MDI Applications
Isocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, PU coating, PU adhesive,
Seepage-proofing, structure foam, Automobile bumper, high resilience etc.
With good performance such as very good fluidity, very good foaming capacity, strength well, dimension stability etc.
