Balancing Plasticizer and Support in PVC Formulation The loss of support from excessive plasticizer is a classic trade-off in PVC formulation. To regain mechanical strength without fully sacrificing low-temperature flexibility, consider these integrated adjustments: Partial Replacement: Substitute a portion of the primary plasticizer with a polymeric or secondary plasticizer (e.g., DOTP, DINCH). These often offer better permanence and less softening efficiency. Reinforcement: Incorporate low-loa

Influence of Ambient Temperature on Plasticizers 1. Migration and Volatility Higher Temperatures: As ambient temperature increases, the plasticizer molecules gain more kinetic energy. This can lead to increased migration of the plasticizer to the surface of the material and higher volatility (evaporation). Over time, this causes the material to lose flexibility, become brittle, and potentially shrink or crack. Lower Temperatures: At colder temperatures, migration and volatility slow down, keepin

Why can plasticizer DOP be applied in the medical industry? The application of plasticizer DOP (dioctyl phthalate) in the medical industry is mainly based on its excellent physical and chemical properties, but in recent years it has been gradually restricted or replaced due to its potential health risks. Reasons for the application of DOP in the medical industry 1. Excellent plasticizing effect DOP is well compatible with polymer materials such as polyvinyl chloride (PVC), significantly increasi
