The advantages and disadvantages of the PEEK material

Polyether ether ketone (PEEK) is a high-temperature, high-performance thermoplastic special engineering plastics. It has good mechanical properties and resistance to chemicals, resistance to abrasion, resistance to hydrolysis and other properties; its light weight, self-lubricating properties, and having a very good flow properties and processing properties, can be filled with carbon fiber, graphite, molybdenum disulfide, etc. to further improve the lubricating properties and mechanical strength.
The superior performance of the PEEK material is mainly manifested in the following aspects:
1. high temperature: the PEEK product having a higher glass transition temperature (143 ° C) and melting point (334 ° C) This is one of the reasons that it can heat resistance requirements in the use of reliable applications. Load heat distortion temperature up to 316 ° C continuous use temperature of 260 ° C.
2. Mechanical properties: PEEK plastic toughness and rigidity, and to strike a balance. Especially its alternating stress of excellent fatigue resistance is the most outstanding in all plastic, can be comparable with alloys.
3.Self-lubricating: PEEK products in all plastic has outstanding sliding properties suitable for the stringent requirements of low coefficient of friction and abrasion use. The proportion of each carbon fiber, graphite, PTFE mixed modified PEEK better self-lubricating properties.
4 resistance to chemicals (resistance to corrosion): the PEEK product has excellent chemical resistance, it only concentrated sulfuric acid, can be dissolved or destroyed in the usual chemicals, its corrosion resistance of steel and nickel are similar.
5.Flame resistance: PEEK is very stable polymer 1.45mm thick samples, without any flame retardants can achieve the highest flame retardant standards.
6. Peeling resistance: the PEEK good peeling resistance and therefore can be made of coated thin wires or magnet wire, and can be used under harsh conditions.
