PTFE Tube is made from PTFE suspension resin or PTFE dispersion resin and prepared by paste&ram extrusion and compression molding.It is divided three types of Push Tube,Extruded Tube,Moulded Tube. The white color and luster is even,there are no crackle and bubble,excellent properties of enduring chemeistry&corrosiveness,dielectric,non-ageing,airtightness,hight lubricity and non-stick.It has a wide range of practicable temperature from -180℃～+250℃ and a wax-like surface where anything hardly sticks on and the lowest coefficient of friction of all known solid materials.It conforms to the professional standard QB/T 3624-99.
