Package and Storage
Applications
TBPB may be utilized for the polymerization and copolymerization of styrene within the 100-140℃ temperature range. The temperature is gradually raised during the polymerization process.
TBPB can serve as an initiator for the solution (co)polymerization of acrylates and methacrylates at temperatures ranging from 100 to 170℃, particularly for coatings. It can also be used as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates.
TBPB is an effective initiator for the polymerization of ethylene under high pressure in both autoclave and tubular processes. Combinations with other peroxides are employed to achieve a wide range of polymerization temperatures. TBPB exhibits activity within the 220-270℃ temperature range, depending on the reaction conditions.
TBPB can also be employed for the (co)polymerization of acrylonitrile and vinyl acetate.
TBPB is suitable for crosslinking EPDM rubber compounds at ambient temperature over several weeks. Rubber compounds containing TBPB offer a balance between processing safety and rapid curing.
Tert-butyl peroxybenzoate, an aromatic perester, is utilized for curing unsaturated polyester resins at elevated temperatures. TBPB is the preferred curing agent for UP resin-based Hot Press Moulding formulations (SMC, BMC, ZMC, etc.) within the 120-170℃ temperature range.
