Web rows · Jan 2,  · PEEK plastic is a high-performance material with excellent mechanical strength, lightweight, and. Compatibility was then classified into A, B, or C which should be interpreted as follows: A – No interaction. Victrex materials are likely to operate in these. Begin Compatibility Search: CHEMICAL TO MATERIAL. CHEMICAL TO CHEMICAL. Use dropdowns below to select a Chemical, and compare against ALL MATERIALS or any. WebPEEK has much higher temperature performance, wear resistance, chemicals resistance and fatigue performance as compared to PES; PEEK is not normally blended with other polymers. However, it forms miscible blends with a range of other polyketones and PEI. PEEK/PEI blends have higher Tg. And, its blends with PES and PPS are highly compatible.

WebSterilization with hydrogen peroxide plasma is suitable for all plastics, however, it is costly and requires elaborate equipment. Highly reactive hydroxy and hydroxyl radicals kill the microorganisms at temperatures of just °F over periods of 45 to 80 minutes; the plasma is removed by ventilation. WebJun 1,  · Hydrogen bonding and mechanical interlocking enhanced interface adhesion, and covalent bonds of HPEEK-g-MWCNT increased load transfer. It has excellent compatibility with PEEK because of its similar structure to PEEK, satisfying “similar dissolve mutually theory” [22]. Katti [23] used HPEEK grafted graphene oxide as a filler . WebPEEK is compatible with almost any of the solvents used in HPLC. The only solvents which will attack PEEK are concentrated nitric acid and sulphuric acids. However, PEEK tubing . WebHydrogen Peroxide Material Compatibility Chart All wetted surfaces should be made of materials that are compatible with hydrogen peroxide. The wetted area or surface of a part, component, vessel or piping is a surface which is in permanent contact with or is permanently exposed to the process fluid (liquid or gas).
