Poly (ether ether ketone)(PEEK) is a linear polymer whose main chain is composed of Aryl, ketone and ether bonds. PEEK has a large number of benzene rings in its molecular chain, so its heat resistance can match that of polyimide, while two ether chains and a renegade group provide the material with flexibility and excellent workmanship.The structure is as follows:


High Temperature PerformanceSuitable for continuous-use temperatures up to 260°C (500°F). Glass transition temperatures up to 143°C (289.4°F).
High Wear ResistanceLow coefficient of friction. High abrasion and cut-through resistance.
Mechanical Strength and Dimensional StabilityHigh strength and stiffness in demanding conditions. Excellent long-term creep and fatigue properties.
Resistance to Harsh ChemicalsWithstands a wide range of acids and bases and shows excellent performance in hydrocarbons and organic solvents.
High Electrical IntegrityMaintains stable electrical performance even in high-temperature or humid environments, suitable for insulation components.
High Purity & Bio-inertComplies with industrial purity standards, non-toxic and non-reactive with biological substances, ideal for food-contact or medical-related applications.

We started the PEEK polymerization project in 2014 and completed the pilot test in 2016. In 2018, Shandong Junhao HPP Co., Ltd. was officially established in Jining, Shandong Province, China, to carry out industrial production of PEEK polymerization, and finally in 2019, we complete the production of PEEK industrial chain.

Blending modification is the most commonly used method for modifying PEEK materials. Typically, fibers, metal oxides, inorganic fillers, and high-molecular polymers (such as PTFE) can be added to the raw materials.The PEEK composite material prepared by this method can improve the defects of PEEK by using the composite effect, and improve the comprehensive properties of the material to a great extent.
The addition of PTFE, graphite and carbon fibre makes PEEK5600LF30 a bearing grade plastic. Its superior friction properties (low coefficient of friction, wear resistance, high peak pressure limit) make this grade an ideal material for friction applications. It is suitable for the manufacture of wear strips, friction discs and other products.
According to the liquidity, it can be subdivided into: PEEK3600LF30; PEEK5600LF30.PEEK3600GF30 is a high mobility PEEK particle.

Most standard reciprocating screw injection moulding machines are capable of moulding unfilled and filled PEEK grades. Complex and intricate high performance components can be mass-produced without annealing or conventional machining. technical experts can assist with design and process variables such as machine design, barrel capacity, screw and mold design and gating.
PEEK thermoplastics can be used in extrusion processes and equipment including wire coating, profile extrusion, film, pipe, sheet and monofilament production. Unfilled and filled grades are readily extruded using conventional melt processing technology. Our highly experienced technical team can help define the machine design and address any processing challenges.
Compression moulded parts are generally more crystalline, have a higher modulus and tensile strength and are harder with a lower ductility. Glass and carbon fibres may be combined with PEEK for compression moulding. Our technical team recommends that our customers anneal parts with very thick sections to relieve stresses.
