PEEK， The Chinese name is polyetheretherketone, which is a semi crystalline special engineering plastic. It is known as the “pyramid tip” material in the engineering plastics industry, due to its extremely excellent comprehensive performance, and can replace traditional materials such as metals and ceramics in many harsh environments.
PEEK belongs to the polyaryletherketone (PAEK) family, and its molecular structure contains rigid benzene rings and polar ketone bonds, which endow it with extremely high stability, mechanical strength, and heat resistance.
It was developed and commercially produced by the British company Victrex in the late 1970s and is still one of its main manufacturers.
The PAEK family of polyaryletherketone includes:
PEEK, PEKK, PEK, PEEKK, PEKEKK, etc.
Key Features
- Excellent high temperature resistance
Long term use temperature: Can be used continuously for a long time in high temperature environments.
Short term heat resistance: Some materials can even exceed 300 ℃ in instantaneous use temperature.
High temperature performance retention rate: It can still maintain extremely high mechanical strength and rigidity at high temperatures, with minimal performance degradation.
- Extremely high mechanical strength
High strength and rigidity: Its strength and rigidity are close to certain metal alloys.
Excellent fatigue resistance: It can maintain its performance under repeated stress cycles and is not easily broken.
Excellent creep resistance: Under long-term continuous stress, the deformation is minimal and the size is stable.
- Excellent wear and friction resistance
Self lubrication: With a low coefficient of friction, it already has good sliding characteristics.
High wear resistance: Especially when blended and modified with materials such as carbon fiber, graphite, PTFE, etc., its wear resistance can surpass many metal materials and become an ideal wear-resistant material.
The biggest advantage of PEEK lies in its comprehensive and extreme performance combination.
It is not outstanding in one or two aspects, but has reached the top level of engineering plastics in multiple dimensions such as high temperature resistance, mechanical strength, chemical resistance, wear resistance, and electrical performance.
This enables it to replace traditional materials such as metals and ceramics in many extremely harsh environments, such as high temperature, high pressure, high wear, and strong corrosion, thereby achieving weight reduction, noise reduction, lubrication free, and extended lifespan effects.
Although its raw materials and processing costs are high, PEEK is often an indispensable key material for cutting-edge fields that require extremely high reliability, safety, and performance.
PEEK belongs to synthetic resin, and its upstream industries are chemical raw materials and chemical fiber manufacturing.
The main raw materials include fluoroketone (the most critical), hydroquinone, diphenyl sulfone, and sodium carbonate, while additives include carbon fiber, glass fiber, and PTFE; The midstream includes the manufacturing of PEEK products such as PEEK particles, PEEK powders, PEEK reinforced particles, etc; Downstream refers to various terminal fields.
SUQING PEEK SQ210 material has outstanding characteristics such as high temperature resistance, excellent mechanical strength, chemical corrosion resistance, self-lubricating and wear-resistant, flame retardant, low smoke and non-toxic, and stable electrical performance.
Most of the PEEK SQ210 materials used in the plastic engine meet the stringent requirements for lightweight, durability, and reliability in high-end manufacturing fields such as aerospace, automotive manufacturing, electronics and electrical, energy industry, and medical equipment.
Choosing plastic grade PEEK not only means obtaining a material with performance comparable to international first-class standards, but also enjoying the reliable supply chain, more competitive cost advantages, and efficient localized technical services brought by domestic brands. It is an ideal solution to replace metals and cope with extreme working conditions.
