PTFE TW (Polytetrafluoroethylene) is a non-flammable, thin-wall sleeving with an exceptionally high operating temperature of -70°C-+260°C. It has a very low coefficient of friction, high dielectric strength and is virtually inert to all chemicals. It is available in many colours and AWG, metric and imperial sizes as standard. Bespoke sizes, wall thicknesses and colours are also available.

PTFE hose and convoluted tubing is ideal for enhanced protection of wire, cable, electrical and electronic components for commercial and high performance military and aerospace systems. It is extremely stable at very high temperatures and retains a measure of toughness and strength even at cryogenic temperatures. It is virtually inert to all chemicals resisting most acids. Alkalis and petroleum products. It is virtually unaffected by oxygen, ozone and UV light. It is extremely hydrophobic and has a UL 94 rating of V-O. It also has a very low co-efficient of friction and high dielectric strength and excellent mechanical properties.
