Dibenylmethane diisocyanate, referred to as "MDI", is an organic substance, a chemical formula C15H10N2O2, white to light yellow molten solid, 4,4'-diphenyl diisocyanate, 2,4'-diphenyl diisocyanate, 2,2'-diphenyl methane isocyanate isomer.

use:

1. Pure dibenylmetane diisocyanate is usually supplied with melting condition (small sale), pure dibenzyl diisocyanate is mainly used in reactive injection molding (RIM) composite, thermoplastic elastomers (JPU) pouring elastomers and spandox Elastic fiber. Diphenyl diisocyanate is modified, widely used as a strong coating, adhesive, sealant, and the like.

2. Diphenyl diisocyanate is a major raw material for producing polyurethane elastomers, polyurethane products made of diphenyl methane diisocyanate because of high tear strength, low temperature softness, low thermal conductivity, and more Stability, etc., is widely used to produce polyurethane synthesis leather, artificial leather coatings, polyurethane soft bubbles, hard foam, etc., especially for building materials.

3. The dibenylmetane isocyanate is more than 90% of the polyurethane material. The application field is expanding, such as RIM elastomers, thermoplastic polyurethane elastomers, polyurethane sealing paints, dibenzyl diisocyanate polyurethane, polyurethane tape, acrylate polyurethane Elastomer and synthetic leather, etc., new products are being developed continuously.
