PEEK-JUNDE HPP Co., Ltd

OVERVIEW

The most commonly used carbon fiber filled peek content is 30%. The name of this material is PEEK5600CF30. Compared with PEEK unfilled, the PEEK material filled with carbon fiber can improve higher hardness, strength, better heat resistance and friction characteristics. The modified peek filled with carbon fiber can be increased from 160 ℃ to over 300℃. Compared with this, the disadvantages of its carbon fiber modification are that it is more difficult to process, and the toughness is reduced. At the same time, due to the addition of carbon fiber, it has conductive characteristics.

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：

PEEK Material and Types of Its Modification

lending modification is usually the most commonly used modification method for PEEK materials. Generally, fibers, metal oxides, inorganic fillers and other 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.

According to the liquidity, it can be subdivided into: PEEK3600CF30; PEEK5600CF30; PEEK7600CF30. PEEK3600CF30 is a high mobility pure PEEK particle, and PEEK7600CF30 is a low mobility 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
Extrusion
Compression Molding

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.
