PTFE TUBES

正在加载……

PTFE extruded tubing is manufactured by high pressure PTFE dispense resin mixed with additive, it is extruded and sintered. According to different demands, the tubing could be opaque or translucent.

KEY PROPERTIES

High and Low Temperature Resistance, continuous operating temperature 70℃~+260℃

Corrosion Resistance, chemically stable except fluorine gas, alkali metals dissolved

Weatherability, the best anti-aging plastic; Outdoor long-term use will not degrade

High Lubrication, the lowest coefficient of friction of any polymer

Non-adhesive,  prevent the adhesion of almost all pollutants, water contact angle            θ =110 º

Non-toxic, doesn’t cause allergic reactions, compatible with human tissue and body fluids

Flame resistance, non-combustible in air (oxygen index> 95%)

Electrical properties,  Excellent electrical insulation, broadband dielectric constant and loss factor minimum

APPLICATION

Mechanical Equipment, Aviation, Auto Parts, Chemical Tubes, Electronics, Cables, Medical Equipment etc.
