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

Performance
| Glass Fiber | Increase compressive strength, rigidity and wear. Reduces creep and cold flow Minimal effect on chemical and electrical properties |
| Carbon | Increases compressive strength, hardness, wear, and load properties. Good chemical resistance Various types and amounts of carbon can be added to alter conductivity |
| Graphite | Reduces coefficient of friction Reduces initial wear Increases strength |
Molybdenum Disulfide | Increases hardness, stiffness, and wear Minimal effect on chemical and electrical properties |
Bronze | Increases hardness and wear resistance Increases dimensional stability and compressive strength Not suitable for corrosive or electrical applications |
MAIN PROPERISE:
1. Apparent density: 2.10~2.30g/cm3;
