Product Description
Hydrotalcite is a white mineral having a layered structure found in nature with a general chemical formula of Mg6Al2(OH)16CO3.4H2O. PVC is decomposed during processing from heat and the shear stress effects and is decomposed by the effect of UV rays while it is in final product form, resulting in the Cl in its structure being released. Cl, which is released into the medium in the form of an HCl gas, may cause the PVC first to turn yellow and then to burn out. The most important functions expected out of the stabilizers is to chemically react with the HCl which has been released. Hydrotalcites are very effective in PVC stabilization because they are very good acid scavengers due to their exceptional anion-exchange properties. Hydrotalcites have greatly enhanced the performance of Ca/Zn-based stabilizer systems, due to their features of environmentally friendliness and non-toxicity. They particularly have a major share in the development of stabilizers used in the production of rigid PVC window profiles and flexible PVC automotive cables with high service temperatures. At Akdeniz Chemson, we have 2 types of hydrotalcite products. -AS-01 (Magnesium Aluminium Hydroxycarbonate Hydrate) -AS-04 (Magnesium Zinc Aluminium Hydroxycarbonate Hydrate)
