COMPARISON WITH RSS GRADES
With the consuming industry moving towards Technical Standards for processing such as TS specifications, and now to IATF, there came an inevitable need to standardize the raw material processing methods. As a result the consuming industry has begun to prefer Block Rubber which as its name suggest is Technically Specified Natural Rubber having specifications & parameters that can be test in the laboratory and having consistency in the same unlike sheet rubber (RSS Grades)
