MDI vs TDI Selection Guide

李思涵

Comparative analysis of MDI and TDI chemical properties, applications and cost factors to help select the right isocyanate type.

MDI vs TDI Selection Guide

Choosing the right isocyanate type is crucial for product performance. This article compares the chemical properties, applications, and cost factors of MDI and TDI.

Chemical Structure Differences

MDI has higher molecular weight and lower vapor pressure, offering better handling safety than TDI. TDI has higher reactivity, suitable for fast-curing processes.

Application Comparison

MDI is widely used in rigid foam insulation boards, spray foam and adhesives; TDI is mainly applied in flexible furniture foam and automotive seating.
