NOVEL STABILIZERS FOR PVC/CPVC PIPE AND FITTINGS

Papers # 2018 Las-Vegas

PVC pipes and fittings are currently manufactured using a wide range of stabilizer systems whilst CPVC is currently manufactured using Tin stabilizers. The aim of this paper is to present a new type of heat stabilizer (booster) to be used in combination with Tin stabilizer; surprisingly this product offers synergistic effect with organotin stabilizers improving heat stability, it increases the softening point and allows a reduction of the formulation cost. The product can be also used as a building block in Calcium Organic Stabilizers (COS) for PVC and CPVC application; it improves the long-term heat stability and allows the most demanding technical requirements for injection molding of PVC and CPVC fittings to be achieved. The new substance is based on a non-toxic sodium salt of a dicarboxylic acid and complies with the most relevant regulation for food contact application.
