GENERAL PROPERTIES
PEEK HT ™ is a new unique high performance materials developed for applications that demand superior high temperature resistance. With a glass transition temperature of 315°F (157°C) and a melting temperature of 705°F (374°C), PEEK HT ™ delivers extended high temperature performance while offering all the key characteristics of natural PEEK ™ PolyEtherEther-Ketone polymer, including toughness, strength, and chemical resistance.
Across a wide range of demanding industrial, automotive and aerospace applications, PEEK HT ™ polymer offers manufacturers a premium material which is a more cost-effective, lightweight alternative to metals. From engine compartment applications to sub-sea connectors and heat exchanger parts, this advanced engineering material provides unlimited design freedom, high precision reproducibility and long-term product reliability.
PEEK HT ™ is available in Natural color (a very light brown or tan) in rod form only (3/4 to 2 inch diameters).
FEATURES • Superior high temperature performance
- retention of mechanical and physical properties to temperatures 54°F (30°C) higher than standard PEEK
- up to 3 times the wear resistance of standard PEEK at high temperatures
- long-term creep and fatigue resistance over a wide temperature range
- substantially higher tensile strength and flexural modulus at 482°F (250°C)
• Improved compressive strength
• Exceptional resistance to chemicals, solvents, fuels
• Inherent low flammability, low smoke emission
• Good electrical properties
• Excellent hydrolysis resistance
