Formaldehyde Generation from Silicone Rubber
●The Occupational Safety and Health Administration (OSHA) defines formaldehyde as a hazardous chemical. It is characterized as a flammable, colorless gas with a pungent odor. Formaldehyde is considered and irritant, a sensitizer, and a potential carcinogen. Although silicone rubber generates formaldehyde through thermal oxidation, the rate at which it is produced is generally lower than that of many common materials. In aerobic atmospheres, silicone rubber begins generating formaldehyde at temperatures above 149oC. Additionally, materials that are manufactured from formaldehyde; materials that contain formaldehyde in their composition; and/or materials that produce formaldehyde as a by-product of thermal oxidation also generate formaldehyde. During thermal oxidation of silicone rubber, the rate at which formaldehyde is generated is dependent on temperature and atmosphere. To establish the required engineering controls, it is possible to estimate the rate of formaldehyde generation for a particular process with knowledge of a few essential variables.
