Market Segments

Polymer production

Detailed description

Trigonox® 21-CL50 is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range. Polymerization of styrene: In suspension polymerization processes, Trigonox® 21-CL50 can be used for the polymerization of styrene at approximately 90°C. Trigonox® 21-CL50 has an activity comparable with dibenzoyl peroxide (Perkadox® L-W75). Typically, Trigonox® 21-CL50 is used in combination with initiators such as tert-Butyl peroxybenzoate (Trigonox® C).

Thermoset composites

Detailed description

Trigonox® 21-CL50 is a suitable initiator for the curing of unsaturated polyester, vinyl ester and acrylic thermosetting resins in the temperature range of 100-140°C (212-284°F). Trigonox® 21-C50 is the classic intermediate initiator for pultrusion applications, and also finds wide use in molding compounds and cured-in-place pipe systems. The activation temperature of Trigonox® 21-CL50 can be lowered by the use of metal salts such as cobalt octoate.

Functions

  • Curing agent

Applications

  • Unsaturated Resin,
  • Vinylesters
