PVC hose is a type of industrial hose. It uses PVC as the main material, and then adds certain auxiliary materials to meet certain usage requirements. The so-called PVC material is actually a general-purpose synthetic resin with the chemical composition of polyvinyl chloride, and it can be seen everywhere in our daily life. For example, it is widely used in electronics, and after baking the PVC hose, it can Wrapping on the wire acts as insulation.
Things to note about PVC hoses:
1. Barrier properties of materials.
If the packaged product is highly volatile content such as essential oils, we must choose a five-layer co-extruded tube with an oxygen transmission rate of 0.2~1.2 units. Because this kind of hose has better barrier properties than ordinary ones.
2. Stiffness of material.
Generally speaking, different enterprise packaging products will have different stiffness requirements for PVC hose materials. Usually, high-density polyethylene is better than low-density polyethylene, and the required stiffness can be achieved early by adjusting the ratio.
3. Selection of pipe materials.
First of all, the materials used in PVC hoses must comply with relevant national health standards, and some harmful substances such as heavy metals must also be controlled within a reasonable range in accordance with regulations.
4. Chemical resistance and weather resistance of materials.
When PVC hoses have similar stiffness, high-density ones have better chemical resistance than low-density ones. Weather resistance depends on the choice of varnish type and color masterbatch type.
PVC hoses are also widely used in construction. For example, after being heated at high temperatures, they can be shaped into different types of casings, which can be used to protect electrical appliances and many circuits.
