Inquiry (采购产品): deterioration Hoping you can help me. I have begun to notice that rubber items such as gaskets or o-rings quickly deteriorate in my home--in about six months time. I am concerned that the cause of this deterioration might also be hazardous to my health.....are there gases that might be present in household air that would deteriorate rubber items? I would appreciate your suggesting a source for this information if you are unable to help. I found your site through a search of the web. Thank you.
