Controlled rheology polypropylene (CR-PP): High melt- flow index polypropylene grades are produced by post reactor treatment. These high melt-flows are achieved by peroxide-initiated degradation during extrusion of the polypropylene. The advantage of this process is the high flexibility; the peroxide concentration controls the final viscosity. Coagent for flame retardant polystyrene: Polystyrene is made flame retardant by the use of halogen-containing additives such as hexabromocyclododecane (HBCD). BIBP-14SFL can be used as a synergist in such systems thereby leading to a significant reduction in the amount of HBCD required.

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 (Ts max. ) for each organic peroxide product.

Ts max.	20°C (68°F) to prevent caking
Note	BIPB-14SFL can be safely stored at 30°C (86°F) max without loss of activity.When stored under strictly recommended storage conditions, BIPB-14SFL will remain within the Nouryon specifications for a period of at least 12 months after delivery.

Packaging and transport

The standard packaging is a cardboard box for 4 x 5 kg peroxide. Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your Thousands Chemicals representative. BIPB- 14SFL is classified as Organic peroxide type D; solid, Division 5. 2; UN 3106.

Safety and handling

Keep containers tightly closed. Store and handle BIPB-14SFL 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 Safety Data Sheet (SDS) for further information on the safe storage, use and handling of BIPB-14SFL. This information should be thoroughly reviewed prior to acceptance of this product.
