My uncle said that fears of outgassing are often exaggerated, but a way to double-check on any particular material is to look up its MSDS Sheet (Material Safety Data Sheet):

http://www.msds.com/

A Material Safety Data Sheet (MSDS) (also known as PSDS (Product safety data sheet) or a COSHH data sheet in the United Kingdom) is a form with data regarding the properties of a particular substance.

An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. MSDS formats can vary from source to source within a country depending on national requirements.

I'm sure that the perfect material is out there and you will find it. Good luck with your research!
