Application Of Pentamethyl-Diethylene-Triamine

WHAMINE Pentamethyl-Diethylene-Triamine (PMDETA) is a polyurethane reaction of highly active catalysts, catalytic main foaming reaction. Pentamethyl-Diethylene-Triamine(PMDTA) is used to balance the overall foaming gel reaction, which is widely used in all kinds of polyurethane rigid foam, including different cyanuric acid ester rigid plank. Because of its strong foaming effect, Pentamethyl-Diethylene-Triamine (PMDT) can improve the liquidity bubble, so improving production technology and improve the quality, often Shared with DMCHA etc;

Except for rigid formula, methyl divinyl three amine five also can be used in polyether type of polyurethane soft piece of bubble and foam molding production, for example, 70 % Pentamethyl-Diethylene-Triamine (PMDETA) is mainly used for soft foam products are formulated, the catalyst activity, foaming speed, products with high toughness and high carrying.
