PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds, soft PVC 1/3. Soft PVC are generally used for surface floors, ceilings and leather, but because of soft PVC containing plasticizer (which is soft PVC and rigid PVC distinction) pvc pipe fittings, poor physical performance (as pvc pipes need to withstand a certain pressure pipes, soft PVC is not suitable for use), so its use has been limited. Hard PVC plasticizer-free, so easy molding, good physical properties, and therefore has great development and application value. PVC material production process, is bound to add some additives, such as stabilizers, plasticizers, and so, if all the use of environmentally friendly additives price pvc pipe, PVC pipe that is also non-toxic and tasteless green products. PVC qualities as a slightly yellow translucent and shiny. Transparency than polyethylene pvc pipe manufacturer, poly-ene this good, but slightly worse than polystyrene. PVC pipe is divided into rigid PVC hose and PVC pipe, PVC rigid pipe has good tensile, flexural, compressive strength and impact resistance, can be used alone as a structural material. PVC hose flexibility, elongation, cold resistance will increase, but the brittleness, hardness, tensile strength will be reduced. PVC is often used to make toys, stationery, doors and windows, plates, etc., it is a polymer material.
