Market Segments

Polymer production

Detailed description

Trigonox® 21S 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. In suspension polymerization processes, Trigonox® 21S can be used for the polymerization of styrene at approximately 90°C. Trigonox® 21 has an activity comparable with Dibenzoyl peroxide (Perkadox® L-W75). Typically, Trigonox® 21S is used in combination with initiators such as tert-Butyl peroxybenzoate (Trigonox® C) and tert-Butylperoxy 2 ethylhexyl carbonate (Trigonox® 117).

Functions

  • Polymerization initiator

Applications

  • LDPE,
  • Polystyrene

Thermoset composites

Detailed description

Trigonox® 21S, tert-Butyl peroxy 2 ethylhexanoate, is a perester which is used for the curing of unsaturated polyester resin at elevated and high temperatures. Trigonox® 21S is preferred for the curing of UP resin based Hot Press Molding formulation (such as SMC and BMC) in the temperature range of 120 - 160°C. As Trigonox® 21S is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC. In combination with a cobalt accelerator, Trigonox® 21S is also applicable for the cure of UP resins in the temperature range of 60°C and higher. Application area can be air drying lacquers, diplacquers, wall panels, filament winding, etc.

Functions

  • Curing agent

Applications

  • Hot press molding,
