Rubber Nano Products (Pty) Ltd [RNP] holds technology that allows for the creation of chemically specific activators for the different major classes of accelerators used in rubber vulcanization with sulfur. These accelerator classes are based on the chemical species forming the active portion of the accelerator type. RNP technology allows for variation of the substrate used and can create activators from almost any material used in rubber manufacture. Sulfur, silica, carbon black and even activating stearic acid are among the many possibilities.
The RNP products allow for reduction and rationalization of zinc oxide and zinc content in rubber article manufacture. This is simultaneously achieved with substantial cure and productivity advantages which can also be leveraged as cure press temperature reduction with energy savings. The behaviour of the coactivators of RNP allows for property performances that are not typical of standard ZnO rubber formulations using the standard accelerators.
