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.
