PEEK (polyetheretherketone) polymers and their composite high-performance plastics have been widely used in high-temperature, corrosion-resistant, self-lubricating, wear-resistant, high-strength, high-dimensional In chromatographic columns, chromatographic analysis, chromatographic preparation, flow path fluids, liquid sealing and other related equipment. Comparative analysis of PEEK board and PEI board in terms of performance ●Physical aspect: the specific gravity of PEEK and PEI is close, both are between 1.3-1.35, the conventional color: peek is beige; PEI is amber. ●Temperature resistance: the long-term temperature resistance of PEEK board is 260 degrees, and the instantaneous working temperature is 300 degrees; the long-term operating temperature of PEI board is 170 degrees, and the short-term operating temperature is 200 degrees. ●Glass transition temperature: The glass transition temperature of PEEK is 146 degrees, and the heat distortion temperature is 310 degrees; the glass transition temperature of PEI is 216 degrees, and the heat distortion temperature is 238 degrees; ●In terms of flame resistance coefficient: PEEK and PEI are both UL94-VO grades, and both have good flame retardant effect. Compared with PEI, PEEK has better flame retardant effect. The above is the information about PEI. If you want to know more news and trends, you can click on our official website.
