Spray Blend Polyol EX-7030 Used In Waterproofing Thermal Insulation Projects
Description
EX-7030 is a spray-type blended polyol tailored for water-blown foam formulations.
It is extensively applied in external wall thermal insulation, integrated insulation & waterproofing works, cold storage insulation and other heat preservation projects. Boasting superior temperature tolerance and good blending performance, it fits diverse construction conditions and various operating equipment. The finished foam delivers excellent heat insulation effect, great crack resistance, high closed-cell rate, strong compression resistance and reliable bonding property.
