Fluoropolymers (PTFE, PVDF, PCTFE, PFA)

PTFE, or Polytetrafluoroethylene, or Teflon is a synthetic fluoropolymer known for its non-stick, lowest-frictional properties. With its superb chemical and dielectric properties, it is widely used in the petrochemical and pharmaceutical industry.

• Non-stick and low Friction
• Temperature range -260°C to +260°C
• High Thermal Stability
• Electrical Insulation
• High Chemical Resistance
• Food safe
• High resistance to UV
• Good electrical properties
• Self-extinguishing

• Low Strength
• Creep under stress
• Difficult to weld and bond
• Cost
• Mechanical properties
• Abrasion resistance, scratched easy.

Pipe linings, oil and gas production, pumps, seals, gaskets, bearings, bridges and much more.

PTFE, reinforced with 25% glass Fibre, offers all the normal properties of PTFE, but with better compressive strength under load, so improving wear properties. Developed mainly for the valve and seal applications.

• Improved Creep Resistance
• Temperature range -200°C to +260°C
• Dimensional Stability
• Electrical Insulation

• Low Coefficient of Friction
• Wear resistance
• Chemical Resistance

• Resistance to alkalis and hydrofluoric acid compared to PTFE
• Friction increase’s
• Surface finish
• Glass-filler is abrasive on machine tools.
• Lower Friction and impact resistance compared to PTFE

Seals, Gaskets, Bearing, Bushes, Insulators, wear pads, slide runners and much more.

PTFE, reinforced with 25% carbon graphite, offers all the normal properties of PTFE, but with improved mechanical, wear and dimensional stability. Used in high performance applications like bearings and seals.
