Application
1. Polymerization of styrene
TBEC can be used for the polymerization and
co-polymerization of styrene in the temperature range of 100-130℃. in a mass process,
TBEC can be advantageously used to increase polymerization rates.
2. Polymerization of acrylates and methacrylates
TBEC can be used as initiator for the solution
(co)polymerization of acrylates and methcrylates in the temperatures range of 100-170℃, amongst others for the coatings.
TBEC can also be applied as an initiator for the bulk and suspension
(co)polymerization of acrylates and methcrylates.
3. Peroxides for Thermoset Resins
TBEC, tert-butylperoxy 2-ethylhexyl carbonate, is an aliphatic perester that is used for the curing of unsaturated polyester resins at elevated temperatures
