Product details

TBPB | CAS 614-45-9 | Tert-butyl peroxybenzoate

Tert-butyl peroxybenzoate is an organic peroxide.Its CAS number is 614-45-9.It is a colorless to slightly yellow liquid and has a slight aromatic odor.It is insoluble in water and soluble in organic solvents.

Tert-butyl peroxybenzoate is also known as TBPB.It is widely used as an initiator in polymerization processes such as ethylene, styrene, propylene, vinyl acetate, diallyl phthalate, and isobutylene. In the curing process of unsaturated polyester, it is widely used in molding processes such as SMC, BMC, DMC pulling agents, and can also be used in two-component curing systems with higher activity such as MEPK, BPO, or TBPO.

TBPB-99,TBPB-75A,TBPB-65B are all available.You can contanct us for more informations.
