40% Bronze Filled Tube


40% bronze filled PTFE tube


CNC bronze filled tube

Product Description

40% Bronze Brown Color Filled PTFE Tube / Pipe / Tubing With Different Sizes 200-300 Mm For CNC Seals Machine





There are three types of PTFE pipes: For a pipe with outside diameter 1-25mm and thickness of wall 0.1-2.5mm, we use imported polymerized PTFE resin and process it by pressing; For a pipe with outside diameter 25-200mm and thickness of wall 1.5-8mm, we apply suspended PTFE resin and process it by extruding; For a pipe with outside diameter 25-120mm and thickness of wall 5-500mm, we process it by die pressing.




Strength(high strength to weight ratio)

Glass Fiber

Increase compressive strength, rigidity and wear.

Reduces creep and cold flow

Minimal effect on chemical and electrical properties


Increases compressive strength, hardness, wear, and load properties.

Good chemical resistance

Various types and amounts of carbon can be added to alter conductivity


Reduces coefficient of friction

Reduces initial wear

Increases strength


Molybdenum Disulfide

Increases hardness, stiffness, and wear

Minimal effect on chemical and electrical properties



Increases hardness and wear resistance

Increases dimensional stability and compressive strength

Not suitable for corrosive or electrical applications
