When rubber is exposed to acetone, several chemical reactions can occur. Acetone can act as a solvent for many types of rubber, leading to significant changes in the rubber's physical and mechanical properties. For instance, natural rubber, which is primarily composed of polyisoprene, can swell significantly when dipped or soaked in acetone. This phenomenon occurs because acetone molecules penetrate the rubber matrix, disrupting the intermolecular forces within the rubber. As a result, the rubber may lose some of its structural integrity, leading to deformation or even permanent damage.

Another critical application of aluminum hydroxide in veterinary medicine is as an adjuvant in vaccines. Adjuvants are substances that enhance the body's immune response to an antigen, and aluminum hydroxide has been widely used for this purpose in both human and veterinary vaccines. By creating a depot effect, where the antigen is released slowly over time, aluminum hydroxide prolongs the immune response, leading to a heightened and more durable immunity against diseases.
