Q: What is the shelf life of a silicone product?

A: The effective shelf life of silicone rubber compounds is dependent largely on what is required from the compound in processing terms. The material tends to stiffen with age but this can be overcome by freshening on a two-roll mill. In general terms, most compounds have a declared shelf life of at least 6 months.

Q: Is silicone toxic?

A: Silicone is considered to be a very safe polymer with virtually no toxic effects in most environments. Also, as silicone is not considered as hazardous waste it can be disposed of in accordance with the local regulations regarding waste disposal.
