Introduction Of PEEK Qualification Index

It is reported that the R & D and industrialization of the synthesis technology of copolyether ether ketone is a key project of the national "863" plan. In order to realize the industrialization of copolyether ether ketone as soon as possible, Liaoning Panjin Zhongrun Chemical Co., Ltd. cooperated with two domestic companies with this patent technology to establish Panjin Zhongrun special plastic Co., Ltd. At present, the company has a number of high-end special engineering plastics patents, such as copolyether ether ketone. Entrusted by the company, Tianke Co., Ltd. has carried out engineering Scale-up Development and design for the first phase 1000t / a copolyether ether ketone project. During the implementation of the project, the scientific research personnel of Tianke successfully broke through the key engineering and technical problems such as polymer synthesis, solvent extraction and separation, successfully transformed the patented technology of the laboratory into an industrial production device, and built the first standardized and industrial scale-up device for the production of copolyether ketone in China.

The completion and operation of the device not only breaks the long-term blockade and monopoly of western countries on the product, meets the needs of China's national defense and military industry, but also promotes the upgrading of products in aviation industry, electronic information, petrochemical industry, automobile manufacturing, medical and health care, household appliances and other related industries. At the same time, the industrialization achievements will create more and better social and economic benefits.

Copolyether ether ketone resin is a new type of engineering plastics, which belongs to linear aromatic polymer compound and has the best comprehensive performance in special engineering plastics. Its main physical properties are similar to those of PEEK resin, which can be used in the traditional field of PEEK resin. Copolyether ether ketone resin has the characteristics of high heat resistance, radiation resistance, corrosion resistance, fatigue resistance, high strength and good wear resistance. It is mainly used in the manufacture of wires, cable insulation materials, piston rings, detection sensors and other precision instruments, as well as aircraft structural materials and aircraft parts. It is also widely used in medical, coating and other industries. PEEK / PEEK must have the following points to become a qualified product:

1. Low creep.

2. High elastic modulus.

3. Excellent friction performance.

4. Wear resistant.

5. Resist the erosion of various media, comply with FDA certification, non-toxic.

6. Excellent chemical resistance.

7. Flame retardant.

Peek, together with polyphenylene sulfide (PPS), polysulfone (PSF), polyimide (PI), poly (aryl ester) (PAR) and liquid crystal polymer (LCP), has become five major special engineering plastics.
