Introduction And Application of CPVC Plastic

CPVC has a very high heat resistance, the highest service temperature can reach 93°C-100°C (110°C in short term), and the heat resistance is much higher than that of PVC. This is the most fundamental difference between CPVC and PVC. CPVC also has excellent chemical resistance, and has strong tolerance to acid, alkali, salt, oxidant and halogen. Can withstand a wide range of industrial chemicals, including many highly corrosive media (such as concentrated hydrochloric acid, dilute sulfuric acid, etc.). CPVC is anti-flaming, low smoke density, self-extinguishing from fire, and low smoke density when burning. 

This feature makes it popular in places with strict fire protection requirements (such as hotels, hospitals and subways). It can still maintain high strength and modulus at high temperature. 

The application of CPVC is almost completely concentrated in the industrial and civil fields with strict requirements on heat resistance, corrosion resistance and flame retardant. Industrial pipeline system is its biggest application market. 

Chemical industry: process pipeline, waste water treatment pipeline, electroplating solution transportation pipeline, chlor-alkali industry. Smelting and electric power: wet smelting pipeline, chemical pipeline in power plant, desulfurization system. Semiconductor and electroplating: high-purity water transportation, acid-base waste liquid discharge. Papermaking and Textile: Bleach and Chemical Transportation. Civil building piping system: fire sprinkler system (core application). 

This is the landmark application of CPVC in the world. Because of its characteristics of flame retardancy, corrosion resistance, no rust, light weight and quick installation, it has gradually replaced galvanized steel pipes and become the first choice for automatic sprinkler systems in civil buildings (hotels, hospitals, office buildings, houses and schools).
