How to distinguish between PVC and PPR ball valves

As a new type of water pipe material, PPR pipe has unique advantages. It can be used as both a cold pipe and a hot water pipe. Because of its non-toxicity, light weight, pressure resistance and corrosion resistance, it is becoming a popular s material. Also suitable for hot water pipes and even pure drinking water pipes. The interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together, so once the installation and pressure test is passed, there will be no aging and water leakage for a long time, and the PPR pipe will not be scaled. PVC material is a kind of plastic decorative material. PVC is the abbreviation of polyethylene material. It is a material made of polyethylene resin as the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc., through mixing, calendering, vacuum forming and other processes. PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardant, easy construction and so on. There are many specifications, colors and patterns, and it is very decorative. It can be used in the decoration of indoor walls and ceilings. It is one of the most widely used decorative materials in plastic materials.
