Applications
DEEP is a new efficient organophosphorus flame retardant. It can be added to various rigid polyurethane foams and foaming systems. Its flame retardant efficiency is 1.5~2 times TCPP.
DEEP is low in viscosity and does not contain halogen. Its chemical stability is good in the polyether polyol-isocyanate bicomponent system. Besides, DEEP is an efficient viscosity reducer. It improves the operability of aqueous foaming hard bubble and rigid polyurethane foam systems.
The DEEP dosage can be 20~25 shares for rigid foam complying with standard flame-retardant B2. However, DEEP is unsuitable for the system built with isocyanates, including a prepolymer and one-component polyfoam.
Storage
One year in shadow.
Packing
200kgs/iron drum.
