PVC Paste Resin For Dip Molding Industry

PVC Paste Resin For Dip Molding Industry Property The synthesis of vinyl chloride mainly includes calcium carbide method and petroleum. There are two methods. The calcium carbide method is lower in cost than the petroleum method, but the quality of the vinyl chloride monomer produced by the calcium carbide method is slightly worse than that of the petroleum method. At the same time, the calcium carbide method causes greater pollution, but at the same time, the petroleum method also has costs caused by rising oil prices. Fluctuation issues, so companies that can control upstream raw materials have more advantages in cost control. Micro-suspension polymerization is a relatively new method for preparing PVC paste resin, which was industrialized as early as the mid-1960s. The process is: first part of the VCM (5%) is made into a stable emulsion (with a particle size of about 1.0μm) by mechanical homogenization, and then polymerized (an oil-soluble initiator must be selected…
