Glass Fiber Filled PTFE Sheet
Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE. Addition of glass improves compressive properties by as much as 40% and improves wear resistance greatly. These compounds resist acids and oxidation but can be attacked by alkali.
Graphite filled PTFE Sheet
Graphite has good chemical resistance to corrosive environments and exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Commonly blended with carbon and PTFE.
Carbon Filled PTFE Sheet
Carbon has good chemical resistance to corrosive environments. It exhibits good initial wear and rubbing or sliding contact characteristics, both dry and water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.

|
1. Tolerance is according to DIN Length: ﹢0~3 %, width: ﹢0~ 3%. |
|||||||
|
2. it is theoretical value for above spec, with the 1000 x 1000 mm, also we can supply width 100mm ~ 2000mm, Length 1000mm, 1500mm, 2000mm, and more. Thickness 0.1mm ~ 8mm we can Roll. |

|
3. Taking objective as standard, listed data are for reference only. |
|||||||
|
4. The products above have been strictly treated with tempering; the strain value has met the minimum. |
