Customized size F4 bushing teflon flange

Product Description ●PTFE Gaskets (Virgin Teflon Gaskets) Virgin PTFE (Teflon) gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets. It possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load.  ●Filler PTFE Gaskets Filled PTFE (Teflon) gaskets are made from PTFE which integrates additives and fillers in order to improve the performance of the gasket. This improves the gaskets ability to wear and enhances its unique combination of chemical, physical and electrical properties. Filled Teflon is the most common type of PTFE gasket for industrial use as it exhibits improved mechanical strength compared to Virgin PTFE. Glass, carbon and fiber particles are typical fillers that are used to enhance the mechanical strength of the gasket depending on the application. Our most common PTFE filled grades include:

▶PTFE, Glass Filled Gaskets The percentage varying between 5 and 40%.
1, Increases compressive strength.
2, Rigidity and wear.
3, Reduces creep and cold flow.
4, Minimal effect on chemical and electrical properties.
▶PTFE, Carbon Filled Gaskets Carbon is filled to the PTFE in a percentage by weight between 10 and 35%.
1, Increases compressive strength.
2, Hardness, wear and load properties.
3, Good chemical resistance.
▶PTFE, Graphite Filled Gaskets The percentages used vary between 5 and 15%. 
1, Reduces coefficient of friction
2, Reduces initial wear
3, Increases strength
4, Compatible with most hydraulic fluids
5, Improve the temperature resistance
PTFE (Polytetrafluoroethylene) Known as the gold standard, PTFE material is often the first choice for many advanced applications such as aerospace, electronic, medical, chemical industry due to its superior lubricity, temperature and chemical resistance, biocompatibility and lowest coefficient of friction. Properties：
1, Low coefficient of friction;
2, Flexibility at low temperatures and thermal stability at high temperatures，Broad working temperature range (500°F/260°C – -292°F/-180°C);
3, Chemically resistant – all normal solvents, acids, and bases;
4, Low dielectric constant and low dissipation factor;
5, Non-flammability;
6, Non-stick, Easy to clean;
7, Long-term weathering;
8, High arc resistance, surface and volume resistivities. Packing & Delivery Packing Details  : Inner plastic bags, packed in carton box. Delivery Details : 7-15 days for normal order. Carton Package for courier: DHL/ FEDEX/ TNT/ UPS Wooden Package for heavy goods, normally ship by sea or air cargo.
