PTFE sheets with 15% glass (85% virgin ptfe + 15% glass fibres)

Properties:

Improved compression  and  wear resistance;  excellent chemical stability.  Better thermal conductivity and coefficient of friction when combined with Mos2 or Graphite.

Main applications:

It is the most commonly used filler for dynamic seal applications where both rotating and alternating movements are involved, pneumatic, hydraulic and mechanical parts.

Statement on suitability for contact with foodstuff:

We certify that all our 15% Glass filled molded and extruded semifinished products, made of 15GL, can come in contact with foodstuff, as per the following requirement: USA regulations (FDA, Food and Drug Administration, Department of Health and Human Services; Code of Federal Regulations 21 CFR Ch. 1 § 177.1550 (a) (1) and (b)-Perfluorocarbon Resins.

Overview
 
15% 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. 15% Glass has an exceptional resistance to water. Still giving excellent chemical stability, PTFE +15% 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.
 
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.
