PTFE micropowder wax is a white micropowder resin. It is obtained by coagulation, washing and drying of the dispersion obtained by telomerization of tetrafluoroethylene. It has excellent heat resistance, weather resistance, cold resistance and low friction. , non-stick, chemical stability and electrical insulation properties and other excellent properties. In addition, due to its small average particle size, it has good dispersibility and is easy to blend with other materials uniformly.
Micronized wax PTFE is a white fluorine-containing additive with fluidity, which is formed by loosely agglomerating particles with submicron structure. It is usually used as a processing aid for plastics and rubber (elastomers), reducing the surface properties of materials, effectively improving the lubricity and wear resistance of materials, and having other properties of fluoropolymers.
It can be added to lubricants to improve performance stability in harsh environments, and can also be used alone as dry lubricants, but cannot be used to replace high molecular weight PTFE suspension or dispersion resins for extrusion and molding.
PTFE micronized wax is inert to almost all chemicals and solvents, does not absorb water, and has good electrical insulation and weather resistance.
Used as a processing aid for plastics and rubber (elastomers)
Improve its lubricity, reduce friction, wear and minimize surface defects of products during extrusion and injection molding.
Generally add 5%-20% by weight. Applicable materials include: polycarbonate (PC), polyamide (PA), polyester (PBT, PET, etc.), polyacetal (POM), polyimide (PI), polysulfone (PSU), etc.; rubber (Elastomers) include acrylates, fluoroelastomers, neoprene, nitrile and silicone.
Improve the lubricity and service life of lubricants, especially in high-viscosity lubricants under high pressure, high temperature, and corrosive environments, the effect is remarkable.
Addition to silicone, fluorosilicone and carbon compound based lubricants results in smooth, homogeneous suspensions using conventional blending methods.
PTFE for printing ink
Improves ink rub resistance, surface slip and gloss, and also reduces blocking.
The addition ratio is about 0.5-3% (weight ratio). Usually, PTFE micronized wax can be mixed with polyethylene wax to obtain better improvement effect. PTFE micropowder wax has small particle size and narrow distribution. It can also effectively improve non-stickiness, reduce friction, improve wear resistance, improve corrosion resistance and reduce wetting when used in coating systems.
