Following the successful launch of the PEEK series products, Zhejiang Conceptfe New Material Technology Co., Ltd. has successfully introduced another special engineering plastic - polyvinylidene fluoride (PVDF), which ranks second in production among fluorine-containing plastics.

Polyetheretherketone, abbreviated as PEEK, belongs to aromatic high - molecular compounds. Together with polyetherketone (PEK), polyetherketoneketone (PEKK), polyetheretherketoneketone (PEEKK), and polyetherketoneetherketoneketone (PEKEKK), they are collectively referred to as polyaryletherketone (PAEK).
