Polymerization of styrene:
PEROXAN BIC may be used in polymerization and copolymarization of styrene.
In a mass process PEROXAN BIC can be used to increase polymerization rates.In suspension polymerization processes, PEROXAN BIC is often used for reduction of residual styrene content during the final polymerization stage. PEROXAN BIC is a benzene-free replacement of tert-Butyl peroxybenzoate (PEROXAN PB).
Temperature range: 95 to 125°C
Dosing: 0,02 to 0,1 phr
Polymerization of acrylates and methacrylates:
PEROXAN BIC can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates.
Temperature range (solution polym.): 100 to 170°C
Dosing: 0,1 to 1 phr
PEROXAN BIC is used for the curing of unsaturated polyester resins at high temperatures.
PEROXAN BIC is preferred for the curing of UP resin based hot press moulding formulations in the temperature range from 140° to 160°C.
PEROXAN BIC gives a long shelf life stability of the compound.
PEROXAN BIC - in comparison with PEROXAN PB, tert-Butyl peroxybenzoate, - can be caracterized as a faster and more efficient peroxide. This means a faster and more optimal cure with a lower residual monomer content of the moulded part.
The decomposition products of PEROXAN BIC are low volatile compounds, which make the peroxide very suitable for production of e.g. microwave cookware.
Depending on application and working conditions, the following peroxide and when applicable cobalt accelerator dosage levels are recommended:
PEROXAN BIC: 1,0 to 2,0 phr
