Natural rubber is a type of rubber made form milky white liquid of some plants commonly known as latex. It is released in case of cutting of plants. Natural rubbers are elastomers which occur naturally. About 99 percent of world’s natural rubber is produced from rubber tree called as hevea brasiliensis. Natural rubber is isoprene polymer with chemical formula of (C5H8)n which can be pulled apart adding elasticity property in the natural rubber. The preparation of natural rubber involves five basic steps such as: rubber tapping, mastication, calendering, extrusion and vulcanization. Natural rubber can withstand high water resistance, flexibility, cutting and tearing resistance, wear and abrasion resistance and other chemical resistance with a temperature range of 58 to 212 degrees Fahrenheit. Natural rubber adheres quickly to other materials and provides high tensile strength. All the above properties increases the use of natural rubber in applications such as anti-vibration mounts, drive couplings, springs, bearings and rubber bands. Natural rubber demand is high by the manufacturers because of the low cost of manufacturing with satisfactory performance in many applications. According to the Association of Natural Rubber Producing Countries (ANRPC), the demand of natural rubber is going to increase in third quarter of 2020 with increase in demand in automobile sector.
