PC 300 is widely used as a high-performance plasticizer in the production of polyvinyl chloride (PVC) and other polymeric materials. It enhances flexibility, workability, and durability in rigid polymer systems, making it ideal for applications in wire and cable insulation, flooring, and automotive interiors. Due to its excellent low-temperature performance and resistance to heat aging, PC 300 is preferred in outdoor and high-stress environments. It also improves processability during extrusion and molding, reducing production energy and improving output efficiency. Additionally, it is employed in synthetic rubber and adhesive formulations to modify tack and elongation properties.
