Quadrant Engineering Plastic Products' stock shapes made of crystalline thermoplastic polyester, are marketed under the trade names Ertalyte® (virgin grade) and Ertalyte TX® (bearing grade).
Ertalyte (colours: natural [white], black) is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). The specific properties of Ertalyte virgin crystalline PET make it especially suitable for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.
Ertalyte natural (rods, plates) is available as a "Food Grade".
Ertalyte is FDA compliant in natural color and on request also in black. Natural colored Ertalyte® is also 3A-Dairy compliant. The material is an excellent candidate for parts used in the food processing and equipment industries.
Process and test equipment manifolds machined from Ertalyte offer improved dimensional stability combined with superior stain and chemical resistance. (Prior materials: Aluminum, Acetal)
Many parts on food manufacturing and processing equipment are machined from Ertalyte — like this hamburger forming die component which meets stringent tolerance requirements and can be easily sanitized using clean-in-place chemicals. (Prior material: Aluminum)
Its rigidity and clean hygienic appearance — in addition to dimensional stability and resistance to dilute hydrochloric acid-made Ertalyte the ideal choice for various components on pharmaceutical test equipment. (Prior material: Nylon, UHMW-PE)
Ertalyte TX (colour: pale-grey) is a polyethylene terephthalate compound incorporating a uniformly dispersed solid lubricant. Its specific formulation makes it a premium internally lubricated bearing-grade. Ertalyte TX not only has an outstanding wear resistance, but offers in comparison with Ertalyte an even lower coefficient of friction as well as higher pressure-velocity capabilities.
Ertalyte TX excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces.
Ertalyte TX is available in various shapes as a "Food Grade". It is also FDA, USDA and 3A-Dairy compliant.
Ertalyte® TX excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces. The distribution valves in this food packing machinery are made of Ketron® PEEK-1000 and Ertalyte TX. These materials are replacing stainless steel parts which caused too much wear of the housing and consequently unacceptable maintenance costs. The clearance between distribution shaft and housing must be kept as tight as possible to avoid leakage. (Prior material: Stainless Steel)
Ertalyte® - Where Material and Solutions Innovation Meet
Because it is more rigid and offers greater thermal performance than Nylon and Acetal, Ertalyte machines differently. For best results, please consult us for machining details.
