What material is PEEK?

PEEK (polyether ether ketone) resin is a special engineering plastic with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing. It is recognized as the thermoplastic material with the highest comprehensive performance for harsh environments. The following POM plastic manufacturer small series for you to introduce:

What material is PEEK? This question has popped up frequently on major search engines in recent years. There are two reasons: First, PEEK has been widely used in recent years, making people want to know more about this material. With the continuous improvement of product performance, as well as the price of PEEK materials continues to decline, PEEK has been from the initial in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts, to now in the machinery, electronics, chemical, automotive and other high-tech industrial fields are widely used, according to the industry and the required specifications, to manufacture parts with excellent performance. Second, because of the breakthrough in domestic research on special plastics, the current technical research and production capacity of domestic PEEK materials has been greatly improved, although there is still a certain gap compared with imported products, but the time for domestic PEEK products to replace imported products will not be long, we should more comprehensively understand what PEEK materials are.

The reason why the use of PEEK is more and more extensive is inseparable from product characteristics. The main properties of PEEK material are as follows:

1, temperature resistance, good thermal stability, ultra-high heat resistance, HDT above 315 degrees Celsius, UL continuous use temperature of 260 degrees Celsius.

2, mechanical properties PEEK is a plastic with both toughness and rigidity and a balance. In particular, its excellent fatigue resistance to alternating stress is the most outstanding among all plastics, comparable to alloy materials.

3, self-lubricating PEEK has outstanding sliding characteristics in all plastics, suitable for strict requirements of low friction coefficient and wear resistance. In particular, carbon fiber, graphite mixed modified PEEK with a certain proportion of better self-lubrication performance.

4, chemical resistance (corrosion resistance)PEEK has excellent chemical resistance. In the usual chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to nickel steel.

5, flame retardant PEEK is a very stable polymer, 1.45mm thick sample, without any flame retardant can achieve the highest flame retardant standards.

6, peel resistance PEEK peeling resistance is very good, so it can be made into a thin coating or electromagnetic wire, and can be used under harsh conditions.

7, radiation resistance high radiation resistance ability is very strong, more than the general resin in the best radiation resistance polystyrene. The high performance can be made to maintain good insulation ability when the gamma irradiation dose reaches 1100Mrad.

8, hydrolysis resistance PEEK and its composite materials are not affected by the chemical effects of water and high pressure water vapor, and products made of this material can still maintain excellent characteristics in continuous use of high temperature and high pressure water.

With the deepening of PEEK research, more and more performance can be found, while the application field is also expanding, in recent years, PEEK material is widely used in the medical field, with high-performance medical grade polymer material PEEK to replace the inherent metal, ceramic artificial joints, breaking the international monopoly situation in the high-end market of artificial joints.
