Methylene Diphenyl Diisocyanate (MDI): MDIs are manufactured with the phosgenation of the condensation product of aniline with formaldehyde. The most typical isomer used in polyurethane generation is purified four,four isomers. MDIs are commonly used in generating rigid and semi-rigid polyurethane foams.

Tear Resistance: This is actually the force needed to split the foam having a puncture or slit at one facet. The notion of measuring the force is analogous for the tensile strength take a look at.
