Applications
Polymerization of styrene
TBPB can be used for the polymerization and copolymerization of styrene in the temperature range of 100-140℃. During polymerization the temperature is increased in steps.
Polymerization of acrylates & methacrylates
TBPB can be used as initiator for the solution (co)polymerization of acrylates and methcrylates in the temperatures range of 100-170℃, amongst others for the coatings. TBPB can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methcrylates.
Polymerization of ethylene
TBPB is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice. Depending on reaction conditions, TBPB is active in the temperature range of 220-270℃.
Other Polymerization Applications
TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
Crosslinking Peroxides
TBPB is suitable for crosslinking of EPDM rubber compounds at ambient temperature within some weeks. Rubber compounds containing TBPB have moderate processing safety in combination with a very high speed of cure.
Peroxides for Thermoset Resins
Tert-butyl peroxybenzoate is an aromatic perester which is used for the curing of unsaturated polyester resins at elevated temperatures. TBPB is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
Frequently Asked Questions (FAQ)
What is the chemical name and CAS number of TBPB?
TBPB stands for Tert-Butyl peroxybenzoate. Its CAS number is 614-45-9, and its molecular formula is C11H14O3.
What are the main specifications of TBPB?
Our TBPB is a clear liquid with an assay of 98.5% min. It has a maximum color specification of 50 Pt-Co, maximum tert-Butyl hydroperoxide content of 1000 mg/kg, and maximum inorganic + organic hydrolyzable chloride of 50 mg/kg.
What packaging options are available for TBPB?
The standard packaging sizes for TBPB are 25 kg net or 180 kg net. Smaller or customized packaging sizes can also be provided upon request.
In what polymerization processes is TBPB used as an initiator?
TBPB is used as an initiator for polymerizing styrene (100-140℃), acrylates and methacrylates (100-170℃), ethylene under high pressure (220-270℃), as well as acrylonitrile and vinyl acetate.
How does TBPB perform in rubber crosslinking and thermoset resins?
For rubber, TBPB is ideal for crosslinking EPDM compounds at ambient temperature, offering moderate safety and high cure speeds. For thermoset resins, it is preferred for curing unsaturated polyester (UP) resins in Hot Press Moulding formulations (SMC, BMC, ZMC) within 120-170℃.
