PTFE 

Officially in the record books as having the lowest co-efficient of friction of any solid material and is extremely effective operating at extremely high and low temperatures. PTFE has fantastic chemical resistance and superb electrical insulation properties. PTFE can be tricky to bond, but it is none melting and is self extinguishing. Our virgin grade PTFE is available in white only. PTFE is an extremely versatile engineering plastic that has many important performance advantages over other materials and has helped PTFE become one of the most important engineering materials available at the moment.

 Characteristics of PTFE

One key important advantage of PTFE is its operating temperature range, it can easily out perform other engineering plastics by being able to perform continuously at -250°C, right up to an amazing 250°C. Another important advantage of PTFE is its outstanding co-efficient of friction, PTFE is in the record books as having one of the lowest friction values known to man. PTFE also has excellent acid and chemical resistance. Another feature of PTFE is its ability to set by or due to compression. PTFE has excellent electrical resistance. PTFE is also water repellent and is often used in the manufacture of modern high performing, water repellent and breathable clothing. 

Applications for PTFE

PTFE is excellent for low friction bearings, bushes, rollers and pulleys. PTFE is also almost exclusively used in cryogenic components due to its ultra low operating temperatures. PTFE Rod is regularly used for seals. PTFE Rod has become a very important engineering plastic used within the aerospace industry and aeronautics. PTFE is often used within the food industry companies. Another useful application over the years has been in the use of product or component handles due to its resistance to heat and heat transfer. When an application for electrical resistance becomes too high for other materials, PTFE Rod can fill a very important gap.

Advantages of PTFE

Because PTFE has such a low co-efficient of friction it offers a material that when used will reduce load and drag in bearings to improve efficiency and reduce frictional losses and PTFE will outlast other materials. Because PTFE will set due to compression, PTFE will conform to mating components resulting in excellent sealing capacity. PTFE is reasonably easy to machine which helps with reduced machining costs and increased capacity and efficiency. PTFE is resistant to most acids allowing this material to be used in aggressive environments to where such materials as Polypropylene are unsatisfactory. .

Features of PTFE

1. Usage temperature range is very broad (Celsius from - 200 degrees to +260 degrees).

2. Anti-majority chemical substance's corrosiveness, except some fluorides and alkalinity molten metal.

3. Excellent mechanical properties, aging resistance.

4. Excellent flame resistance(Conforms to ASTM-D635 and D470 test step),in the air to be regulated as a flame retardant material.

5. Very low water absorption.

6. Has the self lubrication and not the coherency.

7. Excellent insulation characteristic (Regardless of its frequency and temperature how)
