Runway rubber removal using pressurized water. Airfield rubber removal, also known as runway rubber removal, is the use of high pressure water, abrasives, chemicals and other mechanical means to remove the rubber from tires that builds up on airport runways.
Worker placing a tire in a mold before vulcanization. Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. [1] The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice.
Ebonite is a brand name for a material generically known as hard rubber or vulcanite, obtained via vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. [1] [2] Its name comes from its intended use as an artificial substitute for ebony wood.
Excessive crosslinking can convert the rubber into a hard and brittle substance (i.e. ebonite). Short crosslinks, possessing lower numbers of sulfur atoms, give the rubber better resistance to heat and weathering. Longer crosslinks, with higher numbers of sulfur atoms, give the rubber improved physical durability and tensile strength.
The length recovered after removing a load from a material just before it breaks is equal to the length recovered after removing a load just before it enters plastic deformation. The work-hardened steel bar has a large enough number of dislocations that the strain field interaction prevents all plastic deformation.

The major commercial source of natural rubber latex is the Amazonian rubber tree (Hevea brasiliensis), [1] a member of the spurge family, Euphorbiaceae.Once native to Brazil, the species is now pan-tropical.
Stain removal is the process of removing a mark or spot left by one substance on a specific surface like a fabric. A solvent or detergent is generally used to conduct stain removal and many of these are available over the counter.
