Nitrosamine-free O-Ring

About this product

SAFE & STABLE Nitrosamine -FREE NBR O-Ring MF-N01 Certified by NSF/ANSI 42 Components

WORLD's FIRST First O-Ring to acquire NSF/ANSI 42 for the surface area to volume ratio of 8.2 inch²/L which is the largest in the world. Size Comparison: Microfilter's O-Ring 8.2 inch²/L · Other O-Ring 2.0 inch²/L Exceptionally substantial certified coverage

What is an N-nitrosamine? N-nitrosamines are organic compounds with the chemical structure R2N-N=O. There are more then 300 different N-nitrosamine impurities, all of which are categorized as carcinogens by IARC and ERP.

What causes N-nitrosamines in Rubber? The accelerator used during the rubber vulcanization could be broken down to secondary amine, which in turn could react with nitrogen oxide in the air to produce N-nitrosamine. Accelerators are categorized into Thiurams, Dithiocarbonates and Sulfonamides according to the chemical structure. 1) Vulcanization: The process of making polymer structure through heat treatment by combing sulfur, peroxide, and organic resin to strengthen elasticity of rubber.

Negative Effects of Nitrosamine Carcinogenicity : Tumors mostly found in internal organs such as liver, esophagus, and bladder Causes cancer through mutagenic mode of action (MOA) Formation of DNA adducts leads to errors in DNA replication, changes in cell proliferation, and ultimately the development of tumors Fetuses, newborns, and infants are more vulnerable to carcinogenic effects (EPA animal study showed that younger animals are more prone to developing liver tumor.)
