Description

TETRON HG is the trade name for high percentage glass-filled polytetrafluoroethylene (PTFE). Glass fibre is the most commonly used filler, resulting in a lowered deformation under load at both high and low temperatures. Wear behaviour is also improved.

  • Avoid use with Hydrofluoric Acid (HF) and strong alkalis.
  • The glass fibre used is E-glass milled fibre, nominal diameter 13 microns to ensure even dispersion and optimum properties.
  • TETRON HG mouldings have a homogeneous and dense structure. The surface is smooth with a white to light grey appearance.

Tetron HG Applications:

  • Piston rings
  • Valve seats
  • Shaft seals
  • Electrical insulators
  • Bearing pads
