Perodox C

In the temperature range of 100-170°C, TBPB can be used as an initiator for the solution polymerization or copolymerization of acrylate and methacrylate,especially for the production of coatings. TBPB can also be used as initiator for bulk and suspensionpolymerization or copolymerization of acrylate and methacrylate.

TBPB can be used for the market segments: polymer production, polymer crosslinking,thermoset composites and acrylics production with their different applications/functions. For more information please check our website and/or contact us.

The reactivity of an organic peroxide is usually given by its half-life (t½) at various temperatures. TBPB in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:

0.1 hr at 142°C (288°F)

1 hr at 122°C (252°F)

10 hr at 103°C (217°F)

Formula1 kd = A·e-Ea/RT

Formula2 t½ = (ln2)/kd

Ea 151.59 kJ/mole

A 2.23E+16 s-1

T (273.15+°C) K

Organic peroxides are thermallyunstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

SADT 60°C (140°F)

Method The Heat Accumulation Storage Test is arecognized test method for the determinationof the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual ofTests and Criteria - United Nations, NewYork and Geneva).

Due to the relatively unstablenature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Do Sender Chem recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.
