Polyurethane sieve is a kind of porous polyurethane raw materials to produce products mesh sieve for: crack, rectangular, circular, square polyurethane sieve polyurethane sieve main application industries: coal washing, coking plants, mines, power plants After dredging companies, metallurgy, petroleum, petrochemical and other enterprises with DMMP two kinds of flame retardant TCEP using different proportions of complex, better than a single flame retardant polyurethane sieve, when TCEP: DMMP = 1: 2 (Quality procurement ratio) polyurethane sieve, foam at the same time to meet the oxygen index Buying polyurethane sieve, other physical properties are better. Adjusting the isocyanate index of 3 mine polyurethane sieve manufacturers, additional trimerization catalyst, the resulting flame retardant polyurethane foam prepared oxygen index of 32, to GB 8624-1997 "supplies burning behavior in" under the BI grade (flame retardant grade). Polyurethane sieve manufacturers, Tsinghua plastic (certified), polyurethane sieve provided by the Engineering Plastics Co., Tsinghua ShangYinXian. ShangYinXian Tsinghua Engineering Plastics Co. (www.tyqhgc.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Tsinghua engineering leadership with the staff warmly welcome all inquiries negotiations to create a better future Tsinghua engineering.
