Huacheng High Technology Company specialized in the production of polyester polyol, which is one of the most important domestic polyester polyol production factories.
Polyester polyol 3152
1, product introduction
Polyester polyol is one of a major raw material in polyester polyurethane. Polyester polyol of diverse specification and brands can produce polyurethane products by reaction with polyisocyanate which widely apply in producing rigid polyurethane foams, elastomers, adhesives, coatings, etc... It is widely used in external wall insulation, waterproof, plastic runway, flooring, packaging, tire, textile and other fields.
The XW-400 is mainly used for producing portfolio polyether foam of external wall thermal insulation coating and pipe material; it can significantly reduce the cost of polyether and obtain an excellent performance.
