Curing Characteristics of Natural Rubber Filled
Its effects on curing characteristics were investigated in comparison with commercial gypsum and calcium carbonate. These fillers were characterized by an X-ray diffractometer before being mixed with natural rubber at various amounts. Several ingredients necessary for curing via sulfur system were also incorporated.
