Blue Glass-filled PTFE
Blue glass-filled PTFE provides enhanced resistance to creep and wear in comparison to virgin PTFE.
Description
Blue glass-filled PTFE sheets, rods and tubes are high-performance engineering plastics that reinforce standard PTFE with 5% to 25% glass fibres. The blue color acts as an indicator for this specific blend. This material has excellent wear resistance, rigidity, and dimensional stability under load.
Other colours, such as red, green, and yellow, are also available.
