The material bases for raw PVC are ethylene and salt. Ethylene is manufactured from oil feedstock or LNG and chlorine manufactured from Natrium Chloride (salt). Ethylene and chlorine react to form vinyl chloride, a chemical gas which through polymerization produces PVC. The resulting product is a white powder. To increase the impact strength PVC for window profiles is mixed with an acrylic ester to form a copolymer. The copolymer is mixed with additives to improve
