Frequently Asked Questions

What is difference between PVC and CPVC?

While both PVC and CPVC are derived from polyvinyl chloride, CPVC undergoes a process of chlorination that enhances its rigidity and ability to withstand higher temperatures. The introduction of chlorine in CPVC yields a more flexible material, offering improved insulation properties compared to PVC. This distinction allows CPVC to be a suitable choice for applications requiring elevated temperature resistance and enhanced flexibility, while PVC is commonly utilized for standard uses with lower temperature requirements.

What does CPVC stand for in pipes?

CPVC stands for chlorinated polyvinyl chloride. CPVC is a thermoplastic material that is similar to PVC but has enhanced properties, specifically greater resistance to heat and pressure. This makes CPVC suitable for use in various industrial applications that require a higher level of durability and performance.

Is CPVC stronger than PVC?

While both CPVC and PVC materials are strong in their own right, it is important to consider their unique properties. CPVC is known for being harder than PVC, but this hardness comes at a cost. While CPVC is more prone to breaking and can be easily warped or cracked, it does offer greater flexibility compared to PVC. Consequently, when utilizing longer lengths of CPVC, it becomes imperative to incorporate additional support every three feet to prevent any potential issues. Ultimately, the strength of CPVC is influenced by a careful balance between its hardness and flexibility.

What does CPVC stand for in plastic?

CPVC stands for chlorinated polyvinyl chloride. It is a thermoplastic that is created by chlorinating polyvinyl chloride (PVC) resin. CPVC is known for its high flexibility and ability to withstand higher temperatures compared to PVC. It is commonly used in various applications including hot and cold water delivery pipes as well as industrial liquid handling.
