Dupont PTFE 641XT X Polytetrafluoroethylene PTFE Virgin Resin Pellet Powder IN STOCK

Teflon™ is a registered trademark of Chemours for its fluoropolymer resins. Teflon™ PTFE fluoropolymer resins are part of the family of fluorine-based products that also include Teflon™ FEP and Teflon™ PFA and Tefzel™ fluoropolymer resins.

Teflon™ PTFE 640XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion, offering an excellent combination of properties:

• Non-aging characteristics
• Chemical inertness to nearly all industrial chemicals and solvents
• Exceptional dielectric properties, stable with frequency and temperature
• Toughness and flexibility
• Low coefficient of friction
• Non-stick characteristics
• Negligible moisture absorption
• Excellent weather resistance
• Service temperature up to 260°C (500°F)
• Useful properties at -240°C (-400°F)

Teflon™ PTFE 640XT X is designed for processing over a wide extrusion reduction ratio range (250:1-5000:1), with excellent performance even at the top of this range. Due to its outstanding transformation characteristics, it can be extruded with very low lubricant levels over a wide reduction ratio range while maintaining low extrusion pressure.

This material can be extruded into wire with excellent performance in the reduction ratio range of 1000:1-4500:1 with a single lubricant level of 16% (based on total weight), allowing a single PTFE/lubricant mixture to be used for many constructions manufactured in the same size extruder line.
