Teflon™ PTFE NXT 75
Modified Granular Fluoroplastic Resin

Product Information
DescriptionProcessing

Teflon PTFE NXT 75 is a chemically modified PTFE polymer.
When properly processed, it offers an excellent combinationof properties that are characteristic of Teflon™ fluoroplastic
resins:Teflon™ NXT 75 may be converted by compression molding
techniques. A preform made at room temperature at
the recommended pressure of 14 MPa (2,000 psi) can
subsequently be sintered. Refer to the typical property data
in Table 1.

™

• Chemical inertness• Exceptional dielectric properties• Heat resistance• Toughness and flexibility• Low coefficient of friction

Of particular significance for sheet molding is the factthat maximum density after sintering is reached at lower
pressures when compared with non-modified granular grades
as shown in Figure 1. This allows for the production of larger
sheets with existing equipment.

• Non-stick characteristics• Excellent weather resistanceIn addition, this resin offers improved resistance todeformation under load, increased resistance to permeationof chemicals, and a higher dielectric breakdown voltage. Italso provides a high degree of weldability for applications
where the use of elevated pressure and temperature arelimited.

Typical Applications
Teflon™ NXT 75 is a fine-cut resin designed for generalcompression molding of blocks and sheets. It can be used for:• Seal rings• Valve seats• Bearing pads
• Linings
It can also be used as a base resin for filled compounds.
Teflon™ PTFE NXT 75 is particularly useful in applications
where welding of parts to other fluoroplastics such as PFA or
standard PTFE is required, e.g., fluid-handling systems.

Food Contact Compliance

Storage and Handling

Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ NXT 75 resin canqualify for use in contact with food in compliance with FDA
Regulation 21 CFR 177.1550.

Preforming is easiest when the resin is between 21–27 °C(70–80 °F). As temperature declines below this range, theresin will be increasingly difficult to mold without cracks andproblems with condensed moisture. Higher temperatures
inhibit flow and promote lumping. Storage conditions should
be set accordingly.

Safety Precautions
Before processing any fluoroplastics, read the Material
Safety Data Sheet, available upon request from ourCustomer Service Group at (844) 773-CHEM/2436 in theU.S. or (302) 773-1000 outside of the U.S. Also read thedetailed information in the latest edition of the “Guide tothe Safe Handling of Fluoropolymer Resins,” published by
the Fluoropolymers Division of The Society of the Plastics
Industry (www.fluoropolymers.org) or by PlasticsEurope(www.plasticseurope.org).

Cleanliness is a critical requirement for successful useof Teflon™ NXT 75. The white resin and high sintering
temperatures cause even very small foreign particles tobecome visible in finished moldings.
Keep resin drums closed and clean. Good housekeeping andcareful handling are essential.

Packaging
Teflon™ NXT 75 is packaged in 40-kg (88-lb) drums. Eachdrum has a bag liner made of polyethylene resin.
