Polyurethane Catalysts

Tosoh's catalysts are efficient as well as reliable for polyurethane foam formation.

Tosoh can modify these products to meet even the most demanding production conditions worldwide.

Triethylenediamine 1,4-Diazabicyclo[2,2,2]octane

TEDA is a white, solid crystalline tertiary amine compound. TEDA is used extensively as a catalyst to promote both gelling and blowing reactions in the production of flexible, semi-rigid and rigid polyurethane foams as well as elastomers and adhesives. TEDA is available in solutions of dipropylene glycol (L33), ethylene glycol (L33E) and 1,4-butanediol (L25B).

Toyocat is the trade name of Tosoh's specialty amine catalysts for polyurethanes. A broad range of Toyocat products are available including conventional catalysts, reactive catalysts, acid-blocked catalysts, and trimerization catalysts. Specialty grades are available to meet the requirements of a variety of polyurethane applications; e.g. SPF series for flexible molded foams, HX series for semi-rigid foams, B series for rigid foams and F series for CFC reduction foams.

A summary of the main characteristics:

  • There is no occurrence of volatile organic compounds (VOC) due to the urethane foam catalyst.
  • Since there is no generation of VOC, it is possible to suppress the odor of specific urethane resin, and solves the problem of discoloration of peripheral resin (PVC resin, such as polycarbonate resin).
  • Also, it is possible to manufacture urethane resin that has the durability to existing catalysts, which was considered difficult for environmentally friendly urethane blowing catalysts.
