Polyvinylchloride, ingredient for polyvinyl chloride, bright color,
corrosion resistance, durable, due to the increase in manufacturing
process of plasticizer, anti-aging agents some toxic auxiliary
materials to enhance its heat resistance and toughness, and
extendibility, so its products are not for food and medicine. It is

world scope get production and application. In recent years the
rate of growth of PVC in southeast Asia is especially significant,
thanks to southeast Asian countries have in infrastructure
construction of urgent needs. Can production in 3 d surface film of
materials, PVC is the most suitable materials. PVC (PVC), the
