Rubber statistics
Rubber statistics The 2014 edition of Worldwide Rubber Statistics is said to be the world's leading source for authoritative data about synthetic rubber. This edition of the book, which has been published annually for more than 30 years, has revisions to other elastomer type capacities as the synthetic rubber market continues to be dynamic. In addition, intelligence on the Chinese market has been enhanced. The 86-page book is said to provide a comprehensive analysis of capacity by elastomer type, by geographical distribution and by corporate ownership. It also features a graphics section that emphasizes statistics in an easy-to-read format, and a section on capacities of synthetic rubber production facilities throughout the world, including a section on planned and announced expansions of synthetic rubber plants.

Conductive adhesive
A thermally conductive adhesive has been developed for electronics applications. Semicosil 975 TC silicone rubber is characterized by high thermal conductivity and good flow and processing properties. Even light pressure is enough to form an ultrathin adhesive layer between the contact surfaces. Semicosil 975 TC is an addition-curing silicone rubber that cures at temperatures above 90C.

Coagent additives
Natrochem and Arkema's Sartomer Division have partnered with this company which provides additives that can help enhance physical properties of peroxide-cured elastomer compounds. Natrochem works closely with the Sartomer team which provides liquid coagents to create the Natrochem Dry Liquid Concentrates (DLC) of those liquid coagents. Use of peroxides has been proven to enhance heat aging performance, but by themselves fail to maintain the dynamic properties of a sulfur-cured compound. However, with the addition of coagents to peroxide curing, it has been demonstrated in numerous applications that dynamic properties such as compression set, hardness, modulus, elongation and tensile strength can be maintained or improved beyond sulfur vulcanization. Moreover, coagent addition to a peroxide cured elastomer is said to improve the rate of cure, the state of cure, and heat and chemical resistance. Additionally, coagent addition can potentially reduce the peroxide initiator requirement. Coagents that increase both the rate and state of cure are referred to as Type I. The second class of coagents, referred to as Type II, typically generates fewer reactive radicals through hydrogen abstraction contributing only to the state of cure. Sartomer recently introduced a new liquid coagent, SR 523, which has both methacrylate and allyl functionality.

Platen insulation
Pyropel platen insulation is said to have improved part quality for an automative seal manufacturer. The brake seal molding facility was having difficulty maintaining tight product tolerances because of the failing glass reinforced polyester platen insulation. The boards were degrading and losing parallelism, and the molds were not closing properly. The problem was so significant, it required the insulation boards to be replaced every six to eight weeks. Following the company's continuous improvement program, engineering was focused on finding a solution to improve product quality and consistency. The firm evaluated Pyropel MD-60, a thermal/mechanical platen insulator designed to improve molding performance. Pyropel MD-60 platen insulation was easily able to withstand the operating conditions and helped the rubber molder to maintain high repeatability in product quality.

Russian dandelion lines used for latex extraction
Russian dandelion lines used for latex extraction A U.S. biotech company and this international molecular genetics company specializing in agricultural biotechnology have developed the first Russian dandelion lines that can be tested and used for latex extraction. Following a rigorous breeding strategy leveraging its molecular and DNA tools, the company is said to have produced improved Russian dandelion lines with superior agronomic performance, latex quality and yields. The two firms recently entered into collaboration developing, breeding and testing Russian dandelion for the production of natural rubber. In parallel to this program, the company has also cross-bred Russian dandelion and European common dandelion plants, resulting in new breeding material with heavily increased vigor and tap root size. The inter-specific dandelion lines are now being tested for latex and rubber yields and quality. These tests will provide suitable material to launch further breeding, seed production and, ultimately, cultivation for latex and rubber production. Quality seeds from these superior lines have been produced, processed and delivered to the biotech company, which will develop production practices and latex extraction procedures to establish Russian dandelion rubber production in North America. These dandelion innovations will significantly contribute to solving the worldwide need for increased natural rubber production and diversification that have until now been solely derived from one species, the Hevea tree, which grows in only a few major production areas, according to the company. The firm is said to deliver sustainable responses to the world's needs for yield stability and quality of vegetables and field crops. It supports its strategic partners with cutting edge breeding technologies and plant-based trait platforms to meet their needs. ()
