Grade B1 High Flame Retardant Spraying Combined Polyether

This product is a kind of flame-retardant combined polyether with HCFC-141b as foaming agent. By reacting it with isocyanate of the same quality, polyurethane foam with excellent performance can be prepared. The flame-retardant property of foam reaches B1 level, which is suitable for spraying construction of external wall insulation.

This product's typical performance including: high closed pore rate and good waterproof performance, good thermal insulation effect, high compressive strength, excellent fire resistance.

Spraying Combined Polyether for Cold Storage

This product is a kind of combined polyether polyol, which contains polyether polyester polyol, foaming agent, foam homogenizer, catalyst, flame retardant, cross-linking agent, etc. When it reacts with isocyanate with the same quality, the generated foam has high closed cell rate and good thermal insulation performance, which is suitable for thermal insulation spraying construction in cold storage. Can be adjusted according to customer requirements.

This product's typical performance including: high closed pore rate and good waterproof performance, good thermal insulation effect, high yield, no shrinkage and no cracking.

All-Water-Based Soft Low-Density Spraying Combined Polyether

This product is a fluorine-free and environment-friendly combination polyether with only water as foaming agent. Polyurethane foam with excellent performance can be prepared by reacting it with isocyanate of the same quality. The flame-retardant property of foam reaches B1 grade which is suitable for external wall thermal insulation spraying construction in special occasions. This product fills the domestic technical gap and reaches the international leading level. It can be applied to the sound insulation and heat preservation of cinemas and conference halls, the filling of hollow gaps in external walls, the spraying of bus ceilings, the hollow spraying of curtain walls, etc., and is especially suitable for the building system with long backbone hanging.

This product's typical performance including: good thermal insulation and sound insulation effects, fluorine-free and environment-friendly, with large foaming multiple, excellent fire resistance.

Solar Type Combined Polyether

YTYN series combined polyether polyol is a polyurethane foam insulation layer specially designed for solar water tanks. Besides foaming agent, it contains raw materials and all additives needed for the production of rigid polyurethane foam.
