Virgin PTFE / Pure PTFE
Offers outstanding chemical resistance, extremely low friction, and high flexibility. Ideal for seals, gaskets, insulating components, valve parts, and chemical-resistant applications where dimensional stability and smooth sliding surfaces are critical.
Glass-filled PTFE
Enhanced mechanical strength, wear resistance, and dimensional stability due to glass fiber reinforcement. Commonly used for industrial bushings, structural components, guide rails, and precision mechanical parts that require higher load-bearing capacity.
Carbon-filled PTFE
Provides improved wear resistance, reduced deformation, and better thermal conductivity. Suitable for bearings, piston rings, sliding components, valves, and other parts exposed to repeated friction or moderate mechanical stress.
Bronze-filled PTFE
High hardness, excellent wear resistance, and increased load capacity. Perfect for heavy-duty bushings, bearings, sliding plates, hydraulic components, and machinery parts that require both strength and chemical resistance.
Graphite-filled PTFE
Self-lubricating, heat-resistant, and dimensionally stable. Used for high-temperature seals, valve seats, sliding parts, gaskets, and industrial components requiring low friction and long-term wear performance.
Stainless steel-filled PTFE
Offers superior load-bearing capacity, improved wear resistance, and high structural strength. Ideal for high-load mechanical parts, industrial machinery components, heavy-duty bushings, and parts operating under extreme conditions or repeated stress.

The manufacturer is strongly recommended. In the past few years of cooperation we have ordered several machined products from aluminum and stainless steel. These products are manufactured in compliance with tolerance requirements and require product finish. Now I have ordered another one. The service is excellent and any questions can be answered and resolved in time.
2021-05-13
The dimensions are all customized according to my drawings no tolerance issues and the parts are delivered on time. I am very satisfied with it.
