PEEK is a high-performance engineering plastic with outstanding resistance to harsh chemicals and excellent mechanical strength and dimensional stability. PEEK polymer provides exceptional performance over a wide range of temperatures and extreme conditions.

It provides a unique combination and range of high-performance properties. PEEK polymers have prompted advances across industries such aerospace, oil and gas, semiconductor, medical field, food and many others.

Yasojima Proceed is a licenced Victrex PEEK supplier.

Unique combination of properties

High temperatures resistance

Can be adapted to work at 260℃, and can also work continuously and have a melting point around 343°C.
UL 94 V-0 flammability rating
(0.059″ thickness)

Wear resistance and lubricity

Excellent wear resistance with some PEEK having extremely low coefficients of friction and wear.
