Recently, Reno has developed a new modified polyester polyol Raynol PS--400 series according to market demand. This product is an aromatic polyester polyol with high primary hydroxyl content, high benzene ring content, and functional The degree is 2.5, and the polyurethane rigid foam produced by this product has the following characteristics: Coffee Cup,Crack Resistant Coffee Cup,Durable Coffee Cups,Creative Porcelain Coffee Cup shaoxing qinzi business company ltd , https://www.qinzisx.com
1. Compared with Raynol PS—3152, the functionality is high, dimensional stability and curing performance are improved;
2. High activity and saving catalyst;
3. It is easy to mix with compounds such as isocyanate, and the formed polyurethane foam pores are even and fine, and the thermal conductivity is low;
4. Enhance the toughness of the foam, improve the adhesion of polyurethane to metal, plastic and other materials, effectively solve the problem of poor foam adhesion, foam crispness and shrinkage cracking in winter or low ambient temperature. Polyurethane rigid foam production enterprises and construction companies have many years of problems.
5, excellent flame retardant performance;
Mainly used in the production of polyurethane rigid foam, such as building sandwich foam, refrigerator, freezer foam and so on.
Especially suitable for high flame retardant polyurethane rigid foam, as a substitute for hard foam polyether, can replace 20-100% hard foam polyether
