Fluoroplastic PTFE MICROPOWDER

PTFE MICROPOWDER MV3

Get to Know PTFE MV3

Everflon™ PTFE MV3 fluoroadditive is a white, free-flowing, PTFE powder designed for use as an additive in other materials or as a dry lubricant. It can be used at temperatures from –190 °C to 250 °C (–310 °F to 480 °F), and is inert to nearly all industrial chemicals and solvents. It is a good electrical insulator, does not absorb water, and is highly resistant to weathering.

• Low surface energy

• Improved lubricity and wear in plastics and elastomers

• Improved performance in lubricants under severe conditions

• Improved nonstick and antifriction properties

Typical Applications

It can be added at up to 30% by weight to base elastomers to improve abrasion resistance and lower the coefficient of friction. At 1-3% by weight, it is an excellent slip enhancer for a variety of water and solvent based inks. It can also be added to plastics, such as polyacetals,polyamides, polycarbonates, polyesters, polyimides, polysulfides, and polysulfones, at 5-20% by weight to reduce friction and wear.

• Provides anti-stick surfaces

• Reduces friction and wear in parts

• Reduces plate-out

• Increases lubrication

• Provides improvements in corrosion inhibition

• Reduces wettability

• Reduces “blocking” in inks

• Improves gloss and surface smoothness

Processing Guide

Heating Everflon™ PTFE in excess of 399 °C (750 °F) can produce toxic fumes. It is, therefore, necessary to provide local exhaust ventilation in areas where Everflon™ PTFE products are exposed to high temperatures. Avoid breathing fumes or contaminating smoking tobacco with fumes, powder, or dust.

Thermal decomposition of this product will generate hydrogen fluoride, which is corrosive. Corrosion resistant materials are required for prolonged contact with molten resin.

Precaution

Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to completely remove all fumes and vapors from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before processing any fluoroplastics, read the Material Safety Data Sheet.
