Poly-ether-ether-ketone (English poly-ether-ether-ketone, PEEK for short) is a polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure. It is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a semi-crystalline polymer material with a melting point of 343°C, a softening point of 168°C, and a tensile strength of 132～148MPa. It can be used as high temperature resistant structural materials and electrical insulating materials. Composite with glass fiber or carbon fiber to prepare reinforced material. Generally, a type of polyarylether polymer obtained by condensation with aromatic dihydric phenol is used. This material has a large number of applications in the aerospace field, the field (as an artificial bone to repair bone defects) and the industrial field.

It is resistant to hot water, alkalis, acids, oils, but is easily corroded by halogenated hydrocarbons, has poor hydrolysis resistance, can crystallize rapidly at low temperatures, and has good moldability. Relying on the plasticity of synthetic resins, various functions are introduced into modified plastics through formulation technology, and the additives corresponding to various functions have also formed a consensus in the industry. The selection of additives has almost become a standardized behavior. 3. Plastics: 1. Appropriate additives and agents should be used for plastics with poor fluidity or heat sensitivity. 2. Nylon is a polyamide and has it in its main chain. The key requirement is its ability to physically or chemically bond with the matrix polymer to strengthen the toughness of the plastic.
