VISIOMER® – METHACRYLATE MONOMERS AS CO-AGENTS FOR ELASTOMERS WITH PEROXIDE OR RADIATION CROSSLINKING

Application Areas

VISIOMER®
Crosslinking agents traditionally used for vulcanization, such as sulfur donors, only work with unsaturated polymers. Saturated elastomer polymers need to be crosslinked by means of energy-rich radiation or peroxides, which can also be used for crosslinking unsaturated polymers.
Compared to sulfur vulcanization, peroxide or radiation crosslinked technology improves thermal stability and ozone resistance in the end product. Using co-agents in conjunction with peroxide to cure elastomers makes it possible to reduce the content of costly peroxides. This way, crosslinking density and curing speed can be accelerated as well.
Those co-agents are typically multifunctional monomers that are highly reactive in the presence of free radicals and graft to elastomer chains, forming a complex crosslinked network. Depending on the desired crosslinking density, they are typically used in quantities of 0.5 to 5 wt. % in the polymer.
Typical application fields:
  • Wire and cable insulation, cable jacketing
