100% Virgin Thickness 0.5~60mm Skived PTFE Sheets
Features of PTFE :
1. Superior endurance in corrosion
2. Non-flammable, limited oxygen index is under 90
3. Low friction coefficient
4.Non-viscous, Self-lubricating
5. Superior endurance in high & low temperature, can be used at -1800~260°C
6.High electricity insulation
7.Atmospheric aging resistance, Good gas barrier property
8.Low permeability , Good gas barrier property
9.Good physiological compatibility and anti-thrombotic
1)PTFE Molded sheet: Using molding method to produce this kind of sheet. In big blocks, normally Lenght and Width has standard size, max size is 1000*2000mm.

2)PTFE Skived sheet:Or we can call it film as well, thin thickness, width from 10~1200mm, packed in roll, continue lenght around 30-50M or more, detail lenght depends on the thickness.
Specifications:
Iterms | Thickness | thickness devation | width |
direct film | 0.03-0.10 | ±0.02mm | 10-20 |
skived film | 0.10-0.49 | ±0.03mm | 10-300 |
skived film | 0.50-1.0 | ±0.05mm | 10-1000 |
skived tape | 1.10-5.0 | ±0.1mm | 10-1200 |
Filled material:
Filled PTFE ring has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.
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 |
