。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 Safety Data Sheet (SDS) for further information
on the safe storage, use and handling of LQ-DTBP. This information should be thoroughly
reviewed prior to acceptance of this product.
。Application
1. Rubber crosslinking
Due to its high volatility, LQ-DTBP is mainly used for compounds that are crosslinked
immediately after mixing.
2. Polymerization of ethylene
LQ-DTBP is an efficient initirtor for the ethylene polymerization under high pressure in both
autoclave and tubular processes.
Depending on reaction conffitions. LQ-DTBP is active in the temperation rang of 240-280°
C ,Due to the high volatility of LQ-DTBP it requires severe precaution in handing and
metering.
