White rubber is a form of ethylene propylene diene monomer (EPDM), often manufactured in sheets and sold in rolls. It is resistant to punctures and can stand moderate foot traffic. Because of its durability and ease of installation, white rubber sheeting is often used for building applications such as roofing.
One trait of white rubber that makes it suitable for many building applications is its flexibility, which allows it to conform to minor irregularities in the underlying surface without cracking. This makes it perfect for waterproofing, even in older structures where the subsurface may be uneven.
EPDM is non-toxic and has been approved by the FDA for use in contact with food products. This, combined with the fact that it repels grease, makes it ideal for many food service applications. Countertops, gaskets and skirting in areas where food is prepared are often made of white rubber.
White rubber is chemically inert and can be used for biological facilities, pharmaceutical manufacturing applications, cosmetic storage and grocery stores. White rubber sheeting can be used in all home applications, including those where children are exposed to it, without fear of adverse effects.
