Process & Logistics & Packaging
Bluerox 63S is preferred for the curing of UP resin based Hot Press Molding formulation (such as SMC and BMC) in the temperature range of 120 - 160°C. As Bluerox 63S is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC. In combination with a cobalt accelerator, Bluerox 63S is also applicable for the cure of UP resins in the temperature range of 60°C and higher. Application area can be air drying lacquers, diplacquers, wall panels, filament winding, etc. Bluerox 63S is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range. In suspension polymerization processes, Bluerox 63S can be used for the polymerization of styrene at approximately 90°C. Bluerox 63S has an activity comparable with Dibenzoyl peroxide. Typically, Bluerox 63S is used in combination with initiators such as tert-Butyl peroxybenzoate (Bluerox 60) and tert-Butylperoxy 2 ethylhexyl carbonate (Bluerox 40).
