Uses of Triethylene glycol diisocitate 
This product is a solvent-based cold-resistant and environmentally friendly plasticizer, which has excellent low temperature, durability, oil resistance, ultraviolet radiation and anti-static properties, and has low viscosity and certain lubricity. This product is a special plasticizer for polyvinyl butyral (PVB safety glass) and synthetic rubber, which can produce low temperature performance and low volatility. It can also be used in polyester cloth, binders and sealing materials, and is a plasticizer for PVC, PS, ethyl cellulose, nitric cellulose, etc. When used in polyvinyl butyral cloth-based coatings containing castor oil, it can improve flexibility in severe cold conditions. It is also used in the formulation of butadiene-acrylic oil-resistant synthetic rubber and polyethylene latex paint, and the amount is generally lower than dioctyl phthalate or trithylyl phosphate. Soluble in many organic solvents, but insoluble in mineral oil.
