Sundly's main patented products are Mg/Al/Zn (Ca/Zn) non-toxic complex stabilizers. Our stabilizers are widely used in environmental friendly PVC products(flexible, rigid,calendered), such as calendered sheets (high transparent), calendered film, high transparent flexible products, foam sheets, WPCs,SPCs, toys, wires and cables, shoe materials, profiles, pipes, injection molding parts, etc. Our products are in compliance with RoHS and REACH standards. In 2018, our new project Mg/Al/Zn non-toxic complex stabilizer for high transparent rigid calendered PVC products passed the China national science and technology achievement appraisal. The appraisal committee agreed that "the overall technology of the project has reached the international advanced level." This stabilizer can replace organotin stabilizers to produce high transparent rigid calendered PVC products. Its weather ability is better and it can reduce product costs. It is an eco-friendly PVC heat stabilizing auxiliary.
