Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.
TBPB is a low volatility ,high purity,liquid, aromatic peroxuester.it is effective as medium of a broad spectrum of monomers e.g .styrene.ethylenn,acrylics.it is also used to cure (copolymerzation) unsaturated resins .
TBPB is a clear light yellow liquid, which is little soluble in water but well in many organic solvents such as ethanol or phthalate.
As peroxo compound, TBPB contains about 8.16 wt% of active oxygen and has a self accelerating decomposition temperature (SADT) of about 60 °C. The SADT is the lowest temperature at which self-accelerating decomposition in the transport packaging can occur within a week, and which should not be exceeded while storage or transportation.[2] TBPB should therefore be stored between minimum 10 °C (below solidification) and maximum 50 °C. Dilution with a high-boiling solvent increases the SADT. The half-life of TBPB, in which 50% of the peroxy ester is decomposed, is 10 hours at 104 °C, one hour at 124 °C and one minute at 165 °C. Amines, metal ions, strong acids and bases, as well as strong reducing and oxidizing agents accelerate the decomposition of TBPB even in low concentrations.[ However, TBPB is one of the safest peresters or organic peroxides in handling. The main decomposition products of tert-butyl peroxybenzoate are carbon dioxide, acetone, methane, tert-butanol, benzoic acid and benzene.

Oak Forest Fire Department news (more)
Hey everyone,
I just came across this update from the Oak Forest firefighters union local 3039 Facebook page, and it's got both some concerning news and a bit of hope on the horizon.
First off, the bad news: right now, there aren’t any operational fire trucks ("apparatus") available for service in Oak Forest. This is definitely not ideal, especially when it comes to ensuring emergency services are always ready to go.
But here’s where things get interesting—our neighboring communities are stepping up to help out. To the west, both the Village of Tinley Park Public Safety and the Orland Fire Protection District in Illinois have generously offered to lend one of their engines to keep emergency services running smoothly in Oak Forest. It’s great to see such solidarity between these departments!
On the brighter side, there’s some fantastic news too. We’ve been informed that funds have already been allocated, and approval has been given to buy brand-new fire apparatus! The team is super excited about this development and is eager to move forward with the procurement process as swiftly as possible. It’s reassuring to know that the situation is being addressed, and soon enough, Oak Forest will have its own fully functional fleet again.
In the meantime, I wanted to share a couple of photos from the Oak Forest FD. These images really highlight the dedication and professionalism of our local firefighters, who continue to serve despite these challenges.
Thanks to Martin for sharing this information! Let’s hope for a speedy resolution and continued support for our firefighters.
Take care,
[Your Name]
