Glass/PTFE fabrics and rolls

Fabrics and Rolls in Glass-TEFLON®

Many industrial applications require materials with specific characteristics:

  • High temperature resistance
  • Anti-adhesive properties
  • Chemical substance resistance

These conditions require the use of various products composed of glass-PTFE fabric, which is generally referred to as glass-TEFLON®; these products are composed of a glass fibre fabric coated with various PTFE (TEFLON®) solutions.

These fabrics can be joined with various junction solutions in order to form conveyor belts, or can be supplied directly as open ended belts with either thermoplastic or metallic junctions on both ends in order to be then joined once they’ve been fitted on the machine.

Glass-PTFE fabrics can either be supplied cut to shape or as entire rolls, they are also available with one adhesive side so that it can be fixed directly on metal surfaces of machinery or on the moulds used.

Thanks to its partnership with various photovoltaic machinery constructors, Novitec, has developed various products for this specific sector.

Glass-PTFE fabrics, rolls and conveyors

Novitec develops both glass fibre and aramid fibre (KEVLAR®) fabrics with various grammages coated with either PTF (Teflon®) or silicone.

Thicknesses between 0,120 mm and 0,675 mm are available, and can be supplied with various mechanical resistances; an antistatic version is also available.

Main characteristics of these products:

  • Non-stick surface
  • Dimensional stability within the – 65°C and the + 280°C range
  • Possibility to have them food grade certified
  • Excellent resistance to both chemicals and wear
