Polyurethane Catalysts

Tri-iso distributes a wide range of catalysts that allow formulators to produce high quality polyurethane systems.  Catalysts are chemicals that reduce the energy of activation, allowing reactions to occur faster and at lower temperatures than otherwise possible.  Catalysts do not directly participate in the reaction, and remain unchanged in the system once the reaction is complete. 

Catalysts for polyurethane systems can be divided into two broad classes: gelling catalysts and blowing catalysts.  Gelling catalysts are more selective to catalyzing the reaction of the isocyanate with hydroxyl groups, whereas blowing catalysts are foaming catalysts; Blowing catalysts are more selective to catalyzing the reaction of the isocyanate with water to produce foam.  When formulating a polyurethane foam system, it is important to have the correct ratio of gelling and blowing catalysts.  If the ratio of gelling and blowing catalysts is incorrect, the foam will either lack physical integrity, or will be too dense.

Tri-iso distributes polyurethane catalysts based on tin carboxylates, amines, bismuth carboxylates, zinc carboxylates, zirconium carboxylates, and nickel carboxylates.
