KEYLON® PTFE is a unique thermoplastic and is resistant to almost all corrosive chemicals, except for alkali metals.

Some of its main characteristics are:

• Chemically inert to all known industrial chemicals;
• Low co-efficient of friction, non-stick & non-toxic;
• Wide temperature range (-260°C to +260 °C);
• Exhibits excellent permeation resistance;
• Excellent dielectric properties;
• Adding fillers to KEYLON® PTFE increases wear-life and hardness.

KEYLON® PTFE stock shapes (tubes, rods & sheet) are available in the following grades:

• Virgin Grade (no fillers added)
• Glass Filled
• Bronze Filled
• Carbon Filled
• Graphite Filled
• Various other fillers available on request.

1.PTFE Virgin Grade has the lowest coefficient of all materials and is ideal in applications where lubricants are not desirable as KEYLON® PTFE functions without any lubricants. PTFE has the widest working temperature range of all plastics, from -260°C to 260°C. PTFE is excellent for use in cryogenic applications as shows no embrittlement. KEYLON® PTFE has very good sealing properties. PTFE is not flammable unless in 94% oxygen environment. KEYLON® PTFE is an excellent insulating material. KEYLON® PTFE is not ideal in high wear abrasive applications or in high loading applications. Here filled PTFE is used to improve resistance to load and wear.

APPLICATIONS:

Chemical applications, sealing applications, insulating materials in demanding electrical applications, and low friction applications. Gaskets, bearing pads, chemical equipment, valve seats, valves in gas cylinders, bellows etc.

2.Bronze filled KEYLON® PTFE contains a copper/tin alloy providing a better creep resistance than most of the PTFE alloys. It exhibits improved thermal conductivity, with high load bearing capacity and hence is most often used in hydraulic systems. Bronze filled KEYLON® PTFE is both thermally and electrically conductive. The bronze enhances dimensional stability due to improved hardness, compressive strength and resistance to creep. Bronze filled KEYLON® PTFE is not to be used in contact with oxidizing agents.
