1000 PEEK- Nhựa chịu va đập tốt nhất
Ketron 1000 PEEK stock shapes are produced from virgin polyetheretherketone resin and offer the highest toughness and impact strength of all Ketron PEEK grades. Both Ketron 1000 PEEK natural & black can be sterilized by all conventional sterilization methods (steam, dry heat, ethylene oxide and gamma irradiation). Additionally, the composition of the raw materials used for the manufacture of Ketron 1000 PEEK stock shapes complies with the regulations of the European Union (Directive 2002/72/EC, as amended) and the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs.
Ketron 1000 PEEK natural and black (rods, plates, tubes) are available as "Food Grades".
PRODUCT OVERVIEW.
- Very high maximum allowable service temperature in air (250 °C continuously, up to 310 °C for short periods of time)
- High mechanical strength, stiffness and creep resistance, also at elevated temperatures
- Excellent chemical and hydrolysis resistance
- Excellent wear & frictional behaviour
- Very good dimensional stability
- Excellent resistance to high energy radiation (gamma- and X-rays)
- Inherent low flammability and very low levels of smoke evolution during combustion
ENGINEERING NOTES
The stiffness of all PEEK grades drops off significantly and expansion rate increases above its glass transition temperature (Tg) of 150 °C (300 °F). A material like Duratron® PAI would be better suited for close tolerance bearings or seals operating at temperatures higher than 150 °C (300 °F).
