UPVC And CPVC

Unveiling Striking Differences Between UPVC And CPVC

Table of Contents

Poly Vinyl Chloride (PVC) is regarded as one of the most widely used and produced synthetic polymers. Without an iota of doubt, it is one of the most known polymers as well. Its much-needed flexibility makes it easier to bend. In case you are wondering what gives such remarkable flexibility, let’s answer it for you. Plasticisers are added during the PVC manufacturing process which loads it with flexibility. In this article, let’s have a look at CPVC prices today, its features, and applications, and shed some light on UPVC features and applications as well.  

UPVC

There is another PVC manufacturing process where plasticisers are not added. Without such addition, the end product is UPVC (popularly known as Unplasticised Polyvinyl Chloride). Since it lacks the addition of plasticisers, it is very sturdy and rigid. All thanks to its never-ending resilience, UPVC is a tough and durable material. It displays praise-worthy resistance to atmospheric influences, different types of chemicals and moisture. Not just that, it has low flammability and is loaded with superb electrical properties.

When it comes to usage, UPVC fittings and pipes are used all over the world. Their inherent rigidity, durability, recyclability, fire resistance etc. makes it a reliable and trusted option for an array of applications.

UPVC Features

Mentioned below are the details:

  • High Performance: They undergo rigorous testing through multiple rounds of quality checks. This, in turn, makes them reliable and high-performing pipes.
  • Cost: They are cost-effective as well as low-maintenance.
  • Recyclability: UPVC pipes and fittings can be recycled multiple times without significant degradation in quality, contributing to the circular economy by reducing the consumption of raw materials and energy in the production process.
  • Durability: UPVC pipes and fittings are renowned for their exceptional durability. They have a lifespan of up to 50 years or more, making them a long-lasting solution for plumbing and industrial applications.

UPVC Application

These fittings and pipes are the perfect fit for employing in cold water applications across a variety of sectors, including (but not limited to) swimming pools, residential plumbing, the food and beverage sector, saltwater lines, the chemical sector, industrial process line etc.

CPVC

CPVC stands for Chlorinated Polyvinyl Chloride (CPVC). In a nutshell, it is a thermoplastic which is manufactured by PVC polymer’s chlorination. During the chlorination process, it develops certain excellent properties such as the tolerance to withstand harsh temperatures and flexibility. As compared to PVC, it is a stable material and can tolerate much higher temperatures.

It is widely used due to its chlorine content and it has excellent chemical resistance against alkalis, salts, and acids, making it a match made in heaven for the chemical processing industry. Over a period of time, these pipes not only can withstand chemical degradation but can also stand physical degradation which provides it a longer life. CPVC prices today start from 30/ metre.

CPVC Features

Mentioned below are the features:

  • Temperature Tolerance: It is a one-of-a-kind pipe system that can be used for cold water as well as hot water.
  • Approving Authorities: These pipes come with NSF (National Sanitation Foundation) and BIS (Bureau of Indian Standards), approval.
  • UV Stability: They have higher UV stability and can be used for external applications as well as internal applications.

CPVC Applications

CPVC finds diverse applications, including plumbing for hot and cold water distribution in residential, commercial, and industrial settings. It’s crucial in chemical processing due to its resistance to corrosive substances. CPVC is also used in fire sprinkler systems, HVAC, potable water systems, mining, agriculture, and recreational facilities.

Key Difference

Let’s have a look at the major differences between CPVC and UPVC.

  • Bendability: CPVC is bendable and used for applications that need flexible material. UPVC, on the other hand, is not at all bendable and is ideal for applications requiring a rigid material.
  • High-temperature: CPVC pipes can withstand high-temperature hot and cold temperatures and UPVC pipes can only withstand moderate temperatures.
  • Uses: CPVC is suitable for portable water-related uses and UPVC is suitable for industrial uses.

Over To You

A highly utilised product in pipeline production PVC comes in two types: UPVC and CPVC. The key differentiating factor is its composition and high-temperature resistance. 

Before chlorination, PVC has approximately 56%-57% of chlorine whereas after chlorination CPVC has approximately 63%-67% of chlorine in its hydrocarbon chain. With chlorination, the polymer gets a lot of stability and provides higher temperature stability. This also diminishes polymer oxidisation potential which is the major reason behind polymers degradation upon any exposure to UV radiation, oxygen or heat. Additionally, CPVC is devoid of lead and that makes it fit for potable water usage. As far as prices are concerned, Shandong Gaoxin CPVC K67 FOR -Saharanpur price today is ₹1,32,500/MT
