Which part plays a major role in reducing the hardness of PVC compound either Plasticizer or Stabilizer or Resin grade too ? How to achieve 60 Shore A PVC Compound ?
Results with discussions are welcome.
plasticizers obviously (kind and quantity), and fillers and K resins with less impact. What kind of plasticizer do you want to use for getting 60 ShA?
