。Storage
For LQ-DBHP Ts max.= 30℃ and
Ts min. = -25℃
。Packaging and transport
The standard packaging is a 25-liter HDPE can for 25 kg peroxide solution or a 220-liter HDPE
drum for 200 kg peroxide solution.
LQ-DBHP is classified as Organic peroxide type F, liquid; Division 5.2; UN 3109; PG II.
。Application
LQ-DBHP may be used in mass ,emulsion and solvent (co)polymerizations of styrene, butadiene,
acrylonitile, acrylates and methacrylates. In emulsion processes, LQ-DBHP my be activated by
water-soluble as well as oil-soluble reducing agents or by metal compounds to achieve
reproducible polymerization at room temperature or lower.
LQ-DBHP is particularly suited for the cold emulsion polymerization of rubber latexes.
