Primarily, TBPB is used as a radical initiator, either in the polymerization of e.g. ethylene (to LDPE), vinyl chloride, styrene or acrylic esters or as so-called unsaturated polyester resins (UP resins).[1] The quantity used for the curing of UP resins is about 1-2%   Properties TBPB is a clear light yellow liquid, which is little soluble in water but well in many organic solvents such as ethanol or phthalate.   Storage and Handling Store TBPB in a cool dry place below 30°C temperature. Avoid direct sunlight, rough handling.
