Additives for processing natural rubber and their application in small rubber plantations

Abstract: Se presenta una revisión de literatura sobre cómo los aditivos usados en los procesos de beneficio del caucho natural modifican las propiedades del látex líquido o caucho seco en forma de láminas o coágulos, productos que pueden obtenerse en plantaciones de caucho como las que abundan en Colombia. Se consideran las ventajas y desventajas del uso de los aditivos, resaltando la disminución del impacto ambiental y suministrando criterios para reemplazar sustancias tradicionalmente usadas pero que implican riesgos… Show more

“…In a typical rubber compounding line, there is the need for accurate metering of all the additives to the base polymer to obtain a uniform and homogenous mix of desired properties [7,8]. Despite the unique properties of pristine rubbers such as elasticity, high rebound energy, and excellent damping characteristics amongst others, they are required to be compounded with other materials before meeting desired requirements due to their susceptibility to thermal and oxidative degradation [14][15][16]. Compounding involves the incorporation into the rubber matrix of some ingredients known as additives to achieve desired properties such as processability, stiffness, weatherability, and bondability amongst others.…”

“…An elaborate list of compounding ingredients are Base polymer, Vulcanizing agent, Accelerator for cross-linking reaction, Accelerator modifiers (activators, retarders, inhibitors), Processing aids [plasticizers, peptizers, factice, dispersing aids, tackifiers, process oil, lubricants, softeners, and extenders], Fillers, Antistatic agents, Anti-degradants (antioxidant, antiozonant, stabilizers), Special purpose additives (colourants and pigments, flame retarders, deodorants, blowing agents, stiffening agents, abrasives, diluents, integral bonding additives, and wetting agents). It E-ISSN: 2321-9637 Available online at www.ijrat.org 2 doi: 10.32622/ijrat.111202311 can be seen that the overall total number of ingredients in a sophisticated rubber formulation can be very large [15][16]. Castor oil, known primarily for its medicinal use as a cathartic [to release stress and tension], is now used as an industrial raw material for the preparation of chemical derivatives used in coatings, urethane derivatives, surfactants and dispersants, cosmetics, lubricants and textiles [17].…”
