Cutting-edge technology has enabled Linglong Tires to launch a god-level new product, surpassing the EU's "AA1" grade quality

With the increasing depletion of oil resources and the intensification of the greenhouse effect, energy conservation, emission reduction and environmental protection have been receiving more and more attention from countries around the world. In 2010, countries such as the European Union and Japan raised the requirements for tire rolling resistance, wet skid and noise to the regulatory level.

To meet the highest requirements of the EU labeling Law, the Research Institute of Shandong Linglong Tire Co., Ltd. and the Advanced Elastomer Materials Research Center of Beijing University of Chemical Technology have established a special research team to develop new high-level and high-grade tire products in response to the highest grade "AA1" level of the EU labeling Law.

New Product Introduction

The new product, leveraging the research platforms of Linglong Tire Research Institute and the State Key Laboratory of Organic-Inorganic Composites at Beijing University of Chemical Technology, organically integrates fundamental research such as cross-scale simulation calculations and the percolation-viscoelastic mechanism of nano-reinforced rubber with the development of high-performance tread rubber nano-composite material formulas. It scientifically applies special new materials and develops advanced continuous mixing processes. The network structure regulation and functional coupling of multi-component and multi-scale materials have been achieved, and the tire structure and pattern arrangement have been scientifically designed at the same time.

The new product can effectively reduce the sliding distance between the tires and the ground during braking, greatly enhancing the safety performance of the tires on wet roads. At the same time, it can also significantly lower the energy loss of the tires during use, saving the vehicle's fuel consumption.

In July 2019, the development of two specifications of products was completed, both reaching the AA1 level. The rolling resistance of the 205/55R16 and 235/55R19 specification products is below 6.0, the wet slip index is above 1.60, and the passing noise is 68dB. The indicators meet the AA1 level of the EU Labeling Act, and the performance of wet slip and rolling resistance parameters is superior to the requirements of the EU labeling regulations. At present, this product has been successfully applied in Linglong Tire's domestic and international vehicle supporting projects.

Research and development strength

The current highest grade of the EU labeling Law is AA1, which means A wet slip index, A rolling resistance and a noise level of 1. The successful development of Linglong Tire's AA1 project fully demonstrates the company's R&D capabilities and the power of cooperation among industry, academia and research. It provides a solid technical guarantee for the company to continue to expand the European market and enhance brand value.

Behind Linglong Tyre's leading R&D capabilities lies its consistent investment in research and development and innovation over the years. It is understood that Linglong Tire has established R&D institutions in Zhaoyuan, Yantai, Beijing, Shanghai, Germany and the United States. It possesses a national-level industrial design center, a national recognized enterprise technology center and a national accredited laboratory, thus building an integrated R&D pattern covering the world.

Up to now, Linglong Tyre has participated in the formulation and revision of 91 national and industry standards, undertaken 11 national-level innovation projects, and has been granted over 700 patents in total. Its tire ownership ranks among the top in China's tyre enterprises.

Science and technology are the primary productive forces. In recent years, Linglong has successfully developed graphene-reinforced tread tires, 3D-printed ultra-low heat generation and high-cut-resistant polyurethane tires, racing tires, run-flat tires, low-odor tires, dandelion rubber tires, etc. It has also participated in the basic research on the design and manufacture of advanced composite materials and structures for national large aircraft radial tires. And independently develop special products for urban rail transit. It has won two national-level science and technology awards, namely the Second Prize of National Technological Invention and the Second Prize of National Science and Technology Progress.

In the era of black swan events, industry competition is becoming increasingly fierce. While expanding the market, quality is also an important part of enhancing competitiveness. With strong R&D capabilities and the creation of new products, Linglong Tire is accelerating its pace towards high-end development. In the process of high-quality growth, Linglong Tire will continue to enhance its own strength and strive to achieve the goal of becoming a world-class tire enterprise!
