1-5/16" VULCANIZED MAT™
"Vulcanization" is a special chemical process invented by Charles Goodyear. It stabilizes the elastic properties of rubber, effectively making the mat into a "single, huge molecule". Vulcanized rubber has a stable shape which cannot be reversed. It can take repeated loads and return to its original shape.
Most other mats use a "bound rubber" process, which combines recycled tire rubber with various adhesives ... under pressure. Variations in the adhesive formula can dramatically affect a mat's ability to resist long-term exposure from load pressure, moisture and chemicals.
Vulcanization = "single-molecule type construction." Vulcanized mats retain their "elastic memory." While all mats will stretch under load pressure, vulcanized mats will spring back to their original shape. Even after years of use, their softness and shape will remain the same.
Single-molecule type construction = "single piece of rubber." Vulcanized mats feature excellent flexibility, and can be handled and stacked without damage. They won't crumble nor deteriorate from daily exposure to load pressure, moisture, chemicals, sun, or hot/cold extremes (see longer warranty).
Elastic memory = "self healing." Sharp cuts will bounce back, becoming almost invisible. If an oversize hole is drilled for installation, the surrounding vulcanized rubber will grip the fastener, creating a seal.
Nonabsorbent = no place for germs, moisture or dirt to hide. Vulcanized mats clean more thoroughly ... due to the non-porous surface.
"Vulcanization" is more expensive than a "bound-rubber" process. However, vulcanized mats will remain softer, are self-healing, and are more durable.
