CAS No. 56706-10-6 is a polyether polyol with a molecular weight of 400-500, which is mainly used as a raw material for polyurethane foam. It is a colorless transparent liquid with a relative density of 0.92-0.98 g/ml. This polyether polyol can be used to produce polyurethane foam with excellent physical and mechanical properties, such as low water absorption, low thermal conductivity, excellent acoustic insulation, and good thermal insulation. In addition, it is also used as a raw material in the production of elastomers, coatings, adhesives, sealants, binders, and other products.


This polyether polyol has a relatively high reactivity, making it suitable for a variety of polyurethane foam production processes. It is also highly resistant to hydrolysis, oxidation and UV radiation. Furthermore, it has excellent compatibility with other polyols, allowing for a wide range of foam formulations. Additionally, it has a low viscosity, making it easier to handle and process.


CAS No. 56706-10-6 is an environmentally friendly product, as it does not contain any aromatic or halogenated compounds. It is also non-irritating and non-toxic, making it suitable for consumer applications. Furthermore, it is compliant with many international standards, such as REACH, RoHS, and Biocide Directive. This product is widely used in the automotive, construction, furniture, and footwear industries.
