Curing enhancers

Anorin-38 has also shown an interesting effect as a multifunctional additive (a single additive to replace many of the conventional additives) for natural rubber (NR). It showed excellent blending behavior and compatibility with NR. Aorin-38 enhances the tensile properties and percent elongation, decreases fatigue, acts as an antioxidant and antiozonant, and positively affects many of the other properties, apart from acting as a process aid and a cure enhancer [183-186]. 

Our preliminary formulation work using NVP agreed with reported observations of cure enhancement using this monomer under ambient conditions. To investigate the component interactions we decided to examine the behavior of the neat monomers followed by the interactions of monomer-NVP, resin-NVP, and finally more complex mixtures containing either NVP or NMP.

Moreover, for the fiber-filled composites, the scorch, and cure time is low when compared to those of an unfilled one because of the increase in the mixing time [8, 9]. Ismail et al. [10] investigated the particle size on the processing parameters of the oil pahn wood flour (OPWFJ/NR composites. They found a decrease in the scorch time with increase of OPWF content. At any filler loading, OPWF with larger particle size shows shorter torque value and scorch time. The cure enhancement for these composites is attributed to the filler-related parameters such as surface area, surface reactivity, particle size, and moisture content. Comparison of the cure... 

Citric acid is used in carbonated beverages to provide tartness, modify and enhance flavors, and chelate trace metals. It is often added to jams and jellies to control pH and provide tartness. It is used in cured and freeze-dried meat products to protect the amino acids (qv) and improve water retention. Bakers use it to improve the flavor of fmit fillings in baked goods. Because citric acid is a good chelator for trace metals, it is used as an antioxidant synergist in fats and oils, and as a preservative in frozen fish and shellfish (7) (see Antioxidaisits). 

Fillers. Materials used as fillers (qv) in mbber can also be classified as acidic, basic, or neutral. Furnace blacks, ie, HAF, FEF, or SRF, are somewhat basic. As such, they can have an activating effect on sulfur cure rates. Furthermore, carbon blacks have been found to promote formation of mono/disulfide cross-links thereby helping minimize reversion and enhance aging properties. 

Pseudothermoplastic resin systems, which are formed as conventional thermoplastic materials and then cured or postcured in a manner similar to that used for thermosetting resins to enhance high temperature properties. 

In order to enhance the reactivity of the chlorine atom, a second reactive monomer can be adopted giving dual cure sites. According to the Hterature, the second monomer can contain carboxyl (22—24), cyanoalkyl (25), hydroxypropyl (26), or epoxy groups (27,28).
