LUPRANATE 5143
LUPRANATE 5143
Carbodiimide-Modified Isocyanate
Lupranate 5143 isocyanate is a liquid, carbodiimide-modified 4,4-diphenylmethane diisocyanate. With manufacturing advances, Lupranate 5143 isocyanate achieves better low temperature stability than Lupranate MM103 isocyanate. At the same time, Lupranate 5143 isocyanate offers consistently low color and improved stability in formulated products such as prepolymers and casting kits. Lupranate 5143 isocyanate is a viable alternative to Lupranate MM103 isocyanate in CASE and microcellular urethane applications.
