Smart rubber will recover its original mechanical strength within several hours of being split and then subsequently recombined. Residual hydrogen bond donors and acceptors responsible for the self-healing properties of the elastomer remain unpaired until the newly exposed surface comes in contact with another complementary surface, allowing formation of new intermolecular hydrogen bonds.
The two roll rubber mill is a machine used to process natural rubber into various compounds. Two horizontally opposed stainless steel rolls rotate in opposite directions towards each other at different speeds to mix the rubber and ingredients used to create the rubber compounds. Rubber being produced using a two roll rubber mill.
Although the most common types of self-healing materials are polymers or elastomers, self-healing covers all classes of materials, including metals, ceramics, and cementitious materials. Healing mechanisms vary from an instrinsic repair of the material to the addition of a repair agent contained in a microscopic vessel.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required.
Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
Self-healing hydrogels are a specialized type of polymer hydrogel.A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist [1] [2] and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
A clicking machine from 1922, used to die cut leather Schematic of the dinking process. Die cutting is the general process of using a die to shear webs of low-strength materials, such as rubber, fibre, foil, cloth, paper, corrugated fibreboard, chipboard, paperboard, plastics, pressure-sensitive adhesive tapes, foam, and sheet metal.
