PETP
The specific properties of this virgin crystalline PET make it specially suitable for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.
Profile
- High mechanical strength, stiffness and hardness
- Very good creep resistance
- Low and constant coefficient of friction
- Excellent wear resistance (comparable with or even better than nylon grades)
- Very good dimensional stability (better than polyacetal)
- Excellent stain resistance
- Better resistance to acids than nylon and polyacetal
- Good electrical insulating properties
- Physiologically inert (suitable for food contact)
- Good resistance to high energy radiation (gamma and X-rays)
Applications
- Manifolds
- Process and test equipment manifolds machined from Ertalyte offer improved dimensional stability combined with superior stain and chemical resistance.
- Food Equipment Components
- Many parts of 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.
- Carousel, Filter Track, Locating Disk and Ring
- 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 pharmceutical test equipment.
- Distribution Valves
- Ertalyte 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.
