The auxiliary heat stabilizer sf-50 (SBM) of I - diketone PVC is mainly suitable for composite calcium zinc and rare earth heat stabilization system. It has the effect of inhibiting initial coloring, preventing "zinc burning" and improving heat stability. It has good synergistic effect with auxiliary heat stabilizers such as epoxy soybean oil and phosphite. It can also be used directly as the main stabilizer or as the auxiliary stabilizer in combination with zinc soap, zinc phosphite, etc. Compared with DBM and SBM 55P, sf-50 has higher stability and more significant color inhibition ability in the later stage. Due to the high purity of sf-50, the recommended dosage is less than 55P and DBM. The recommended dosage is about 3% - 5% of the main stable dosage of calcium, zinc soap or rare earth soap. The actual dosage is determined by the user through experiments.Thermal stability: very good thermal stability. No fumes are given off during the compound processing.
