According to reports by Japanese media, Sumitomo Rubber Industries Co., Ltd. held the "Green Tyre Technical Symposium" at its Japan Kobe Corporation.

Since the introduction of the "Low Fuel Consumption Tire Labeling System" in Japan's domestic market in 2010, Sumitomo Rubber's " low fuel consumption tire " products have ranked No. 1 in domestic sales for two consecutive years. Therefore, in order to introduce this tire development technology and to promote the exchange of information among technicians, Sumitomo Rubber has planned this seminar.

It is reported that the “Low Fuel Tire Labeling System” sets a benchmark for the tire's rolling resistance performance and wetland anti-skid performance, and further standardizes the product and ranks it, thereby promoting the popularization of low-burnout tires. The “Low Fuel Tire” mark was printed on products that meet certain benchmarks. Sumitomo Rubber actively standardized the products at the beginning of the implementation of the system.

According to reports, in terms of raw materials, Sumitomo Rubber Co., Ltd. began developing tires that do not rely on fossil resources such as petroleum and fossil fuels in 2001. In 2006, it released the ENASAVEES 801, which was used in non-petroleum natural resources, and its utilization rate reached 70%. The use of environmental protection tires has been further improved to 97%, "ENASAVE 97, and the remaining 3% of the elements are anti-aging agents, vulcanization accelerators, and carbon black.

Sumitomo Rubber has developed special technologies for the synthesis of aromatic compounds from natural resources and has introduced the technology into factories and production. It can be used not only in tires but also in synthetic rubber and rubber chemicals. It is reported that Sumitomo Rubber will also discuss the choice of materials and the conditions of combustion to establish new technologies for converting biological resources into carbon components.

In terms of low fuel consumption performance, Sumitomo Rubber has always considered how to reduce tire rotation resistance. Since starting the low-fuel tire labeling system in 2010, it has actively promoted research and development of low-fuel tires. At present, it is striving to release in the year 2014 a new type of tire with a 50% reduction in rolling resistance compared to previous tires.

In addition, at the 2011 Tokyo Motor Show in Japan, Sumitomo Rubber stated that it has trialed 100% of non-oil natural resources tires and plans to adjust its mass production system to strive to be listed in the fall of 2013.

Regarding mass production of non-oil natural resources tires, the head of the first division of the Sumitomo Rubber Materials Development Headquarters Material and Tian Xiao made the following explanations for the origin of the company's ENR (Evolution and Natural Rubber) technology and ENASAVE97: "120 years ago globally The first pneumatic tire was introduced, and 100% used only natural resources. After that, the development of the petrochemical industry led to the continuous evolution of tires, but now we have to return to the truth, that is, 100% use of natural resources. In order to further improve the rubber properties, first of all from the change The quality of natural rubber begins."

According to Hetian, the key to developing 100% oil-exotic natural resources tires lies in "converting all organic matter into biological resources." It is necessary to burn natural resources to produce plant carbon black, and to use aromatic compounds from plant biomass to synthesize aromatic compounds. of.
