Ertalyte® TX Sheet
Ertalyte® TX (Polyester-semi-crystalline thermoplastic with lubricant, extruded)-manufactured by Quadrant Engineering Plastic Products from proprietary resin grades, is an internally lubricated thermoplastic polyester providing enhanced wear and inertness over general purpose nylon (PA) and acetal (POM) products. Containing uniformly dispersed solid lubricant, Ertalyte® TX provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT, and even internally lubricated materials like Delrin® AF Blend.
Ertalyte® TX excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces and is FDA compliant.
Only Quadrant Engineering Plastic Products offers brand-name Ertalyte® TX stock shapes.
Other attributes of Ertalyte® TX products include:
Outstanding wear resistance
High LPV
Low and constant coefficient of friction (low slip stick)
Low moisture absorption -good for both wet and dry environments
High strength, stiffness, rigidity
Excellent resistance to stains
Excellent dimensional stability
Better resistance to acids than nylon or acetal
Closer tolerances and maximum straightness
