Long-term use temperature -80-260℃, has excellent chemical corrosion resistance, corrosion resistance to all chemicals, the lowest friction coefficient in plastic, and good electrical properties, its electrical insulation is not affected by temperature, known as the "king of plastics".

2 Its chemical resistance is similar to poly four vinyl chlorid, better than vinylidene chloride

3 Its creep resistance and compression strength are better than poly four vinyl chlorid, high tensile strength, elongation can reach 100~300%. Good dielectric property, excellent radiation resistance, good flame retardant.

4  Non-toxic: with physiological inertia, can be implanted in the body.
