New non-toxic auxiliary heat stabilizer of calcium, zinc and rare earth
——Dibenzoylmethane（DIBENZOYL METHANE）

The main quality index:

PVC Nontoxic auxiliary heat stabilizer, and calcium / zinc, barium / zinc, rare earth elements and, by the company with domestic universities jointly developed a new generation of environmentally friendly PCV auxiliary heat stabilizer with β-diketonesclass auxiliary heat stabilizer, compared with the following characteristics:
(1), in the powdered calcium Zn heat stabilizer with auxiliary heat stabilizer of new β-diketones DBM-S instead of the traditional β-diketones auxiliary heat stabilizer, thermal stability performance is essentially the same, but the composite heat stabilizer stabilized PVC products stored discoloration significantly reduced, can significantly improve the weather resistance of PVC products.
(2), DBM-S, the new β-diketone auxiliary heat stabilizer, and powdered calcium zinc heat stabilizer synergy is good, good compatibility with PVC resin.
(3), new β-diketone auxiliary heat stabilizer DBM-S applies to powdered calcium Zn heat stabilizer, the application can be mass ratio of 1:1 instead of DBM and SBM.
DBM-S, the new β-diketone auxiliary heat stabilizer were toxic and heavy metal detection, detection by the EU SGS environmental safety standards, the product is non-toxic products; and its compounds, heavy metal content in full compliance with the EU ROHS Directive 2002/95/EC and follow-up amendments to the directive.
