Properties and Uses of Ultrafine PTFE Powder |

What does ultrafine PTFE powder mean?

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.

Enhance surface smoothness and gloss; improve product processing efficiency, reduce friction coefficient, increase product surface oiling. The ultra-fine, hard PTFE powder has excellent scratch resistance and anti-abrasion properties. It is resistant to metallic scratches. Technical index. Item Index parameter. 99.9% Bulk densitivity (kg/L). 0.5 Appearance. Liquid white powder. Average particle size (um) 2-5um. Melting point (?) >=326

Use ultrafine PTFE pulver

Useful in many solvent-based and powder coats including plastic coatings, paper paint, coils, wax coatings, oil-curable coatings, paints and light-curable coatings. It is also used to enhance the product’s mold release performance and surface scratch resistance. The PTFE powder is a good solid lubricant that can also be used as an oil lubricant. It is also useful to enhance the fluidity and performance of inks. It’s usually used in the amount of 1-3wt% as an anti-wear agent. You can use it for coatings that are nonstick. The normal addition level is 5wt%. You can use the organic solvent dispersion as a release agents. The organic solvent dispersion can be utilized as an effective anti-drip agent in a variety of plastics like polycarbonate, polyurethane and polystyrene.


A recommended dose is between 0.1 and 5.0%. The product is started with it. To achieve maximum dispersion, you need to stir at high speed. You should not place the product in a sandmill or three-roll mill as this will affect its performance. You can pre-disperse it with an organic solvent to give it a better result.
