Application

DEEP is a new efficient organophosphorus flame retardant.It can be added to various rigid polyurethane foam all kinds of foaming system. Its flame retardant efficiency is 1.5-2 times of 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 system and rigid polyurethane foam system.

The DEEP dosage can be as 20-25 share for rigid foam complied with flame-retardant standard B2. DEEP is not suitable for the system built with isocyanates including a prepolymer and one-component polyfoam.

Storage

 

One year in shadow.
