- High maximum allowable service temperature in air (170°C continuously)
- Very good hydrolysis resistance (suitable for repeated steam sterilization)
- High strength and stiffness over a wide temperature range
- Inherent low flammability and low levels of smoke evolution during combustion
- Good dimensional stability
- Physiologically inert (suitable for food contact)
- Very good resistance against high energy radiation (gamma- and X-rays)
- Very good electrical insulating and dielectric properties
Duratron U1000 PEI is extremely suitable for electrical / electronic insulators (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures. Thanks to its good hydrolysis resistance Duratron U1000 PEI is capable of withstanding repeated autoclaving cycles.
Duratron® LSG PEI
Duratron LSG PEI stock shapes are produced from selected batches of a specific Ultem polyetherimide resin. This polymer shows a combination of outstanding mechanical, thermal and electrical properties combined with a good hydrolysis and chemical resistance. The composition of the resin used for the production of the Duratron LSG PEI stock shapes complies with the regulations that apply in the Member States of the European Union (Directive 2002/72/EC, as amended) and in the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs. Duratron LSG PEI stock shapes have also been successfully type tested for their compliance with both United States Pharmacopeia (USP) and ISO 10993-1 guideline requirements for Biocompatibility Testing of Materials, and they come with full traceability from resin to stock shape. These features, added to a very good sterilizability by means of steam, dry heat, ethylene oxide, plasma and gamma irradiation, make Duratron LSG PEI stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.
