Half life data

The most importantacteristic of a crosslinking peroxide is its decomposition rate expressed

by its half life (t?) at various temperatures. FDTBP in a EPDM compound:

t? = 0.1 hr 1 hr 10 hr at 176°C 154°C 120°C

Storage

Due to the relatively unstable nature ofganic peroxides, a loss of quality will occur over a period of time. To minimize the loss of quality, we recommend a maximum storage temperature (Ts max.) eachganic peroxide. A minimum storage temperature (Ts min.) is given if an

undesirable physical process (e.g. solidification phase separation) is known to occur below the

temperature indicated.

Ts max. = 40°C  Ts min. = -30°C

When stored according to these recommended storage conditions, DTBP will remain within the specifications fa period of at least six months after delivery.

Thermalstabilityganic peroxides are thermally unstable substances which may undergo self-accelerating decomposition. The lowest temperature at which selfaccelerating decomposition may occur with a substance in the packaging as used ftransport is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat

Accumulation Storage Test.

FDTBP SADT : 80°C

Emergency temperature (Tem) : 75°C

No control temperature (Tc) required

Hazardous reactions

Oxidizing agent. Decomposes violently under the influence of heat by contact with reducing agents.

Never mix with accelerators.

Safety handling

Keep away from open fire, sparks other sources of heat ignition. Avoid contact with reducing agents (e.g. amines), acids, alkalis heavy metal compounds (e.g. accelerators, driers metal soaps). Please refer to the Safety Data Sheet (SDS) ffurther information on the safe storage, use handling of DTBP. This information should be thoroughly reviewed prito

acceptance of this product.
