Title Formaldehyde levels based on bulk and elevated temperature evolution rate measurements of silicone materials
Bibliographic information Dec. 1995, Vol.56, No.12, p.1201-1207. Illus. 14 ref.
Abstract A method was devised to measure the evolution of formaldehyde from certain silicone materials at high temperatures. The method involves the use of a modified thermogravimetric analyzer in conjunction with a hydrazine-polarographic electrochemical test. The method is specific to formaldehyde and there is no interference from other aldehydes. Elevated temperature formaldehyde evolution rate data and their possible impact on the workplace exposure level are presented for several silicone materials. The data suggest that substances such as lubricating oils, gaskets, etc., generally considered to be innocuous, may also be sources of formaldehyde at high temperatures.
