There are three types of PTFE pipes: For a pipe with outside diameter 1~25mm and thickness of wall 0.1~2.5mm, we choose 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 choose suspended PTFE resin and process it by extruding; For a pipe with outside diameter 25~120mm and thickness of wall 5~500 mm, we process it by die pressing.

Features
Strength (high strength-to-weight ratio)
Chemical inertness of this PTFE teflon oil seal is good
Biocompatibility
High thermal resistance
High chemical resistance in harsh environments
Low flammability
Low coefficient of friction
This PTFE teflon oil seal has low dielectric constant
Low water adsorption
Good weathering properties
PTFE resin,filled with some filling stuff,can prolong the life of products and strengthen the performance,eg:Graphite,Carbon ,Glass fiber ,bronze
Glass Fiber: |
Increases compressive strength, rigidity and wear. |
Carbon: |
Increases compressive strength, hardness, wear, and load properties. |
Graphite: |
Reduces coefficient of friction |
Molybdenum Disulfide: |
Increases hardness, stiffness, and wear |
Bronze: |
Increases hardness and wear resistance |
