15% Polyimide-Filled PTFE
10% polyimide-filled PTFE material comes in tube, sheet, and rod shapes. The polyimide filler in PTFE can be 10%, 15%, or 20%.
Welcome to Learning About 15% Polyimide-Filled PTFE
Compared to virgin PTFE, 15% polyimide-filled PTFE material is more durable and has a longer service life. It works especially well in dynamic systems where continuous friction and mechanical stress expose components.
15% polyimide-filled PTFE material is a novel family of materials that combines the unique qualities of PTFE with the superior thermal and mechanical capabilities of polyimide. This results in a composite material that is stronger, more durable, and versatile in various industries and applications.
Advantages
15% polyimide-filled PTFE offers several benefits, including:
- Superior high-temperature resistance.
- Excellent sliding and wear qualities.
- Excellent high pressure resistance.
- Improved mechanical strength.
- Very low friction coefficient.
- Increased toughness
Application
The 15% polyimide-filled PTFE is commonly used in piston rings, rubber cups for oil-free pumps, bushings, gaskets, and other components.
