Industry knowledge:
Stearoylbenzoylmethane (SBM) PVC stabilizer is a formaldehyde-based polymer used in PVC to prevent degradation.
Stearoylbenzoylmethane (SBM) is a type of plasticizer and stabilizer that is used in producing most flexible vinyl plastics. SBM is an efficient UV stabilizer, lubricant and antioxidant, which makes it an excellent additive for CDs, DVDs and other products requiring protection from the sun’s rays.
This additive is more effective than other stabilizers in preventing PVC degradation. Its excellent stability in normal ambient temperature makes it suitable for baby powder, cleaners, cosmetics and adhesives applications.
