Effect of multifunction process aids on NR-based silica compounds

In this research, multifunction process aids in natural rubber-based (NR) silica compounds are studied. NR is a non-polar rubber in nature whereas silica is the polar material. Accordingly, it couldn’t be mixed and dispersed easily in the rubber matrix. To address processing issues, a process aid is required. NR has a tendency toward high reversion during vulcanization over a prolonged time; anti-reversion chemicals are used to protect this high reversion issue. The main function of multifunction process aids is to achieve the properties of process aids and anti-reversion chemicals. Processing behavior, dynamic properties and physical properties have all been studied and are discussed in this paper.
