Standard Indonesian rubber

This is the generic name for the scheme originally introduced in Malaysia as Standard Malaysian Rubber (SMR). In effect it is the same specification but apphed to rubber produced in other countries, e g., Standard Indonesian Rubber (SIR). Both SMR and SIR are Technically Specified Rubbers. [Pg.64]

NR suffers from inconsistent properties. Multiple stages of handling and transportation, and proeesses, are subject to contamination of NR latex (Figure 1.5). The grading of NR was correlated with a visual inspection of its dirt content in early years. Uniformity and purity of NR latex and dry NR as the commodity materials are overcome by introduction and enforcement of conformity of NR to strict technical specifications, e.g. Standard Malaysian Rubber (SMR, introduced in 1965 and revised in 1973 and 1991), Standard Thailand Rubber (STR), Standard Indonesian Rubber (SIR) and Standard Vietnam Rubber (SVR). Under SMR, tolerable amounts of nitrogen, dirt, volatile matter, copper and manganese are specified. STR, SIR and SVR are prepared based on SMR. [Pg.34]

After World War II, rubber growers conducted surveys of customers to find out how their product could compete most effectively with the synthetic rubbers then available. As a result of these surveys, rubber producers developed technically specified rubbers. First introduced by Malaysia about 1965 as SMRs (Standard Malaysian Rubbers), they were accepted so well that other countries followed with similar products such as SIR (Standard Indonesian Rubber) and TTR (Thai Tested Rubber). [Pg.1036]

NR was Standard Indonesian Rubber (SIR-10), carbon black was NllO (Cabot) and silica was Ultrasil VN3 Sp (Degussa). The coupling agent was bis-(3[triethoxysilyl]-propyl)-tetrasulphane (TESPT) (Si 69, Degussa) [9]. The compound formulation is given in Table 12.1 and the composition of fillers is given in Table 12.2. [Pg.341]

Malaysian and Indonesian natural rubber growers have established a system based on technical characteristics. A summary of the standard technical specification scheme shown in Table 4 for natural rubber can be foimd in ISO 2000 (14,15). In addition to the solid form of natural rubber, it is available as a suspension in water and is known as latex. Synthetic rubbers are also available in latex form. Latex has become an important commodity used in the manufacture of dipped goods for pharmaceutical applications. The principal uses of natural rubber are as follows tires and tire retreading, 70% latex (eg, gloves), 12% mechanical goods, 9% load-bearing components, 4% and other, 5%. [Pg.7284]
