What is the material of pop?

POP is a kind of polyether polyol grafted with vinyl polymer, commonly known as "polyether polyol" or "white polyether polymer polyol" for short. POP is a polymer-polyether dispersion, which belongs to organic filled polyether polyol and is used to prepare soft and semi-rigid polyurethane foam products with high load or high modulus.

Its appearance is generally white or light milky yellow, and it is made of polyether based on general polyether polyol (general flexible polyether triol and high-activity polyether), vinyl monomers such as acrylonitrile, styrene, methyl methacrylate, vinyl acetate, vinyl chloride and initiator by free radical grafting under the protection of nitrogen at 100 degree.

Polymer polyol is a kind of polyol containing organic filler, which can replace inorganic filler. It can not only make polyurethane foam have high bearing capacity and good resilience, but also improve the cell structure and physical and mechanical properties of the foam. It is an important polyol use for molding and block soft and semi-rigid polyurethane foam.

Extended data:

Polymer polyols are mainly used to produce high-load (HL) and high-resilience (HR) soft block foams and molded foams, which are used in carpet substrates, furniture cushions, vehicle seat cushions and automobile interior parts.

The 50% compression load of polyurethane foam produced by polymer polyol is more than double that of ordinary polyurethane soft foam with the same density, which means that the density of foam material with the same compression load can be greatly reduced by using polymer polyol, thus reducing the cost and having practical value.

Domestic polymer polyols can be divided into ordinary polymer polyols and high-activity polymer polyols, and the output of the two categories of products is increasing year by year. 20 1 1 year, the output of ordinary polymer polyol is 222,000 tons, and the output of high-activity polymer polyol is 70,000 tons. In 20 16 years, the output of ordinary polymer polyol increased to 308,000 tons, and the output of high-activity polymer polyol increased to 6,543.8+0.57 million tons.
