Focusing on solving the heavy metal pollution problem of traditional lead salt stabilizers, this product adopts a composite calcium-zinc system paired with food-grade additives, paired with antioxidants to extend thermal stability time, with excellent dispersibility to avoid precipitation problems during PVC processing. It complies with multiple national food safety certifications such as FDA and GB, optimizes the processing fluidity of PVC products, reduces energy consumption, has no odor residue, fully meets the safety requirements of food contact scenarios, and can improve the service life of products by more than 15% compared with similar products.
Detailed parameters: the appearance is white free-flowing powder, with a density of 1.58 g/cm³, thermal stability time of 15 minutes at 180℃, suitable for rigid PVC systems, volatile content ≤0.3%, heavy metal content ≤10 ppm, packaging specification of 25 kg per bag, shelf life of 12 months, applicable processing temperature range of 160-200℃, excellent dispersibility, compatible with various PVC processing aids, free alkali content ≤0.1%, suitable for twin-screw extrusion, injection molding and other processing technologies.
It is suitable for food-contact rigid PVC products, including food fresh-keeping boxes, disposable tableware, food-grade water pipes, beverage bottle packaging and other scenarios, and can also be used for non-invasive medical device shells, children's toy shells (food contact grade) and other PVC products that require strict safety certification, meeting the food contact material safety standards of Europe, America and China, helping producers quickly pass compliance testing.
