Overview of relevant knowledge of PVC plastic hose

VC hose is a kind of pipe product with strong toughness, good heat resistance and good ductility. It is composed of upper layer, middle layer and lower layer. The upper layer of PVC pipe is a layer of paint film, which plays the role of waterproof and anti-aging; The middle layer is PVC layer, which is the main base layer; The lower layer is back coated with adhesive. There are many specifications and models of PVC pipe. Because its uses can be divided into water pipe and line pipe, there are many product classifications.

Specification and classification of PVC pipe: PVC pipe can be divided into soft PVC pipe and hard PVC pipe according to different properties. The main difference is whether it contains plasticizer. Soft PVC pipe contains water, so its physical properties are relatively weak and can not bear a certain water pressure. Therefore, soft PVC pipe is usually used in ceiling, floor and leather surface, and is often used as wire pipe. The hard PVC pipe does not contain plasticizer, so it is easy to form in production and has very good physical properties. Hard PVC pipe is usually used as drainage pipe and water supply pipe, which has great development and utilization value.
