Another definition of foam is a bubbly liquid, particularly if the bubbles, or froth, are undesirable..
Is foam a type of rubber?

Is foam rubber waterproof?
A waterproof, light and flexible type of foam rubber. … Foam rubber, on the other hand, is already a well-known phenomenon. For example, it is widely used in the packaging industry. The material is therefore widely applicable and has a number of fine properties.
