PVC melting temperature during processing is a very important process parameter, if this parameter will lead to improper decomposition of the material. PVC flow characteristics are quite poor, its process range is very narrow. Especially large molecular weight PVC material is more difficult to process (this The material is usually added to the lubricant to improve the flow characteristics), so usually used are small molecular weight PVC material PVC shrinkage is quite low, generally 0.2 to 0.6%.s
