Description

PTFE Micropowders (Polytetrafluoroethylene Micropowders) are refined, low–molecular-weight PTFE materials primarily used in non-fluoropolymer industries. When incorporated into other products, they provide fluoropolymer-like characteristics that enhance overall performance. Except for their use as dry-film lubricants, PTFE micropowders are seldom used independently.

Material Advantages

Enhanced Lubricity & Reduced Friction

• Increases wear and corrosion resistance in engineering plastics.

• Forms an in-situ PTFE film on screw and barrel surfaces to reduce material flow resistance.

• Enhances processing efficiency of commodity plastics.

Multifunctional Performance Improvements

• Contributes to better product durability and stability.

Surface Property Enhancements

• Improves smoothness, gloss, and anti-scratch properties.

Operational Benefits

• Provides better processing behavior and improved mold release performance.

Application Fields

Paint Industry

• Improves non-stick properties and reduces friction.

• Enhances wear resistance, surface texture, brightness, and scratch resistance.

• Provides better corrosion resistance and reduces infiltration.

Engineering Rubber & Plastics Industry

• Reduces friction coefficient and enhances lubricity and wear resistance.

• Improves dispersion during processing and facilitates mold release.

• Can be blended with flame retardants to prevent dripping.

• Offers improved aging resistance.

Ink & Grease Industry

• Improves friction resistance, surface smoothness, and gloss on printed materials.

• Reduces blocking issues.
