Polyvinyl chloride resin is a multi-component plastic, depending on the application can be added to different additives, so with the composition of different products can show different physical and mechanical properties, such as adding or without adding plasticizer can make it There are hard and soft products of the points. In general, PVC products are resistant to chemical stability, flame self-extinguishing, wear, muffler shock, high strength, good electrical insulation, low cost and wide material source, good air tightness and so on. The shortcomings of poor thermal stability, by the light, heat, the role of oxygen easy to aging. Polyvinyl chloride resin itself is non-toxic, if the use of non-toxic plasticizers, stabilizers and other auxiliary materials made of products, harmless to humans and animals. However, generally seen in the market of PVC products used plasticizers, stabilizers are mostly toxic, so in addition to marked non-toxic formula products, can not be used to dress food.
