As a professional distributor of polyurethane raw materials, we supply top-grade TDI (Toluene Diisocyanate) and MDI (Methylene Diphenyl Diisocyanate) to meet the diverse needs of industries worldwide. These essential isocyanates serve as key building blocks in the production of polyurethane foams, elastomers, adhesives, coatings, and sealants.

TDI (Toluene Diisocyanate)

TDI is a highly reactive aromatic diisocyanate primarily used in the production of flexible polyurethane foams. It plays a important role in whole polyurethane industry.

Applications:

• Furniture and bedding foams

• Automotive seat cushions

• Packaging and insulation foams

• Elastomers, adhesives, and sealants

Available Grades: TDI-80

MDI (Methylene Diphenyl Diisocyanate)

MDI is a versatile aromatic diisocyanate used in the production of rigid, semi-rigid, and flexible polyurethane products. It provides superior mechanical properties, thermal insulation, and durability.

Applications:

• Rigid foam for refrigeration and construction

• Automotive interior and NVH components

• Footwear, sports equipment

• Industrial adhesives and coatings

Available Types:

1. Pure MDI (4,4'-MDI)

2. Polymeric MDI (PMDI)

3. Modified MDI for specific system requirements

HDI (Hexamethylene Diisocyanate)

HDI is an aliphatic diisocyanate known for its excellent weatherability, UV resistance, and color stability. It is widely used in high-performance coatings that demand long-term durability and appearance retention.

Applications:

• Automotive refinishing and OEM coatings

• Industrial and marine coatings

• Polyurethane topcoats and clear coats

• Elastomers and specialty adhesives

Available Types:

1. HDI monomer

2. HDI trimer (isocyanurate type)

3. HDI biuret
