Product Usage: LY-628 is a reactive flame retardant intermediate mainly used for flame retardant hard foam. It has a slightly faded viscous liquid appearance. It is mainly used as a reactive flame retardant for the production of Class I and Class II. Rigid polyurethane foam (PUR). The smoke volume and flame spread rate of foam materials containing LY-628 are very low. Foam materials processed with it can obtain excellent physical properties and have relatively low costs. They can also be used to produce flame-retardant polyurethane gaskets with elastic properties. body materials, coating adhesives and textiles.
