Application Scenarios
Synthetic Leather Industry
DMF is a key solvent for PU synthetic leather production. It dissolves polyurethane resin in the wet process to form porous and flexible base layers for artificial leather. Our high purity DMF guarantees smooth finished leather for shoes, bags and furniture upholstery, perfectly matching mass production lines of synthetic leather manufacturers.
Pharmaceutical & Agro chemical Intermediates
DMAC, formamide, methyl acetate and ethyl acetate serve as high polarity solvents for organic synthesis of pharmaceutical API and pesticide intermediates. They boost reaction efficiency and support extraction & recrystallization processes. Stable grade raw materials help customers avoid impurity risks for fine chemical production.
PU Resin Manufacturing
DMF and DMAC dissolve polyurethane raw materials for PU resin polymerization and formulation. Anhydrous ethanol and ethyl acetate work as co solvents to adjust viscosity and evaporation speed. Our consistent quality chemicals support large batch production of PU adhesive, coating and ink resins.
