Characteristics

[Close]

DOA is a cold resistant plasticizer with superior heat and light stabilities, and also has good machinability.
Plastisol blended with DOA has low initial viscosity, so it gives good fluidity, and there is no rapid increase of viscosity during storage (25℃). The plastisol blended with DOA also has high viscosity yield value. The apparent rise of viscosity when blending with high speed rotation or spread coating is also low.
