Polymer production

Detailed description

Trigonox® 21-CH50 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-CH50 can be used for the polymerization of styrene at approximately 90°C. Trigonox® 21-CH50 has an activity comparable with dibenzoyl peroxide (Perkadox® L-W75). Typically, Trigonox® 21-CH50 is used in combination with initiators such as tert-Butyl peroxybenzoate (Trigonox® C).

Functions

  • Polymerization initiator

Applications

  • LDPE

Thermoset composites

Detailed description

Trigonox® 21-CH50 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-CH50 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-CH50 can be lowered by the use of metal salts such as cobalt octoate.

Functions

  • Curing agent

Applications

  • Vinylesters

Acrylics production

Detailed description

Trigonox® 21-CH50 is an efficient initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 65-100°C, amongst others for the manufacture of coatings. Trigonox® 21-CH50 can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates.

Functions

  • Polymerization initiator

Applications

  • Acrylics
