Some of the reasons PTFE or polytetrafluoroethylene finds its use in varied applications are because of its low friction, excellent electrical resistance, high chemical resistance, non stick properties and unreactivity. In the following sections we will have more detailed look at its properties and applications it is used in.

Features of PTFE

One of the features of PTFE is that it is hydrophobic which means it does not get wet by water or any type of substance which contains water.

Additionally, it has very low co-efficient of friction which means it can provide a very slippery surface to be utilized in different applications.

Any PTFE bush manufacturer in India favors use of PTFE over other material since it has less friction which also makes it ideal for use as lubricant for reducing friction, energy consumption and wear of machinery.

The other advantage of PTFE is that it has very high melting point of 600k and is able to maintain its toughness, strength as well as self lubrication in low temperatures up to 5k.

Applications of PTFE

Electrical Wiring

One of the applications it is put to use is in wiring which is used in computer applications and aerospace. This is made possible by high dielectric properties PTFE has. It is also utilized as insulator for connector assemblies as well as for cables.

Low Friction

Its low friction features make is useful for applications in which sliding action is important for parts. Some examples include its use in gears, plain bearings and slide plates.

Such friction less properties also aid in facilitating better flow of viscous liquids and also finds its use in brake hoses.

Use in Aerospace Industry

In aerospace industry it is used for producing fiberglass composites as well as fiber composites. PTFE films are also utilized as barrier in-between fiberglass and carbon part which is being built.

Such films help in preventing non production substances from sticking onto parts which are being built.

Non Re-activity

PTFE has superior non-reactivity as well as very good high temperature rating which makes it ideal for use in expansion joints, hose assemblies as well as in case of industrial pipelines where alkalies and acids are transported through pipelines.

Any ptfe bush manufacturer prefers PTFE for such non-reactivity and also makes it suitable for use in industries such as brewery, pharmaceutical, dairy and food.

Use in Fabrics

It can be used for manufacturing breathable as well as waterproof fabric to be used in outdoor apparel. In addition to it, it is also utilized in the form of fabric protector for repelling stains on school wear such as uniform blazers.

Medical and Sports Applications

When utilized as film interface patch, it features adhesive backing which is pressure sensitive and can be utilized in very strategic locations which face high friction such as the insoles and footwear. It is also used in medical devices for preventing friction induced calluses and blisters.

In case you are searching for a ptfe bush manufacturer then you should get in touch with Solptfe. They have the required experience and expertise to service any requirement you may have and fully meet your expectations of quality and pricing.
