Chlorazone rubber

Chlorazone® rubber is Lavelle’s proprietary family of elastomeric formulations that is specifically designed to withstand chemicals found naturally in water or added to it by municipal treatment facilities. Introduced in 1990, it was the first chlorine-resistant material made available for plumbing applications. Chlorazone is a chemical-resistant rubber that is NSF/ANSI 61 certified, the toughest standard governing products coming into contact with potable water. It has been rigorously tested in water containing free chlorine and chloramines for over 25 years, making it an ideal choice for water-based applications.

 

Chlorazone is a chemical-resistant rubber that is:

  • Designed to resist potable water disinfectants (acids and alkalis) found in toilet bowl cleaners
  • Certifications include:

o   NSF/ANSI 61 – U.S and Canadian certification for Drinking Water

o   BS 6920 – British Certification for Drinking Water

o   NSF/ANSI 51 – U.S. and Canadian Certification for Food Equipment Materials

o   KTW – German Certification for Drinking Water

o   ACS – French Certification for Drinking Water

  • Available in a range of durometers from 35-90

 

Material performance results

To ensure Chlorazone is an effective chemical-resistant rubber, Lavelle has tested the material in extreme chlorine concentrations of 100 to 1,000 times greater than typical field conditions. During testing, we observed the following attributes:

  • Low volume swell
  • Low extractability
  • Low compression set
  • Low taste and odor
  • High tear strength
  • High and low pressure sealing ability

 

Chlorazone chemical-resistant rubber outperforms other materials such as SBR rubber and nitrile rubber.
