Methylene Diphenyl Diisocyanate (MDI) is a highly versatile chemical compound used in the production of polyurethane foams, adhesives, coatings, and elastomers. It is a diisocyanate, meaning it contains two isocyanate (-NCO) functional groups that react with other compounds containing hydroxyl (-OH) groups to form polyurethane polymers.
MDI is a light yellow to brownish liquid with a characteristic odor. It is primarily used in the production of rigid polyurethane foams for insulation in construction and refrigeration applications, as well as in flexible foams for cushioning and comfort applications.
MDI is also used in the production of adhesives and sealants, coatings, elastomers, and other specialty polyurethane products. It is valued for its high strength and durability, as well as its resistance to heat, chemicals, and moisture.
However, MDI can be hazardous if not handled properly, and exposure to MDI can cause irritation to the eyes, skin, and respiratory system. Therefore, proper protective measures and handling procedures should be followed when using MDI.

Toluene diisocyanate (TDI) is a colorless to pale yellow liquid that is used primarily in the production of flexible and rigid polyurethane foams. It is a highly reactive chemical compound that contains two isocyanate functional groups. TDI is produced by reacting toluene with phosgene to form a diisocyanate intermediate, which is then purified to obtain the final product.
TDI is a versatile chemical with a range of applications beyond polyurethane foam production, including as a binder in wood products, as a coating and adhesive in the automotive industry, and as a pesticide. However, it is important to handle TDI with care as it is a potent respiratory irritant and can cause asthma and other respiratory problems if not properly controlled.
Epimon DMCC is a reliable supplier of TDI and can provide high-quality products to meet the needs of various industries. Our team has extensive knowledge and experience in the handling and transport of TDI to ensure safe and timely delivery to our customers.
