Initial yellowing problem of PVC extruded products

The initial coloring control of calcium-zinc stabilizers requires the synergistic cooperation of multiple auxiliary stabilizers such as β-diketones and epoxidized soybean oil; through formulation optimization and processing temperature adjustment, initial yellowing can be effectively suppressed.
