Plastim PTFE +25% Glass Filled

PTFE +25% GF

Overview

25% Glass filled PTFE is used to improve the creep resistance of PTFE over all temperature ranges, while still allowing some compression required for sealing in both gaskets and valves. Improved wear behaviour is exhibited, while there is little effect on the electrical properties, as glass fibre is an insulator. 25% Glass has an exceptional resistance to water. Still giving excellent chemical stability, PTFE +25% GF has better thermal conductivity and coefficient of friction when combined with MoS2 or graphite.

Benefits:

High chemical resistance.
Resistance to both low and high temperatures.
Low flammability.
Low friction coefficient.
High resistance to UV.
FDA Approved.
Good electrical properties.

Weaknesses:

Compared to high-performance plastics, this product still has poor mechanical properties, despite being better than virgin PTFE.

Applications:

Pump housings, valve seats, gaskets, roller coverings, shaft bearings, filter housings, etching plates, shaft seals, slide runners, chemical engineering, machine parts, transport and conveyor technology, pump and instrument construction, electrical industry, electronics, laser technology, fume purification, pure water production, cryogenics, filter technology, food and medical technology.

Virgin, glass-filled and carbon-filled PTFE are FDA (USA) approved for use in contact with food, potable water and pharmaceutical products.

High chemical resistance to alkali and acids is the main feature of the fluoropolymers. PTFE is used for parts in the petrochemical and chemical industries.
