Waxes are used in the rubber industry for the production of rubber hoses, conveyor belts, rubber toys, assembly gloves, tires, seals and many other similar applications in eraser. Waxes have the following applications in the rubber industry: It acts as an anti-ozonant, migrating on the surface a thin protective layer is formed which ensures protection against ozone attack and brittleness. Paraffin wax offers rapid protection for newly produced products but in the case of microcrystalline wax it guarantees slow-release and long-lasting protection. The delicately formulated balance between paraffin waxes and microcrystalline waxes ensures migration control ensuring fast action and long life. The wax is used as a carrier for protective chemicals. The wax is used as a release agent, anti -aging, plasticizer and lubricant in the rubber and tire industry [26]. Rubber exposed to air or sunlight produces cracks, and if tensile stress is applied, the cracks appear clearly. To avoid these cracks, the use of amine and wax antioxidants is known so far. Usually amines undergo a selective chemical reaction with ozone and consume the ozone in the surface layer of the rubber to prevent the rubber from aging under static or dynamic conditions, while the wax embedded in the rubber exudes onto the surface to form a film thin, which prevents the rubber from coming into contact with ozone producing an antioxidant effect, especially in static conditions. Furthermore, generally the two types of agents indicated above are used together and simultaneously. Antioxidant rubber wax refers to the latter, i.e. static antioxidant [27]. Various antioxidant rubber waxes have been available since ancient times...... middle of paper ...... depends on the solubility/mobility or sorption/desorption characteristics of the specific wax under a given set of environmental conditions [ 28].The following are the factors that influence migration: Time Storage temperature after curing Wax concentration Wax composition Amount and type of filler Thinner oil is present. These factors make it difficult to choose a wax that works effectively over a wide temperature range. Paraffin waxes usually protect better at low exposure temperatures, while microcrystalline waxes are more effective at high temperatures. In this case, wax blends offer a wider protective temperature range. There is an optimal migration temperature for each wax, and dynamic thermal analysis (DTA) can predict this optimal value. The best ozone resistance is also achieved at the temperature corresponding to optimal wax migration
