Product Description

Product Description

PTFE material resists attack by heat and virtually all chemicals. It is insoluble in all organics with the exception of a few exotic strong base chemicals. Its electrical properties are excellent. Although it has high impact strength, its resistance to wear, tensile strength and creep resistance are low in comparison to other engineering type thermoplastics. Mechanical properties can be improved by adding fillers such as glass fibers, bronze, Delrin, carbon, and graphite.

Main Properties & Application

• Excellent corrosion resistance
• Good electrical insulation performance
• High temperature resistance
• Low coefficient of friction
• Good non-sticky properties

PTFE semi-finished rod,tube(bushing) and sheet is widely used in chemical anti-corrosion,mechanical seal,engineering piping,electrical insulation,pump&valve fluid,aviation,textile,ceramic and other industries.
