China polyurethane prepolymer for footwear - find detail polyurethane footwear, pu footwear from xuchuan chemical (suzhou) co., ltd. When the styrene content in the fine polymer particles contained in the polymer-polyol B is at least 40% by weight, the white polyurethane foam attains to a usable level. POLYURETHANE PREPOLYMER (FOR SHOE SOLE) (INDUSTRIAL RAW MATERIAL FOR BULK CONSUMPTION) CONTACT US: Nina Mob:+86-18767692555 Email:ynn20203@gmail.com ：yenina@hengtaiyuan.com Whatsapp:+86-18767692555 According to the present invention, there can be provided a polyurethane foam for shoe soles having acceptable appearance without having peeling of skin layers or molding shrinkage in the average density of 0.15 to 0.5 g/cm3. 5 I 2â manufactured by Kao Corporation; N,N,Nâ²,Nâ²,Nâ³-pentamethyldiethylenetriamine typically exemplified by trade name: âKAOLIZER No. 0.5 0.5 It is desired that the content of the oxyethylene group in the polyoxypropylene polyols is at most 35% by weight from the viewpoint of water resistance, and that the content is at least 5% by weight from the viewpoint of the ratio of the terminal primary hydroxyl group to the total terminal hydroxyl groups. When the process B is employed, as a method for polymerizing a polymerizable unsaturated group-containing monomer in a polyether-polyol having two or more hydroxyl groups, there can be used a known method, such as a method comprising polymerizing a polymerizable unsaturated group-containing monomer in a polyether-polyol having two or more hydroxyl groups in the presence of a dispersion stabilizer and a radical polymerization initiator. The present invention relates to a polyurethane foam for shoe soles, which can be desirably used, for instance, for shoe soles for sport shoes, particularly for low-density soles. 2) Polymer-Polyol II: Polymer-polyol [color: white] composed of fine particles prepared by polymerizing acrylonitrile monomer and styrene monomer in a ratio of acrylonitrile monomer/styrene monomer of 50% by weight/50% by weight in polyoxypropylene triol having a polyoxyethylene terminal and a molecular weight of 3,000 (content of oxyethylene group: 20% by weight; ratio of terminal primary hydroxyl group to total terminal hydroxyl groups: 71%), which was prepared by sequentially adding propylene oxide and ethylene oxide to glycerol. Taobao Global 11. Also, from the viewpoint of viscosity during handling, it is desired that the upper limit of the molecular weight is at most 20,000, preferably at most 10,000. 70 0.5 â8 x 3 1.3 â 11.4 Slightly LIgh yellow liquid ,but normally for long time in low termperature could be solid. The polyether-polyol A includes polyoxypropylene polyols prepared by adding ethylene oxide to the terminal hydroxyl group of a polyoxypropylene polyol, having a molecular weight of at least 1,500 per one hydroxyl group; and polyoxytetramethylene glycol prepared by ring-opening polymerization of tetrahydrofuran, having a molecular weight of at least 1,000, or mixtures thereof.
