CPVC is a material that maintains the excellent properties of PVC, but by adding chlorine, it can be used under harsh conditions that conventional PVC cannot handle. We will explain what characteristics CPVC has.<\/p>\n\n\n

Overview of CPVC(chlorinated polyvinyl chloride)<\/span><\/h2>\r\n\n\n\n

CPVC (chlorinated polyvinyl chloride resin) is a plastic produced by post-chlorination of PVC (polyvinyl chloride resin), which not only further improves the flame resistance of PVC, but also provides high chemical and heat resistance. <\/p>\n\n\n\n

It is therefore used in applications such as hot\/cold water supply pipes and fittings, fire sprinkler pipes and fittings,industrial pipes and fittings.<\/p>\n\n\n\n

\n

What is CPVC?<\/h3>\n\n\n

CPVC is an abbreviation for chlorinated polyvinyl chloride, sometimes referred to as \u201cC-PVC\u201d or \u201cchlorinated PVC\u201d.<\/p>\n\n\n

What is CPVC Resin?<\/h3>\n\n\n

Generally, it refers to CPVC raw material resin that has not been mixed with any additives.<\/p>\n\n\n\n

What is CPVC Compound?<\/h3>\n\n\n

CPVC compound are CPVC resin that have been blended with additives and stabilizers and processed to make them suitable for molding into a variety of products.
It is supplied in powder or pellet form according to the molding method.<\/p>\n\n\n\n

Strengths of CPVC(chlorinated polyvinyl chloride)<\/span><\/h2>\r\n\n\n\n

CPVC has excellent properties, specifically heat resistance, flame resistance and chemical resistance.<\/p>\n\n\n\n

\n

Heat Resistance<\/h3>\n\n\n

The Vicat Softening Temperature of CPVC is 10 – 40\u00b0C higher than that of conventional PVC. <\/p>\n\n\n\n

It can be used in applications where it is regularly exposed to high temperatures, where general PVC cannot be used due to softening. Suitable for applications such as hot\/cold water supply pipes and fittings.<\/p>\n\n\n\n

Flame Resistance<\/h3>\n\n\n

CPVC has self-extinguishing and produces little smoke when exposed to flame, making it suitable for fire sprinkler pipes and fittings.<\/p>\n\n\n\n

Chemical Resistance<\/h3>\n\n\n

CPVC has excellent resistance to strong acidic and alkaline conditions and retains its properties even at high temperatures.<\/p>\n\n\n\n

Other Strengths<\/h3>\n\n\n

In addition, CPVC has excellent bending resistance, flexural modulus and tensile strength, and can be used in environments where metals are prone to corrosion. It also has better insulation properties than copper pipes.<\/p>\n\n\n\n
