Y. Ikeda, in Chemistry, Manufacture and Applications of Natural Rubber, Introduction: The importance of sulfur cross-linking of rubber. Vulcanization is a cross-linking reaction by sulfur that generates three-dimensional network structures in rubber and is the best-known process of giving rubber products greater stability. Vulcanization was discovered by Goodyear in before the. Natural rubber comes from the Havea brasiliensis tree, which grows in tropical regions. They typically reach metres in height on rubber plantations, and are able to produce commercial quantities of latex at about 7 years of age, depending on climate and location.

Alternative curing techniques (e.g. peroxide induced vulcanization and e-beam curing) are displaying other disadvantages such as high production costs and operational safety concerns. The present work deals with a new pre-vulcanization process for natural rubber latex which is based upon an UV induced pre-curing of the latex emulsion. It is a form of latex ideal for small scale manufacturers of balloons and gloves where it does not require to compound the latex to produce superior products. This will bring down the cost of production of small scale units. It has long shelf storage life, online process life, consistency and stability. Natural Rubber Latex. Not only is Kent Elastomer Products proud to be one of the few companies in our industry that can claim that all our products are still made in the U.S.A., we’re the ONLY company to domestically manufacture our natural rubber latex tubing. This means shorter lead times, higher quality, and more responsive customer service.

Peroxide crosslinking of diene elastomers From an analysis of the stoichiometry of peroxide crosslinking for natural rubber using di-t -butyl peroxide and dicumyi peroxide, it has been concluded that these peroxides form one mole of crosslinks per mole of peroxide, i.e. they are quantitative crosslinking by: (2) The term “dry natural rubber” means rubber that is produced by the dry natural rubber process that involves the use of coagulated natural latex in the form of dried or milled sheets. Products are formed from dry natural rubber by compression molding, extrusion, or by converting the sheets into a . A latex allergy is an allergy to products made from natural rubber latex. The allergy-causing particles become attached to the cornstarch powder in gloves, swimming caps and balloons. Moisture from the skin can enhance this process. The particles can become airborne and inhaled when products are used.
