Applications

DHBP-101-45B-PD is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins. Rubber compounds containing DHBP-101-45B-PD have excellent scorch safety.

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 is determined on the basis of the Heat Accumulation Storage Test.

SADT	80°C (176°F)
Method	The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria – United Nations, New York and Geneva).

Storage

Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Thousands Chemicals recommends a maximum storage temperature.

Note	When stored under these recommended storage conditions, Trigonox® 101-45B- PD will remain within the Nouryon specifications for a period of at least six months after delivery.

Packaging and transport

DHBP-101-45B-PD is packed in non-returnable poly-lined cartons of 50 lb net weight. Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your Thousands Chemicals representative. DHBP-101-45B-PD is classified as Organic peroxide type E; solid, Division 5. 2; UN 3108.

Safety and handling

Keep containers tightly closed. Store and handle DHBP-101-45B-PD in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of DHBP-101-45B-PD. This information should be thoroughly reviewed prior to acceptance of this product.
