PVC pipe is a pipe product with strong toughness, good heat resistance and good ductility. It is composed of upper, middle and lower layers. The upper layer of the PVC pipe is a layer of paint film, which plays the role of waterproof and anti-aging; the middle layer is a polyvinyl chloride layer, which is the main base layer; the lower layer is a back-coated adhesive. There are many types of PVC pipe specifications, because its uses can be divided into water pipes and line pipes, so there are many categories of products, so you must understand the specifications of PVC pipes when you buy.
PVC pipes can be divided into soft PVC drainage pipes and hard PVC pipes according to their different properties. The main difference is whether they contain plasticizers. PVC hoses contain softeners, have weak physical properties, are not easy to store, cannot withstand certain water pressure, and have a limited range of use. Therefore, soft PVC pipes are commonly used for ceilings, floors, and leather surfaces, and are often used as line pipes.
Rigid PVC pipes do not contain plasticizers, are easy to shape during the production process, are not easy to be embrittled, are non-toxic and pollution-free, have a long storage time, and have very good physical properties. Rigid PVC pipes are usually used as drainage pipes and water pipes, which have great development and utilization value.
