  • Why are plasticizers replaced with a compatible & non-toxic ester plasticizer?
  • To avoid the negative effects caused by plasticizer migration and at the same time maintain the good properties of soft PVC, low-molecular-weight plasticizers were replaced with compatible and non-toxic ester plasticizers.
  • What is the tensile strength of a plasticizer?
  • The tensile strength was approx. 19 MPa, while the elongation at break was approx. 250% for all tested plasticizers at a concentration of 50 PHR. Furthermore, plasticizer migration studies showed that the synthesized plasticizers had excellent resistance to plasticizer leaching.
  • Are polymeric plasticizers effective?
  • Polymeric plasticizers are very effective in providing migration or extraction resistance. Within a given series of esters, branched plasticizers offer better extraction and migration resistance than linear plasticizers. The addition of plasticizers to a PVC product extends the lower useful temperature limit of the finished product.
  • What is the best plasticizer?
  • The best migration test result obtained was 70% lower than that for DEHP or DINP. The ester mixture that was found to be the most favorable plasticizer was characterized by good thermal and thermo-oxidative stability (5% weight loss temperature: 227.8 °C in air and 261.1 °C in nitrogen).
  • What are plasticizers used for?
  • Mainly used for PVC, plasticizers improve the flexibility and durability of plastic end products. They also act as softeners, extenders and lubricants. SONGWON offers a comprehensive range of PVC stabilizers and plasticizers. In our PVC application lab in Ulsan, Korea, we support customers with expert formulation and performance evaluations.
  • What is plasticizer efficiency?
  • The term plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and can be reported as a ratio of the slope of the hardness versus concentration for one plasticizer relative to the slope of that found for DEHP. The efficiencies for some of the more important plasticizers are included in Table 24.2.
