Value chain management of natural rubber
A market leader in the value chain management of natural rubber is said to offer a plethora of grades from diverse originations to its customers globally, addressing their raw material needs in natural and synthetic rubbers, and creating value through its risk management solutions. The company is said to be positioned as a single-stop solution to the rubber industry's raw material requirements. The company deals in all kinds of natural and synthetic rubbers from global originations. The firm extends its professional risk management expertise through the value chain, thereby creating an unparalleled niche and value in tangible terms to both its suppliers and consumers. The company's mission is said to emphasize its core belief of service above anything else. This service oriented outlook not only extends to its customers, but also to all stakeholders in the business, encompassing small holder farmers, plantation owners, processors and facilitators throughout the value chain. Natural rubber, in its milky sap, is tapped from the Hevea brasiliensis tree. Most of the latex is either processed into sheets or solid crumb rubber. It can also be kept in its liquid form through the use of chemicals to prevent the latex from coagulation. In the solid form, the rubber sheets or crumbs are used in the manufacture of solid rubber based products, e.g., tires, etc., while the liquid form is used for dipping products such as gloves, balloons and condoms. Rubber grading under TSR (technically specified rubber) was established in the early 1970s. The rubber is graded by its dirt, ash, nitrogen content, volatile matter content and plasticity retention index. They have good processing characteristics and physical properties. Usually, such grades of rubber are high in green strength and tack, are easy to mix and have low viscosity. Common sources of TSR include Thailand, Indonesia, Malaysia, Vietnam, India, etc. However, quite recently the African and South American rubbers are said to be gaining popularity. Most Asian countries have a nomenclature of labeling their standard rubber with the country of their origin, such as Standard Malaysian Rubber as SMR, Standard Indonesia Rubber as SIR, Standard Thailand Rubber as STR, and Standard Vietnam Rubber as SVR. These are used in high performance passenger tires, motorcycle and bicycle tires, heavy load truck tires, conveyor belt, inner tubes and hose. Ribbed Smoked Sheets, or air dried sheets, are commonly known as RSS and can be graded.

Zero halogen, low smoke compound based on NR
Zero halogen, low smoke compound based on NR Natural-FR is a sustainable, zero halogen, low smoke, low toxic rubber compound based on natural rubber. Natural-FR has been developed based on a modified natural rubber grade that is renewable. It starts its journey from the latex of the natural rubber tree Hevea brasiliensis. Natural-FR can be used to meet material flammability criteria in industrial rubber products and has passed the flammability requirements for floor composites and flexible rubber-metal units as specified in the latest EU standard EN45545-2 (2013). Natural-FR in third party laboratory testing has passed such criteria as smoke density, heat release rate, ignitability, smoke toxicity, flame spread and dry and wet slip resistance for a flooring application, and is authorized for use in entrance matting in London Underground stations. Using Natural-FR, EMS developed two unique systems for the London Underground combining low smoke and toxic fume emission rubber with an excellent drainage facility incorporated into the debris channel system. Both systems are Section 12 approved. This matting system consists of a solid aluminum extrusion with a low smoke and toxic fume emission, heavily ribbed black rubber insert. Natural-FR can be molded using conventional rubber processing operations (compression, transfer, injection molding and extrusion). The use of Natural-FR with its ‘green credentials’ will assist industry to meet sustainability targets in products, according to the manufacturer. The rubber in Natural-FR is derived from renewable resources and a life cycle analysis has indicated the production of the polymer to have a significant negative carbon footprint.
