Trigonox® 289-IN VRN is a special peroxide blend with a VR system, suitable for curing unsaturated polyester and vinylester resins at ambient conditions in conjunction with a metal accelerator.

Perkadox® GB-50L is a free-flowing 50% peroxide formulation on a phthalate-free carrier for curing unsaturated polyester resins and (meth)acrylic resins at ambient and elevated temperatures. Provides excellent solubility in standard thermoset curing applications.

Trigonox® 77C is a special peroxide blend used for high-temperature curing.

Trigonox® 63 is a peroxide mixture with MEKP and acetylacetone peroxide for curing unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. Faster than Trigonox® 61 and Butanox® M-50, slower than Trigonox® 44B.

Trigonox® 101-50D-PD is a 50% formulation on an inert carrier sytem in powder form.

Trigonox® 421 is an initiator for (co)polymerization of ethylene, styrene, (meth)acrylates and polyols.

Trigonox® 21LS is a peroxide formulation used for curing unsaturated polyester resins at elevated and high temperatures.

We offer azo initiators, such as Perkadox® AIBN (azobisisobutyronitrile) and Perkadox® AMBN (2-methylbutyronitrile), for bulk, solution, suspension and emulsion polymerization of a wide variety of monomers, such as styrene, vinylchloride, vinylidenechloride, acrylonitrile, acrylates and methacrylates. Our most commonly used initiator is AIBN, but our AMBN provides even better solubility than AIBN.
Advantages of AIBN initiators: Azo initiators have many advantages over standard organic peroxides, such as the fact that they form no oxygenated byproducts and provide low yellow discoloration. Azo initiators generate only C-centered radicals, which are low energy and very selective and cause a low amount of branching. This provides low Poly Dispersity Index (PDI) values and molecular weights.
Perkadox® AIBN does not form oxygenated residues and does not cause oxidative degradation of pigmented of dyed polymer systems. For this reason, the color stability or transparent, dyed polymers, such as polymethylmethacrylate, is improved.
AIBN and other azo initiators provide excellent color stability in transparent colored polymers, such as PMMA. They do not form oxygenated residues and do not cause oxidative degradation of pigmented or dyed systems.
Compared with organic peroxides, azo initiators avoid excessive grafting, making them particularly suitable for use in manufacturing acrylic cast and moulded sheets, as well as adhesives, acrylic fibers, super absorbers, detergents and flocculants. Our most commonly used initiator is AIBN, but our AMBN provides even better solubility than AIBN.
Perkadox® AIBN can also be used for pharmaceutical and fine organic synthesis.
Our Trigonox 421 provides similar technical performance and is a sustainable alternative for AIBN. An additional advantage of Trigonox 421 is that all decomposition products that are generated are non-toxic, which is in contrast to AIBN which forms toxic TMSN.

Trigonox® 22-CH50 is a special peroxide for smooth curing of unsaturated polyester resins at elevated and high temperatures.

The application for Perkadox® 33 SP is the bleaching of flour, oil, whey & cheese products.
