Wear resistance of PTFE wax in UV

2021-05-13   Pageview:351

PTFE wax is also known as PTFE micropowder, white, fine particles, prepared from low molecular weight PTFE, mainly used as an additive in plastics, inks, coatings, to improve the non-stick and wear resistance of the substrate material.

The molecular weight of micronized powder is generally one percent of that of high molecular weight PTFE. The lower molecular weight also means that micronized powder is not suitable for the molding and sintering process of high molecular weight PTFE, because the products made from it do not have strength.

Low molecular weight tetrafluoroethylene can be mixed well with the base material, thus giving the base material certain characteristics of tetrafluoroethylene. High molecular weight tetrafluoroethylene is fibrous and the particles are not easily broken, so it cannot be used as an additive.

After adding PTFE wax powder, the properties of the base material will be changed.

1, In thermoplastics, elastomers and thermosets, it can improve the wear resistance, non-stick and reduce the surface friction coefficient.

2, In grease, the lubricity and fast lubrication are enhanced, especially in high temperature and high load.

3, In ink,  it can help to improve the surface gloss, increase wear resistance and reduce blockage.

4, In the non-stick coating and wear-resistant coating, it can improve the non-stick property of the coating, reduce the friction coefficient, improve the corrosion resistance and wear resistance.

The PTFE micropowder produced by Nanjing Tanshi is suitable to be added to various engineering plastics, non-stick coatings, coil steel coatings, powder coatings, inks, lubricants and greases. PTFE micropowder as an additive of elastomer makes the base material have good demoulding performance, improve the abrasion resistance of the material, reduce the surface friction coefficient of the material, and improve the bending strength.
