UPR production and consumption in China is the highest in the world, the production capacity of 2 million tons/year, output of more than 1 million tons/year, America's 2004 annual output of 870000 tons. Developed during the period of "15" gas dry gel, high toughness gel, uv curing resins and gel coat. Gel coating the annual output of more than 12000 tons. Between benzene resin, vinyl ester resin production is 10 times "respectively in the period of growth and 5 times.

Unsaturated polyester resin curing agent used in the production of varieties and growth speed. Only MEKP (methyl ethyl ketone peroxide) annual output reached 20000 tons. Traditional cyclohexanone peroxide (HCH) production volume of less than one thousand tons, liquid HCH has a small market, high requirement for piano paint, etc. Benzoyl peroxide (BPO), TBPB (benzoic acid tert-butyl ester peroxide), TBPO [peroxide (2 - ethyl caproic acid tert-butyl ester], TBHP (tert-butyl) with hydrogen peroxide and other traditional and newly developed initiator, improves the production efficiency, and improves the appearance quality of the product.

Promoter annual sales of 15000 tons. Commonly used cobalt naphthenate (commonly known as "cobalt naphthenate"), different octylic acid cobalt, colorless accelerator (containing cobalt naphthenate, containing potassium naphthenate and naphthenic acid containing copper, etc.), etc. 3. For naphthenic acid is oil fractionation of fatty acids, due to different properties and fractions of crude oil, the molecular weight, there are many differences in the production of cobalt salt content is difficult to ensure accurate, so the consumption is on the decline this year, less than 10% of the sales of the promoter. Cobalt quantitative performance stability, production has more than 60%. Adopting colorless accelerator, man-made stone products such as production volume accounted for about 20% of the total sales promoter.
