  • What are plasticizer performance tests?
  • Plasticizer performance tests include specifications including viscosity at 25 °C, density at 20 °C, chroma, acid value, and water content; processibility including plasticization efficiency, tensile strength, heat aging, low-temperature performance, fogging value, PVC compatibility, and UV aging.
  • What happens if the plasticizer content is increased?
  • An increase of the plasticizer content from 30 to 70% leads to a gradual decrease in the tensile strength and the 100% tensile modulus and the embrittlement temperature, as well as a gradual increase in the elongation at break and the vaporization loss and the dissolution loss.
  • What are the technical barriers to non-toxic plasticizer production?
  • Currently, the production of environmentally friendly, non-toxic plasticizers is facing two major technical barriers: (1) diverse side products and low yield; and (2) low production volume and high cost [135, 136].
  • What wt% plasticizer is used for ductility & elongation?
  • The stress–strain curves are shown in Figure 1a, where the plasticizer content was varied from 5 to 20 wt%. The films with 5 wt% plasticizer (GLY and DEA) exhibited slightly reduced strength and modulus, with increased ductility and ≈80% elongation at break.
  • Why are plasticizers important for synthetic resin processing?
  • Plasticizers are necessary additives for synthetic resin processing to improve the processibility. The current production volume of synthetic resins reaches 9.6 million tons per year, making China one of the major plastics production and consumption countries in the world.
  • Are primary plasticizers good for Environmental Protection?
  • Currently, the performance of primary plasticizers produced in China cannot fully satisfy the requirements for environmental protection, especially poor cleanliness and high toxicity. DOP and dioctyl adipate (DOA), especially the former, are the plasticizers widely used in PVC-based food wrap and packaging.
