What is rubber?
The first rubber material used for every sort of rubber product was natural rubber. Natural rubber comes from the rubber trees in South America and Asia. Years ago, natural rubber was used to make tires and weatherstripping. The first rubber tires were actually white, but researchers added carbon black to make tires stronger. Today's automotive rubber is usually made from a synthetic formulation known as EPDM.
METRO rubber is made from an advanced, propriety EPDM formula which has superior ozone and UV resistance. METRO's rubber products are also molded using high heat and 40-to-125 tons of pressure, which gives them a longer life and clean, smooth looks.
