(Summary description)my country's UPR production and consumption have ranked first in the world, with a production capacity of 2 million tons/year and an output of more than 1 million tons/year. In 2004, the U.S. produced 870,000 tons. During the "Tenth Five-Year Plan" period, air-drying gel coat, high-toughness mold gel coat, UV-curable resin and gel coat were successfully developed. The annual output of gel coat resin exceeds 12,000 tons. The production and sales volume of m-phenylene resin and vinyl ester resin increased by 10 times and 5 times respectively compared with the "Ninth Five-Year Plan" period.

my country's UPR production and consumption have ranked first in the world, with a production capacity of 2 million tons/year and an output of more than 1 million tons/year. In 2004, the U.S. produced 870,000 tons. During the "Tenth Five-Year Plan" period, air-drying gel coat, high-toughness mold gel coat, UV-curable resin and gel coat were successfully developed. The annual output of gel coat resin exceeds 12,000 tons. The production and sales volume of m-phenylene resin and vinyl ester resin increased by 10 times and 5 times respectively compared with the "Ninth Five-Year Plan" period.
The variety and output of curing agents used in unsaturated polyester resins have grown rapidly. The annual output of MEKP (methyl ethyl ketone peroxide) alone has reached 20,000 tons. The production and sales volume of traditional cyclohexanone peroxide (HCH) is less than 1,000 tons, and there is still a small market for liquid HCH, which is used in piano coatings and other places with high requirements. BPO (benzoyl peroxide), TBPB (tert-butyl peroxybenzoate), TBPO [tert-butyl peroxy(2-ethyl)hexanoate], TBHP (tert-butyl hydroperoxide) and other traditional And newly developed initiators, improve production efficiency and improve product appearance quality.
The annual production and sales volume of accelerators reaches 15,000 tons. Commonly used cobalt naphthenate (commonly known as "cobalt naphthenate"), cobalt isooctanoate, colorless accelerators (cobalt naphthenate, potassium naphthenate, copper naphthenate, etc.) Because naphthenic acid is a fatty acid obtained by fractional distillation of petroleum, the molecular weight of the crude oil is different due to the different properties and fractions of the crude oil. It is difficult to accurately guarantee the content of cobalt salts produced by it. Therefore, the dosage is on a downward trend this year, which is less than 10% of the sales volume of accelerators. The performance of cobalt isooctanoate is stable, and the production and sales volume has exceeded 60%. The production of artificial stone and other products uses colorless accelerators, and the market volume accounts for about 20% of all accelerator sales.
