Characteristics and Applications of PEEK Plastic Material

The characteristics of PEEK plastic

PEEK is a highly processable organic semicrystalline thermoplastic material. Its polymer structure has excellent environmental resistance, dimensional stability, and mechanical strength. Some key performance characteristics of PEEK include:

PEEK plastic material is suitable for continuous temperatures up to 250℃ (483°F), or even higher for steam or high-pressure environments while maintaining rigidity. It can be used for high-pressure sterilization to increase hygiene and medical applications. When exposed to open flames, it has extremely low toxicity and gas emissions, enhancing safety in high-temperature environments. Suitable for use with ultra-high vacuum pumps. PEEK plastic materials have high quality strength and hardness, with excellent resistance to fragmentation.

PEEK plastic materials can be machined using electroplated diamond, polycrystalline diamond (PCD), or polished hard alloy cutting tools (PCD cutting tools are recommended for machining glass-filled PEEK). They have high resistance to chemicals, solvents, hydrolysis, seawater, and many other aqueous environments. Dissolves very slowly in concentrated acid solutions, such as high molar concentrations of nitric acid and sulfuric acid. PEEK plastic material is resistant to creep even at high temperatures.

PEEK plastic materials can be filled with glass or carbon fiber fillers to enhance physical properties, such as larger thermal stability and higher mechanical strength. They have low hygroscopicity, making them ideal for harsh environments and as high-strength substitutes for fluoropolymers. They are durable, wear-resistant, and have extremely long service life, even in harsh environments and applications with excessive wear. They are radiation-resistant and inherently flame-retardant.

What are the polyetheretherketone applications?

PEEK is used for heart shaft covers: 

PEEK can withstand extreme pressure, temperature, physical wear, and chemical exposure. These features make PEEK the preferred material for manufacturing heart shaft cover components.

Polyetheretherketone applications as a substitute for metal: 

Due to PEEK's superior strength-to-weight ratio, engineers can consider using PEEK to replace heavier metal components. PEEK can withstand mechanical and physical stress, as well as excellent chemical and thermal resistance, which together give it an advantage over metal parts. These qualities make polyetheretherketone suitable for general industrial environments, such as automotive and aerospace.

PEEK is applied to wire harnesses: 

PEEK protects and insulates wires, while improving fuel efficiency and reducing weight. PEEK corrugated pipes can be used as flexible conduits to collect wires and wire harnesses, making them easier to manage. PEEK tubing can also protect covered items from abrasion and physical trauma. In addition to its insulation and protection functions, polyetheretherketone can also be used to support wire splices. PEEK and PEEK wire harnesses are widely used in the aerospace and automotive industries and can easily adapt to many different fields.

Polyetheretherketone applications for wire splicing: 

PEEK provides excellent chemical resistance and electrical insulation; these properties make it a perfect splicing tool for both on-site repairs and design purposes.
