Rubber cement is simply a mixture of solid rubber in a volatile solvent that will dissolve it. When the cement is applied, the solvent evaporates, leaving the rubber as the adhesive. Almost any rubber (pre-vulcanized or not) can be used. [1] The rubbers used might be natural rubber, gum mastic or gum arabic.
There are many uses for vulcanized materials, some examples of which are rubber hoses, shoe soles, toys, erasers, hockey pucks, shock absorbers, conveyor belts, [6] vibration mounts/dampers, insulation materials, tires, and bowling balls. [7] Most rubber products are vulcanized as this greatly improves their lifespan, function, and strength.
Sulfur vulcanization is a chemical process crucial to the rubber industry, transforming raw rubber into a durable, elastic material. This process is suitable for a wide range of rubber products. On the other hand, peroxide vulcanization uses organic peroxides to form cross-links, resulting in rubber that withstands higher temperatures and ...
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. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins.
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.
The spin casting process typically uses vulcanized silicone or organic rubber as the mold-making substrate. Vulcanization is an integral step that occurs halfway through the mold-making process. Prior to vulcanization, the mold rubber is a soft and malleable solid-like fluid, in many ways very similar to Silly Putty. Because of the clay-like ...
RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.
Rubber Technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands. The materials includes latex , natural rubber , synthetic rubber and other polymeric materials, such as thermoplastic elastomers .
