Triacetin, also known as glycerol triacetate, is a synthetic liquid organic compound used in a variety of industries. It is commonly used as a plasticizer in plastics, as a solvent in ink and paint, and as a food additive.
When rubber is exposed to triacetin, it can cause the rubber to become brittle, swell, and eventually crack. The plasticizer may leech out of the rubber, reducing its strength and durability. If the rubber is in direct contact with triacetin, it may cause accelerated degradation and cause the rubber to become hard and brittle. It is important to choose the right type of rubber to ensure it is able to withstand the environment it is exposed to.
