Best Applications for Polymeric Plasticizer in Cable Insulation
Best Applications for Polymeric Plasticizer in Cable Insulation Polymeric plasticizers are high-molecular-weight PVC additives that deliver superior permanence, low migration, and exceptional resistance to extraction—making them the preferred choice for demanding cable insulation applications where conventional phthalates fall short. Key Takeaways Polymeric plasticizers excel in high-temperature cable applications where migration and volatility cause premature insulation failure. Their large molecular structure provides outstanding resistance to oil, solvent, and water extraction—critical for industrial and automotive wiring. Applications range from welding cable insulation to submersible pump cables, each demanding specific permanence and flexibility properties. Polymeric plasticizers reduce plasticizer loss over time, maintaining electrical and mechanical properties far longer than monomeric alternatives. While higher in cost than standard phthalates, their extended service ...
