PVC products are made with PVC molds made through special injection molding machines. PVC raw material ingredient for polyvinyl chloride (PVC), bright color, corrosion resistance, solid and durable, due to the increase in the process of manufacturing the strengthening agent, inhibitor and some other poisonous auxiliary material to enhance its heat resistance, robustness, ductility, etc., so the PVC products generally do not store food and medicine. Is a popular and widely used synthetic material in the world. Its global use ranks third among synthetic materials.

So what are PVC suitable for? At present, the largest market is PVC pipe fittings, which is also the most common in PVC mold. Because of its corrosion resistance and aging resistance, it is suitable for products with long service life. But some customers say the PVC is toxic, cannot make other food grade products, PVC itself is, in effect, no poison, mainly the additive agent, most of the PVC on the market has to use additives, can be more smooth in production, have toxic and nontoxic additives, especially the stabilizer, opaque with lead salt, cadmium salt, barium salt is toxic, other non-toxic. The other RIPS are the same, both toxic and non-toxic.

Like PVC sheet material used on drug packaging, the disposable infusion tube is all PVC. PVC thermal stability is not very good, heat decomposition, but at least also want to around 170 degrees temperature, and light will not cause decomposition of PVC, the current building drain connection also is all PVC mold injection molding processing, so it is not very stable and highly accurate. Decomposition is the production of HCL, the smell is very pungent, usually only in the production process, the use will not appear.
