Silicone stabilizer is an essential part and play an important role in polyurethane rigid foam. PU rigid foam is formed by the interaction of Isocyanate and polyether polyols with various additives such as silicone oils, catalysts and blowing agents, etc. Polyurethane rigid foam is a thermal insulation material with excellent thermal insulation performance, most of cell structure is closed-cell type, which is inseparable from the role of silicone surfactant/stabilizer/additive.

Silicone stabilizer:(also named as silicone/silicone surfactant/additive). It improves the compatibility of component - emulsifying foam materials, stabilizing foam and control cell size. PU rigid foam can be used in widely application fields, such as: home appliance insulation, pipe insulation panel, spray foam, spraying and pipe, solar energy, wood imitation, OCF, etc. As the increasingly requirements of environmental regulations and energy standards of household appliances, the requirements for polyurethane rigid foam in refrigerators are gradually increasing, better thermal conductivity and lower energy  consumption level will be more popular in the market. High-end home appliances refrigerator need extremely high quality silicone, which need strong nucleation ability, low K factor, and few surface bubble. TOP WIN developed a product#XH-1625 can meet the requirements, it’s suitable for high-end refrigerator/freezers with C5, HFC, HFO or co-blown system, also provide low K factor.

Key features: low K factor, good nucleation ability, good emulsification ability, excellent foam ability and dimensional stability,  reduction of surface defects.

TOP WIN also produce many different kinds of silicone products suitable for different industry:Silicone surfactants for PU foam, silicone for PU  shoe sole/ footware, silicone release coating for paper and film, silicone additives for textile and leather, silicone additives for coating, silicone polyether for agriculture.
