Product Details

SVR 10

Materials used to produce rubber is auxiliary latex (coagulum latex, bowl latex, braid latex). These latexes are mixed with one another according to a appropriate proportion to create quality products. Specifications of this rubber include Po index, impurities content, plasticity retention index, ash content, volatile matter content, nitrogen content. Difference among materials used to manufacture this rubber require a closer control quality of grades from the latices (SVRL, CV) and a more meticulous blend. Producing block rubber from auxiliary latices must be done through a lot of steps: preliminary cleaning of materials, cutting into small pieces, chopping into smaller pieces (reducing size), drying…

PROCESSING:

Application:

This is a type of rubber produced from coagulum latex, miscellaneous latex and through a skilful process, so the rubber is tough. Therefore, this rubber is mixed with low-grade RSS, CV50 to manufacture very good products.
In addition, it’s possible to combine this rubber with grades of latex to create GP (general purpose) products in order to meet basic requirements of tyre production.
