Live Better

Protecting Life

Lubrizol products, solutions and people strive to protect and improve lives around the world by ensuring our products are safe for their intended use and help people to live better.

Lubrizol CPVC Compounds conform to industry standards and carry regulatory approvals and third-party certifications.

Lubrizol has spent considerable amount of resources and worked closely with various international and local agencies to ensure that stringent standards are met to ensure the materials are safe and do not pose any health hazard.

Lubrizol over the many decades of existence has made an organization with high moral standards for its employees. Health, safety, and the well-being of employees comes first. Ethical working is the foundation along with building blocks of diversity and inclusion.

Lubrizol relentlessly works to train its employees to have the highest standards of ethics, open mindedness, transparency, empathy for others and actively undertakes various activities for their communities.

Lubrizol has worked closely with its customers and continuously works in helping them train their teams in various aspects which has resulted in better performance and meaningful growth of our customers.

Lubrizol's Research and Development team over the past decades has worked relentlessly to ensure that the products and solutions being offered are tested, tried and certified for use.

Lubrizol CPVC -- A durable and safe material

The combination of properties of TempRite® CPVC is the reason it is often selected for long service-life applications. These properties include:

Resistance to corrosion and chemical attack. CPVC often replaces metals to provide longer service-life in handling corrosive materials such as aggressive water, mineral acids, caustics, and other solutions. As a result, Corzan® CPVC Industrial Systems improve the safety and performance of many industrial applications.

High purity. Lubrizol CPVC (including FlowGuard®, BlazeMaster®, and Corzan® CPVC) is approved for potable water applications worldwide by several organizations.

Potable Water Approvals

USA: NSF International

Germany: Deutscher Verein des Gas-und Wasserfaches (DVGW)

UK: Water Research Council (WRC)

Canada: Canadian Standards Association (CSA)

Holland: Keuringsinstituut voor Waterleidingartikelen (KIWA)

These approvals are based on extraction studies which have verified that ingredients do not migrate from CPVC at levels that would be considered unsafe by local standards.

Bacterial growth in water handling systems

Bacteria are encountered in nearly all situations where there is exposure to the natural environment or where water is handled. Products manufactured from TempRite CPVC have extremely smooth surfaces and thus provide few places for bacteria to attach and multiply. Several studies of piping materials in water service have shown that CPVC supports the lowest bacterial growth of all the materials tested including steel, copper and polyethylene.

In one comparison with CPVC, bacterial growth buildup was twice as heavy with stainless steel, six times as heavy with copper, and 45 times as heavy with polyethylene.

Bacterial Growth in Water Piping

Biofilm formation potential study conducted by KIWA on different piping materials showed that Biofilm formation was the lowest on CPVC.

Study on Water deterioration from stagnated extended stagnated conditions showed the CPVC was the clear winner by having least deterioration

Study on Biomass Production potential of various piping materials at 30°C  & 50°C showed that CPVC supported the least Biomass production

Another study with CPVC piping showed 20 times as much bacterial with copper and 30 times more with carbon steel.

Protecting Human Health

Multiple studies have been done by 3rd parties to demonstrate that CPVC safe for human health. Some of those studies are cited below: (Additional information is available upon request)
