PRODUCT DETAILS

BQ8024/8025/8026/8027 are the polyether polyol used for sandwich panels,it’s the rigid foams used for building insulation

 

CAS:9003-11-6

Color :Colorless to brownish-red transparent liquid

 

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 .

 

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.

 

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.

 

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:

 

- 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.

 

- 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.

 

- 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.

 

- Durability: with a good durability, which can maintain the thermal insulation properties of polyurethane foam and extend its service life.

 

Normal packing of the polyether polyol foam

-Iron drum for packing, net weight 200kg;

-Tons of barrels packaging, net weight 1000kg.

-Other special request also can be accepted

 

We also have other series polyether polyol used for sandwich panels to satisfied your other requests,just feel free to contact us.
