Semi-organic polymer, man-made material known for wide-ranging stability and water repellence.
Silicone has a tight molecular structure and retains heat. Try to soak silicone toy (make sure it's waterproof) in the warm water before using it to get nice warm feeling. Silicone also repels dirt and bacteria and doesn't fall apart with extended friction.
Hygiene And Maintenance
Silicone is smooth and not porous. Silicone can be fully disinfected by boiling it for 3 minutes or by throwing it into the top rack of your dishwasher.
