(TBHP) is a kind of alkyl organic hydroperoxides with low volatility. It can be used both as the initiator for the

polymerization of emulsion, like polyvinyl chloride and polyacrylic acid, and the raw material for synthesizing

other organic peroxides.


Tert Butyl Hydroperoxide(TBHP) is volatile and flammable, so its storage should be

pressure-tight and avoiding fire. Store and carry as organic peroxide. Recommended storage temperature

5—30°C. Storage stability as from date of delivery 6 months.
