UPVC:

Unplasticized polyvinyl chloride is a solid, versatile material that is resistant to a large number of chemicals. UPVC is a tough, sinewy, transparent and hard-wearing material, but it is very resistant to the influence of the atmosphere, moisture and chemicals, has excellent electrical properties and low flammability. Tubes and fittings made of UPVC are suitable for installation in and out of the soil. This material is resistant to aggressive environments – caused by natural phenomena or industrial outbreaks. It is also resistant to all kinds of corrosion. The advantage of tubes and fittings made of UPVC is the long life, resulting in a long period of safe installation. UPVC has excellent chemical resistance, which eliminates the formation of limescale and provides good flow characteristics. UPVC is odorless and tasteless, it is suitable for transport of processed water, wastewater, as well as for a large number of chemicals. UPVC is suitable for use at temperatures ranging from 0°C to 65°C at a wide range of operating pressures, depending on the selected system. It is also easy and simple to install – using a bundle for joints and not requiring special tools.

 

CPVC:

Chlorinated polyvinyl chloride (PVC) is a thermoplastic made by chlorinating the polyvinyl chloride resin. It is resistant to degradation and provides a long life span of use. In fact, the first pipeline systems used by the CPVC Pipe occurred in 1959, and they continue to work without any problems. CPVC is additionally chlorinated PVC. The chlorine bonded to the carbon atoms of the pre-chlorinated PVC contains 65-67% chlorine, which is 7% more than UPVC. Because of the increased chlorine content, it has excellent chemical resistance, primarily to acids, alkalis and salts, and is therefore very suitable as a material in the chemical process industry. The temperature range of application ranges from -40°C to + 95°C. CPVC is an extremely valuable, structurally rigid and solid plastic material used in industrial media transport applications with a maximum operating temperature of up to 100°C. Like other PVC systems, it is characterized by easy handling and simple and fast bonding. It also optimal fore transfer of treated and untreated drinking water, demineralized water and water for spa and medical use. Another advantage is the high value of perimeter strength, which ensures extended life of the device without significant mechanical or physical damage. CPVC is characterized by its optimum temperature stability, and its non-flammability which is an important factor in its use. Thanks to its long life in aggressive and corrosive environments, CPVC is becoming more and more important.
