BPDY-145-45B-PD is a 45% formulation on an inert carrier system in powder form.

Specifications

Appearance	Off-white powder
Assay	44.0-46.0 %

Applications

BPDY-145-45B-PD is a bifunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Safe processing temperature: 145°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 185°C (rheometer t90 about 12 min.).

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	70°C (158°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.

Ts Max.	30°C (86°F)
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

In North America BPDY-145-45B-PD is packed in non-returnable, poly-lined cartons of 40 lb net weight. In other regions the standard packaging is a cardboard box for 15 kg peroxide formulation. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Thousands Chemicals representative. BPDY-145-45B-PD is classified as Organic peroxide type D; solid, Division 5. 2; UN 3106.

Safety and handling

Keep containers tightly closed. Store and handle BPDY-145-45B-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, alkalines and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of BPDY-145-45B-PD. This information should be thoroughly reviewed prior to acceptance of this product.
