Stabilizers for polymers Whatsapp:+86-13553089896 PVC thermal stabilizers function mainly by substitution of the labile allylic chlorine atoms that are intermediates in the dehydrochlorination process. By this mechanism they significantly enhance the heat stability of the polymer during both melt processing and end use. Qingdao PMST Chemical co.,Ltd provides thermal stabilizers for PVC designed for use in applications such as automotive interior and exterior components, film and sheet, calendering, extrusion, injection molding, and others. In demanding applications like wire and cable insulation, pipe, and window profile, thermal stabilizers based on lead salts have been used for many years. These products can be highly effective thermal stabilizers, but their use is being phased out around the world due to the well established toxicity of lead and its salts.  Whatsapp:+86-13553089896 Skype:frank99886600  Email:  hakingroup@foxmail.com    fran...
