SKIM BLOCK
This is a by-product of the Latex centrifuging process. This grade of Solid rubber can be used as a filler in products such as shoe soles, rubber bands, car mats, etc. There are no standard technical specifications for this grade, hence, it is categorized under VGR (Visually Graded Rubber).
