Overview Of The Market Development Of China's Polishing Pad Industry in 2020

According to the "China Polishing Pad Market Research and Investment Forecast Report (2020 Edition)" released by Limu Information Consulting, polishing materials can be divided into polishing fluids, polishing pads, conditioners, cleaning agents, etc. according to different categories, of which the largest proportion It is a polishing liquid, about 49%. Another key consumable used in polishing is the polishing pad, which accounts for close to one-third of all polishing materials.

The types of polishing pads can be divided into three types: polymer polishing pads, non-woven polishing pads, and composite polishing pads according to the material structure.

It can be known from the practice of CMP polishing that soft polishing pads such as non-woven fabrics can achieve a small processing deterioration layer and surface roughness, but it is difficult to achieve high-efficiency planarization processing; excessively hard polishing pads such as polymer polishing pads can achieve high Polishing efficiency, but poor non-uniformity and easy to damage the surface of the material. In order to take into account the requirements of flatness and non-uniformity, the upper and lower two-layer composite structure can be adopted, and the composite polishing pad has emerged and has become the mainstream of market demand.

Compared with international manufacturers, domestic manufacturers, as specialized polishing pad companies, are more flexible in meeting the needs of local customers than the single division of the international giants, especially for products with highly customized attributes such as polishing pads. Therefore, the future sales of domestic polishing pads are also expected to continue to expand
