Flame retardant polyester polyol PF series
- PF series products PF series products contain higher molecular structure of benzene ring introduced flame retardant elements, in the foam formation process, participate in chemical reactions, directly linked to the structure of the foam, become part of the foam, Therefore, it does not migrate in the foam preservation process, with permanent flame-retardant effect.
PF series products are reactive flame retardant polyester polyol, mainly used in rigid polyurethane foam and soft foam, which can greatly improve the flame retardancy of foam, and improve the high temperature resistance of foam. For example, B _ 1 / B _ 2 flame retardant grade / VO flame-retardant grade. It is suitable for polyurethane PUR/PIR continuous hard / soft surface plate, batch plate, cold storage spraying, refrigerated car heat preservation, cryogenic insulation, electronic enema and flame retardant sponge and so on.
1. It has good mutual solubility with each component in the composite polyether to ensure that the composite material is not stratified.
2. High aromatics content can significantly improve the flame retardancy and ensure a low smoke density.
3。 The physical property index was optimized and mixed with other components of the composite polyol, and the storage period of the composite material was long.
4。 Excellent structural rigidity to ensure the strength, hardness and dimensional stability of the product;
