PEEK5600G
PEEK5600G is one of unfilled or natural PEEK. Outstanding chemical resistance and a high operating temperature (up to 250℃/480F) round out PEEK profile. PEEK5600G has excellent dimensional stability combined with high creep stability, ensuring the suitability of PEEK for the most sophisticated machined parts.
OVERVIEW
PEEK5600G is the most commonly used brand in the world, it is medium fluidity PEEK pure material particles, and its corresponding is VICTREX PEEK 450G.
What is PEEK？
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：
Advantages

PEEK Manufacturing Plant
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.
PEEK Material and Types of Its Modification
UNFILLED PEEK has excellent physical and chemical properties in its own right. Its characteristics of high strength, high toughness, corrosion resistance, high temperature resistance, good insulation, high purity basically meet most of the industrial environment.
PEEK3600G is a high mobility pure PEEK particle, and PEEK7600G is a low mobility pure PEEK particle.

Process with Ease When Specifying PEEK High-Performance Polymers
PEEK polymer is capable of being processed on conventional thermoplastic equipment. Unfilled and filled grades may be supplied in the form of granules, powder or ultra-fine powder. Granules are generally recommended for injection moulding, extrusion, monofilament and wire coating operations. Powder is used for compression moulding whilst fine powders are generally used for coating processes and composite pre-preg manufacture.
Injection Moulding
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.
Extrusion
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 Molding
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.
