Product Details
BQ8024/8025/8026/8027 are the polyether polyol used for sandwich panels,it’s the rigid foams used for building insulation
Â
CAS:9003-11-6
Color :Colorless to brownish-red transparent liquid
Â
BQ8024 is the polyether based polyurethane foam for slabs, using self-produced high flame-retardant polyether polyols, which has good emulsifying properties and is suitable for continuous plate production under various process conditions. The finished foam has good compressive strength and flame-retardant grades up to standard .
Â
BQ8025 ,the PU polyurethane foam for sandwich panels, can be used for customer customized, and suitable for continuous plate production. Materials will not delaminate for long-term storage , which can meet the requirements of B2 flame retardant.
Â
BQ8026 is one blend polyol with good compatibility and no delamination for long-term storage. It is suitable for the fabrication of intermittent cold storage hook boards. The resulting foam shows good compressive strength and dimensional change at low temperatures.
Â
BQ8027 is specially designed for HFC-245fa/HFC -365mic, ODP value is 0, no damage to oxygen layer, customer special requirements can be customized.

Advantages of using polyether polyol in sandwich panels:
Â
- Excellent thermal insulation: Polyurethane foam made from polyether polyol has excellent thermal insulation properties, which can effectively reduce heat loss and improve the energy efficiency of buildings.
Â
- Strong bonding: The adhesive properties of polyurethane foam result in a strong bond between the outer layers and the core material, which can improve the structural integrity of sandwich panels.
Â
- Chemical resistance: Polyether polyol has good chemical resistance, which can resist the corrosion of acids, alkalis, and solvents, and maintain the stability of sandwich panels.
Â
- Durability: with a good durability, which can maintain the thermal insulation properties of polyurethane foam and extend its service life.
Â
Normal packing of the polyether polyol foam
