What is ultrafine PTFE?

Ultra-fine polytetrafluoroethylene (PTFE) powder is a white, low-molecular-weight, free-flowing powder with stable molecular structure, excellent chemical resistance (resistance to strong acids and alkalis), good electrical insulation, and extremely high flame retardancy Performance, excellent self-lubricity, high weather resistance, aging resistance, good UV resistance, scratch resistance, scratch resistance, good hand feeling, good gloss, good thermal stability, wide temperature range ( -200- +300), and has good non-stick properties and recoatability. After the special surface treatment, the polytetrafluoroethylene (PTFE) powder not only maintains the original excellent properties of PTFE, but also has many unique properties: such as good dispersibility, good compatibility, no self-aggregation, no static electricity Effectiveness, high self-lubricity, reduced friction coefficient, etc.

Due to its high hardness, ultra-fine powder PTFE has excellent scratch resistance and antiabrasion properties. Resistance to metal scratching.

Use of ultrafine PTFE Powder

Useful in various solvent-based paints and powders. Plastic coatings are also suitable for use. It can be used as a solid instead of liquid lubricant. You can use it to improve the fluidity in the ink. It is typically added at a rate of 1-3wt% as an anti-wear agent. The coating can also be non-stick. The amount of addition is usually not more than 5wt%. The organic solvent can be dispersed as a release agent. It can also act as a highly effective anti-drip agent for various plastics, such as the environmentally friendly flame retardants polycarbonate (PC), Polyurethane(PU) and polystyrene(PS).

The recommended dosage ranges from 0.1-5.0%. The additive is added to the process at the very beginning. For the best results, it is necessary to stir at high speed. To avoid affecting its performance, it is best to not use a sand or three-rolls mill. If needed, the organic solvent can be pre-dispersed and added to the slurry.
