The "rare earth gold" tire developed by using the "rare earth gold" rubber compound new material is the latest scientific and technological achievement created by the new double star. Under the background of realizing the "double carbon" strategic goal, it has contributed the wisdom of the double star to the global users and the society.

Appraisal by the expert group: The new "rare earth gold" rubber composite material is made of special rare earth neodymium-based butadiene rubber + natural rubber + high-performance carbon black and other formulas, and is processed by a special mixing process, with mature technology and excellent performance. , which can be promoted in batches. "Rare earth gold" tires are products designed and produced using "rare earth gold" rubber composite material + FZW (full zero winding technology) + unique patterns. "Rare earth gold" tires have the distinctive features of super fuel saving and super wear resistance. The rolling resistance can reach 3.8 to 4.5, and the mileage can reach 500,000 kilometers (two retreads can reach 1 million kilometers), which is an international leading level.

Graphene tire laboratory honed a sword in 5 years

In March 2016, the country's first graphene tire central laboratory project started construction in Shuangxing. In April 2018, the project was listed as a key project by Shandong Province. At the end of 2018, Shuangxing "graphene" tires were successfully developed, but due to the high cost, there was no large-scale market promotion.

After that, according to the characteristics of rare earth neodymium cis-butadiene rubber, Shuangxing combined technical experts from Europe, the United States and South Korea to further research and develop rare earth neodymium cis-butadiene rubber + natural rubber + high-performance carbon black and other formulas, and make full use of Shuangxing The manufacturing advantages of the "Industry 4.0" factory have developed a new "rare earth gold" rubber composite material.

At the same time, Shuangxing fully combines the special needs of the Chinese market, using "rare earth gold" rubber composite material + FZW (full zero winding technology) + unique pattern to design and produce TBR "rare earth gold" tires that have reached the international leading level.

Double Star Tire strives to become the first tire company in the world to achieve carbon neutrality

The rolling resistance of "rare earth gold" tires can be reduced to 3.8 to 4.5. According to comparable data and expert analysis, if a large trailer runs for 1 million kilometers and uses "rare earth gold" tires with a rolling resistance of 4.5, it can save 63,000 liters of fuel (calculated at 7 yuan per liter, it can save 440,000 liters of fuel). yuan, which is equivalent to using 293 tires for free); the fuel consumption saved by a car is equivalent to reducing carbon emissions by 168 tons.

If the total number of the above-mentioned vehicles is 8 million, the annual fuel saving will exceed 100 billion liters, which is nearly two Daqing oilfields' annual oil production. Reduce carbon emissions by more than 250 million tons and carbon dioxide absorption by more than 10 million acres of forests in one year. It not only reduces the operating cost of car owners, but also fulfills a great social responsibility.

On the other hand, if China's annual output of truck and passenger tires is calculated at 130 million pieces (with a service life of about 200,000 kilometers), and all double-star "rare earth gold" tires are used, calculated according to a service life of 500,000 kilometers (without retreading), about 80 million can be reduced. The 80 million tires can reduce carbon emissions by about 3.6 million tons a year according to the carbon emission level of existing ordinary enterprises, and greatly reduce the resource consumption of front-end raw materials.

According to relevant personnel of Double Star, relevant measures are currently being formulated to actively implement the "dual carbon" strategy, and strive to make Double Star Tire will become the first company in the global automotive tire industry to achieve carbon neutrality in 2023.
