China KETASPIRE PEEK Manufacturer, Supplier, Factory

Visa Plastics is KETASPIRE PEEK manufacturer and supplier in China who can wholesale KETASPIRE PEEK. KetaSpire® polyetheretherketone (PEEK) is considered one of the highest performing, semi-crystalline thermoplastics available today. PEEK offers a combination of superlative properties that allow KetaSpire® PEEK to effectively replace metal in some of the most severe end-use environments.

KetaSpire® PEEK is produced using nucleophilic displacement chemistry with hydroquinone and 4,4 ’-difluorobenzophenone. The structure of the repeating unit is shown in Figure 1.1.
