PTFE Capillary

Polytetrafluoroethylene extrusion tube is made by mixing polytetrafluoroethylene high-pressure dispersing resin with additives into a paste, extruding it from a compact, and then debinding and sintering it. It can be made opaque and semi transparent according to different needs. Due to its advantages of corrosion resistance, aging resistance, non stick, self-lubricating, and good insulation properties, polytetrafluoroethylene can be used for a long time from -180 ℃ to+260 ℃, and is widely used in chemical, mechanical, electronic, pharmaceutical, aviation and other fields.

Shipbuilding
In order to achieve lightweighting of automobiles, effectively reduce costs and fuel consumption rates, major automobile companies generally adopt optimization design methods to design cars, making the materials used for large car coverings thinner and thinner. To solve the problems of insufficient local strength and stiffness caused by this, various reinforcement materials have been developed and widely used in various types of automobiles.
