Pultrusion

Typically used in elevated temperature molding processes such as SMC, BMC, and Pultrusion.

Norox TBPB is a highly efficient source of free radicals at moderate to high temperatures and can be used as a polymerization or co-polymerization initiator to produce polyethylene, polystyrene and polyacrylates.

It is an effective medium temperature initiator for the polymerization and/or crosslinking of numerous monomers and resins, including unsaturated polyester and vinyl ester resins.

Norox Pulcat AW can also be used in cobalt promoted resins for ambient temperature cures.

Norox P-20 is an efficient moderate to high temperature initiator for the polymerization of monomers and resins with vinyl unsaturation.

Norox 802-75P is an excellent product for use in elevated temperature molding in the range of 210°F – 300°F (100°C – 150°C).

Norox 500-75P is an efficient source of free radicals in the curing or crosslinking of unsaturated polyester and vinyl ester resins.

This cycloaliphatic peroxydicarbonate is used as an initiator (radical source) in the polymerization of monomers, such as vinyl chloride and methacrylates.  It is also widely used in curing unsaturated polyester resins, particularly in pultrusion applications.

NOROX 425 is an excellent free radical source (initiator) in the polymerization of monomers, especially styrene and is recommended for use in the elevated temperature curing processes for unsaturated polyester and vinylester resins as the “high-range” initiator.

Norox 415 is especially useful in the temperature range of 180°F to 275°F (82°C - 135°C) in a number of elevated temperature cure processes utilizing unsaturated polyester resins, including BMC, wet-mat molding, preform molding, filament winding, and CIPP.
