Teflon™ PTFE NXT 85
Modified Granular Fluoroplastic Resin

Product Information
Description• Bearing pad

Teflon PTFE NXT 85 is a free-flowing, pelletized, chemicallymodified granular resin (its equivalent fine-cut resin is Teflon™
NXT 75). It provides superior processing characteristics inaddition to properties of chemically modified resins. When
properly processed, it offers an excellent combination ofproperties that are characteristic of Teflon™ fluoroplastic
resins:• Electrical insulation™

• Chemical inertness• Exceptional dielectric properties• Heat resistance• Toughness and flexibility• Low coefficient of friction• Non-stick characteristics• Negligible water absorption• Excellent weather resistanceThis resin is particularly useful in applications where weldingof parts to other fluoropolymers such as PFA or standard
PTFE is required, e.g., fluid handling systems.

Processing
Teflon™ PTFE NXT 85 can be processed by all methods used
for conversion of free-flow granular PTFE resins to parts.
Traditional billet and sheet molding techniques can be used toproduce large shapes. More complex parts can be fabricatedby automatic and isostatic molding methods. This resin canalso be converted to rods and tubes by ram extrusion. All
molding methods, except ram extrusion, produce preforms
that must be sintered in ovens. Finished product properties
depend on preform pressure and the sintering cycle. The
sintering cycle is defined by temperature, time, and thecooling rate. Typical properties are listed in Table 1.

This chemically modified resin offers improved resistance todeformation under load, increased resistance to permeationof chemicals, and higher dielectric breakdown strength.
Teflon™ PTFE NXT 85 provides a high degree of weldability
for applications where the use of elevated temperature andpressure are limited.

Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ PTFE NXT 85
resin can qualify for use in contact with food in compliancewith FDA Regulation 21 CFR 177.1550.

Typical Applications

Safety Precautions

Teflon PTFE NXT 85 can be converted to parts by isostatic,
billet, and sheet molding methods, as well as ram extrusion. It
can be used for:

Storage and Handlingtemperatures cause even very small foreign particles tobecome visible in finished moldings. Keep resin drums
closed and clean. Good housekeeping and careful handlingare essential.

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 setaccordingly.
Cleanliness is a critical requirement for successful use ofTeflon™ PTFE NXT 85. The white resin and high sinteringPackaging
Teflon™ PTFE NXT 85 is packaged in 45-kg (100-lb) drums.
Each drum has a bag liner made of polyethylene resin.
