x86 Posted July 3, 2015 Report Share Posted July 3, 2015 Does anyone know how bleach will affect silicone? There are conflicting chemical resistance charts online - what would be a suitable substitute for flexible tubing (to run through a peristaltic pump) - if silicone is severely affected by bleach?

chem geek Posted July 5, 2015 Report Share Posted July 5, 2015 According to this link and this link and this link, silicone is Good for sodium hypochlorite (not for chlorine, but that's chlorine gas which is very acidic as opposed to sodium hypochlorite which is alkaline).

x86 Posted July 6, 2015 Author Report Share Posted July 6, 2015 Still not convinced from these and other (more critical) tables that silicone is a suitable material. Looks like Viton is a better option and looks to be easy to source. Quote Link to comment Share on other sites More sharing options...
