Rubber is bouncy sure but that s just the start of its numerous properties. The main chemical constituents of rubber are elastomers or elastic polymers large chainlike molecules that can be stretched to great lengths and yet recover their original shape the first common elastomer was polyisoprene from which natural rubber is made formed in a living organism natural rubber consists of solids suspended in a milky fluid called latex that circulates in the.
