Ertalyte® is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by Mitsubishi Chemical Advanced Materials. Only Mitsubishi Chemical Advanced Materials can offer Ertalyte®. It is characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte®'s properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. Ertalyte®'s continuous service temperature is 210°F (100°C) and its melting point is almost 150°F higher than acetals. It retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal (See Figure 9).
In addition, Ertalyte® PET-P offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture (See Figure 11). Ertalyte® PET-P can be machined to precise detail on standard metal working equipment.
Ertalyte® 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 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. Ertalyte® TX 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)
Because it is more rigid and offers greater thermal performance than nylon and acetal, Ertalyte machines differently. For best results, please request a copy of Mitsubishi Chemical Advanced Materials's design and fabrication guideline for Ertalyte® PET-P. Ertalyte® and other polyesters have less resistance to hot water than Acetron® GP acetal.
