Ptfe what is it used for

Polytetrafluoroethylene, or PTFE, is a versatile polymer that has been in use since There are many uses of PTFE in industrial and consumer applications. The two main components of PTFE are carbon and fluorine. This combination gives PTFE a high molecular weight that provides several advantages. For example, PTFE is water resistant and resistant to substances containing water. PTFE also resists friction against solid and is highly heat resistant.

This allows PTFE to be used as a component of gears, bearings, and slide plates. PTFE does not begin to degrade until it reaches a temperature of degrees Fahrenheit. These are mostly used for the insulation of wires and cables, tubing, pipe liners and films. PTFE powder can also be used as a powder coating for some materials, offering a more aesthetic finish. In combination with its extremely low surface tension, ISO-PTFE is a very suitable material for a variety of challenging applications in the chemical, pharmaceutical and food industries.

Bead blasting is often used in creating a uniform surface finish on machined parts. Dry bead blasting is primarily used on stainless steel finishing, for any type of fabrication and gives the metal a satin finish. Wet blasting, sometimes referred to as vapor blasting is the process for removing a coating layer e.

By creating a smooth surface, grit blasting removes the pits and cracks that frequently harbour moisture and contaminants. Due to its high etch properties, its ability to be recycled and its fast working speed, aluminium oxide is an extremely popular media that we offer in our grit blasting service. Dry ice blasting is an environmentally friendly coating removal solution which uses a solid form of carbon dioxide to strip unwanted paint, rust and other coating layers without damaging the surface material underneath.

Glass grit blasting is a low cost and low impact media, often used for vehicle and automotive part refurbishment. Plastic grit blasting is a plastic media often melamine that can be used for cleaning, coating stripping and deflashing purposes. Our pyrolysis burn off oven is an extremely effective solution for the removal of plastic or paint coatings and contaminants. Our coating removal processes ensure the integrity of the surface material is left undamaged, whilst removing rust, paint or any other unwanted coating.

PTFE Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene and is known for being one of the most versatile plastics available. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material, probably best-known for its non-stick properties. The key properties that Virgin PTFE is widely known for it's extreme chemical resistance, thermal stability, electrical insulation and it's very low coefficient of friction.

Glass fibre is used as a PTFE filler as it offers much improved compression and wear properties. Carbon filled PTFE provides good thermal conductivity, low permeability and is also electrically conductive.

Stainless Steel Filled PTFE is extremely hard wearing, has excellent strength and stability under extreme loads and elevated temperatures. O ur technical experts can quickly tell you what PTFE solution is best for your project. This guide explains the coating procedure from start to finish, as performed by our expert engineers. The versatility of Teflon coatings allows for almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent non-stick qualities.

Specifically developed for use at elevated temperatures and for prolonged use at elevated temperatures, AF retains its key physical properties to temperatures 30OC higher than standard AF Virgin PEEK. VICTREX PEEK has a wider range of processing options, is lighter and more durable than many metal counterparts, and as such makes an effective and cost efficient replacement for metals.

Through melt processing PCTFE resin can be modified to give different mechanical and optical properties by controlling the crystalinity of the material.

Our polyurethane materials range from shore A hardness 57 to 95 and are all Hydrolysis resistant — often referred to as H-PU. FEP coatings Fluorinated Ethylene Propylene Copolymer melt and flow during baking to provide smooth non-stick, non-porous films with excellent abrasion resistance. PFA Perfluoroalkoxy coatings melt and flow during baking to provide non-porous films and increased permeation resistance.

The resins within these coatings are the toughest within the fluoropolymer range and can be applied at film builds up to 1, micrometers. Find out more by getting in touch with us. PTFE is an integral part of our day to day applications. PTFE as an advanced engineering material has a variety of benefits. When it comes to manufacturing and engineering, it is used for handling and storing corrosive chemicals as well as coating parts such as bearings and screws.

Other added advantages include its lack of toxicity. It has only a minor contraindication for humans as a result of polymer fume fever. Otherwise it is FDA approved and food-safe.
