Alumina Ceramics:

99 alumina ceramics have a wide range of applications in the field of daily consumer goods, such as building materials, pipes, plates or sheets, which are now partly replaced by cheaper PVC resins. ABS resin is used in construction-related fields, where extruded sheets are used for sanitary appliances such as bath boxes, swimming pool linings, etc., and injection-molded pipes and fittings are produced in small quantities for extrusion-molded telephone cables. The five largest ABS manufacturers in the world are as follows: Chi Mei Corporation of Taiwan, China, with a total production capacity of 1.25 million tons/year, of which the Tainan installation is 1 million tons/year, and the Zhenjiang installation is 250,000 tons/year; Bayer's total production capacity is 930,000 tons/year; LG Chem's total production capacity is 700,000 tons/year; General Electric GE Plastics' total production capacity is 650,000 tons/year; BASF's total production capacity is 560,000 tons/year, and the five largest companies account for 55.6% of the world's total production capacity. The five major manufacturers have accounted for more Mullite Ceramic Plate than half of the global ABS production capacity. Due to the large gap in the supply of ABS in mainland China, several major companies have exported a considerable part of their products to China. At the same time, Chi Mei and LG have successively set up factories in mainland China and have the intention of continuing to expand their capacity. Polyethylene (PE for short) is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum use temperature can reach -100~-70°C), has good chemical stability, and can withstand most acids and alkalis (not resistant to oxidation) Nature of acid). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was initially compiled for reference. Polyethylene was included in the list of three types of carcinogens.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
