Chemical Structure 

Application 

Di-tert-amyl peroxide ,primarily used as an initiator for the production of low-density polyethylene (LDPE) and acrylic resins. 

Its ability to effectively initiate polymerization makes it valuable in various industrial processes, particularly in the plastics and coatings industries.

● Controlled rheology polypropylene (CR-PP) in an extrusion process :

XJ-DTAP allows great flexibility in controlling the melt flow index (MFI) of polypropylene. Small changes in either peroxide concentration or process temperature can produce significantly different MFIs. 

The MFI increases with the peroxide level.

● Polymerization of ethylene :

 XJ-DTAP is used for high pressure polymerization of ethylene in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity.

● Polymerization of styrene :

XJ-DTAP may be used in polymerization and copolymarization of styrene. In a mass process it can be used to increase polymerization rates.

● Polymerization of acrylates and methacrylates :

XJ-DTAP can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates.

●  Curing of unsaturated polyester resins

XJ-DTAP is used for the curing of unsaturated polyester resins at elevated temperatures, in the temperature range from 120° to 160°C. It is used in polymerization of alkyde styrene resins too.
