Packaging and transport

The standard packaging is a HDPE can for 20 kg peroxide formulation. Both packaging and transport meet the international regulations.
DTBP is classified as Organic peroxide type E; liquid, Division 5.2; UN 3107; PG II.

Safety and handling

Keep away from open fire, sparks and other sources of heat or ignition. 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 DTBP. This information should be thoroughly reviewed prior to acceptance of this product.

Application

1. Rubber crosslinking

Due to its high volatility, DTBP is mainly used for compounds that are cross-linked immediately after mixing.

2. Polymerization of ethylene

DTBP is an efficient initirtor for the ethylene polymerization under high pressure in both autoclave and tubular processes.
Depending on reaction conffitions. DTBP is active in the temperation rang of 240-280°C, due to the high volatility of DTBP, it requires severe precaution in handing and metering.
