Storage:

  • Due to relatively unstable nature of organic peroxides a loss of quantity can be detected over a period of time. To minimize loss of quantity, we recommend storage temperature for TBPB between 20 - 25°C.

Thermal Stability:

  • Organic peroxides are thermally unstable 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 of TBPB is 60°C.

Major Decomposition Products:

  • Acetone, Tert-butanol, Benzoic acid, Carbon dioxide, Benzene

Packaging And Transport:

  • The standard packaging is a 30 Kg HDPE container. TBPB is classified as Organic peroxide type C, liquid, Division 5.2 UN 3103.

Safety And Handling:

  • Rotate stock using the oldest material first. Avoid contact with skin, eyes and clothing. Use Personal Protective Equipment. Keep containers closed to prevent contamination. Keep away from sources of heat, sparks or flame. Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g. accelerators, driers, metal soaps). Do not add to hot solvents or monomers as a violent decomposition and/or reaction may result. Keep in original container. DO NOT USE NEAR FOOD OR DRINK. Wash thoroughly after handling.
