Product Usage:
1,PHT-4 Diol is a reactive flame retardant intermediate mainly used for flame retardant hard foam. It looks like a slightly faded viscous liquid. It is mainly used as a reactive flame retardant for the production of Class I and II. Grade polyurethane rigid foam (PUR).
2,The amount of smoke and flame spread of foam materials containing PHT-4 Diol are very low. The foam materials processed with it can obtain excellent physical properties and the cost is relatively low. It can also be used to produce flame-retardant polyurethane gaskets. Elastomeric materials, coating adhesives and textiles.
