UV Resistant Rubber Sheet Products for Outdoor Industrial and Flooring Usage

For outdoor flooring applications, materials containing EPDM are the most suitable.  Since EPDM is ozone and UV stable, matting containing this material will exhibit a significantly longer life span when used outdoors.  However, since pure EPDM is one of the more expensive sheet rubbers (due to the specific technical characteristics of this material), pure EPDM is too costly to use as a flooring or matting product (Elephant Bark Rubber Flooring, Playground Surfacing).  Therefore, products containing a high percentage of EPDM provide a more cost effective alternative, while still preserving the essential outdoor-friendly characteristics.  One of the benefits of recycled tire products for outdoor applications is that car tires (which are designed for constant exposure to the elements) contain a hefty amount of EPDM.  For flooring designed for outdoor applications, the EPDM content of the recycled material is augmented by either blending colored EPDM speckles into the raw material or by coating the exposed surfaces with similar EPDM speckles.  This makes recycled mats ideal for outdoor applications.

Why is EPDM the UV resistant Rubber Sheet for Outdoor Use?

For any sort of gaskets or seals or even for an outdoor mat or flooring that will be exposed to the elements, a material containing EPDM is generally the best option.  EPDM provides excellent UV and Ozone protection, making it the preferable elastomer for outdoor use, because it will outlast most other rubber elastomers.  Due to high production costs/technical characteristics of this material however, EPDM is generally blended with other rubbers, which allows for it to exhibit the same characteristics while being more cost effective.  For this reason, there are very few rubber sheeting or mats that would have 100% EPDM content.   Since tires contain large amounts of EPDM, recycled products such as Elephant Bark, Puzzle Lock and Playground tiles have excellent UV and Ozone resistances, making them ideal for not only indoor, but outdoor mats and flooring too.  When looking for outdoor mats or an outdoor flooring product, finding out the EPDM content would be beneficial.  If the product is made from recycled tires, it will certain have a high content of EPDM, and provide an eco-conscious surfacing as well.
