  Performance and purpose:
   This product is oily transparent liquid with light aura. The molecular formula is C24H38O4 and the molecular weight is 390.5. The relative density (d2020) is 0.986 and the solubility is ≤0.01% ( 25℃ ) . This product is a widely used plasticizer with combination property and has the good compatibility with PVC, synthetic resin, pyroxylin and rubber. It is used for the processing of many PVC soft plastic, such as film, leatheroid, wire, cable, rubber and plastic. It's widely used in the industries of rubber, paint and emulsifier and can improve the rebound elasticity of products and reduce the permanent distortion and has no effect on the sulfuration of sizing.
