EC rubber with conductive Vulcanite
EC rubber is the only static control rubber flooring that will never lose its ability to dissipate static electricity. The active static control ingredient in EC rubber is carbon, an intrinsic conductive element in the atomic table. All other static control rubber relies on liquid additives for static dissipative properties. Chemical additives lose effectiveness from the moment the flooring is washed for the first time, eventually losing all dissipative properties all together. Conversely, carbon remains conductive regardless of wear, time or maintenance as is not possible for an element to lose properties that are rooted in its base atomic structure.
EC rubber consists of two layers
- Top layer is composed of a matrix of covalently bonded carbon chips within an attractive surface design.
- Botom layer is a conductive rubber ground plane.
The top and bottom surfaces are inseperably fused by a process called vulcanization. This heavily cross-linked polymer has strong covalent bonds, with strong forces between the chains, and is therefore an insoluble and infusible, thermosetting polymer.
Vulcanization (or vulcanisation) refers to a specific curing process of rubber involving high heat and the addition of curatives. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon to carbon bonds. The end result is that the springy rubber molecules become cross-linked to a greater or lesser extent. This makes the bulk material harder, much more durable and also more resistant to chemical attack. It also makes the surface of the material smoother and prevents it from sticking to metal or plastic chemical catalysts.
The process is named after Vulcan, Roman god of fire. Vulcanization process is progressive reaction and therefore allowed for a specified time. A vast array of products are made with vulcanized rubber including ice hockey pucks, tires, shoe soles, hoses and many more.
