You’ve most certainly heard of PVC – most typically used in pipes. CPVC is similar and shares many of the same properties, with some differences, and has many positive properties.
CPVC stands for Chlorinated Polyvinyl Chloride, and is a thermoplastic produced by the chlorination of Polyvinyl Chloride (PVC) resin. The major difference between PVC and CPVC is that due to its extra chlorine atom, CPVC is more chemically resistant and can withstand a higher range of temperatures. And for that reason, many building codes require the use of CPVC as opposed to PVC for use in hot water applications. For example, the ASTM standard allows PVC to be used in applications up to 140 degrees F., whereas CPVC can handle temperatures up to 200 degrees F.
CPVC performs especially well in acids and bases, but poorly in some organic solvents like MEK.
What are the highlights of CPVC fasteners
CPVC is more suitable for hot water applications. CPVC has become widely used for both hot and cold potable water.
As compared to PVC which is used primarily within residential applications, cold water systems, vent systems, and drainage systems, the more resistant properties of CPVC make it useful for tougher commercial and industrial applications.
CPVC is usually pricier than PVC, but it is still a very cost-effective and versatile material, especially compared with other acid-resistant polymers like fluoroplastics.
CPVC is recommended for applications where the maximum temperature can exceed 180 degrees Fahrenheit and maximize at 200 degrees Fahrenheit.
CPVC is easily machined, molded, formed, or welded.
It is inherently flame retardant, with a UL rating of V-O.
CPVC is significantly more ductile than PVC, allowing greater flexure and crush resistance.
The mechanical strength of CPVC makes it a viable choice to replace many types of metal – in conditions where metal’s susceptibility to corrosion limits its use.
CPVC is similar to PVC in fire resistance – it is difficult to ignite and tends to self-extinguish when not subjected to a directly applied flame.
In which applications can you use CPVC within Plastic Fasteners?
What industries use plastic Fasteners made with CPVC?
Plastic fasteners manufactured with CPVC are used in industries such as: Semiconductor Manufacturing, Chemical Processing, Waste Water Treatment, and a myriad of residential, commercial, and industrial applications.
When choosing components and fasteners for manufacturing and production, it’s important to consider the application, the environment of the finished products and the characteristics of the materials available. Plastics, and especially some of the advanced composite materials, make a great choice for many applications and offer exceptional strength and resistance to wear.
CPVC is a choice within a wide variety of plastic fasteners, but it’s not used in every application. If you have any questions on the properties of nylon plastic fasteners, or its use within your application, please do not hesitate to contact us. We’re here to help!
