A \"cutting-edge\" product in the coating industry – PolyShine Polyurea, a new type of highly durable protective material. When a fresh egg is dropped from a height of 15 meters and bounces several times, its surface remains intact； The two-ton car drove over it, and the empty aluminum can didn’t deform at all ； Two blows to the same car door: one spot was penetrated, while the other only showed slight dents… This amazing phenomenon occurs simply because of the use of a cutting-edge product from the coating industry – PolyShine polyurea, a new type of highly durable protective material. 　　Founded by Meng Qingshi, a professor and doctoral supervisor at Shenyang Aerospace University, Shenyang Jusheng New Materials Technology Co., Ltd. (hereinafter referred to as Jusheng New Materials) leverages its strong research capabilities and cutting-edge products to break the foreign monopoly on advanced protective material technologies, making this \"cutting-edge technology\" available to ordinary people. 　　Focusing on high-end materials, with comprehensive improvements in performance. The R&D center for new ultra-strong and durable protective materials at Jusheng New Materials, located in Shenyang’s Advanced Manufacturing Industrial Park, is the place where these highly performant protective materials were developed. 　　“The coating thickness of this protective panel for new energy vehicle batteries is less than 2 millimeters, with less than 1 kilogram of polyurea protective material applied; key performance indicators such as elongation at break, tear strength, and tensile strength all meet the customer’s requirements. ”said Liu Zhenhuan, the production safety manager at Jusheng New Materials. 　　“The protective layer of this new energy vehicle’s battery pack is made using a matte spraying process, which provides the battery pack’s chassis with impact resistance, wear resistance, and corrosion protection; it is capable of withstanding the impact of stones the size of eggs moving at a speed of 120 kilometers per hour. Through the intelligent impact monitoring system for battery packs, it is possible to monitor in real time the impact resistance and damage dynamics of the battery packs. ”Meng Bohao, director of the Jusheng New Materials Laboratory, pointed to the impact cloud image on the monitoring display and told the reporters. 　　Yu Yin, the R&D director of Jusheng New Materials, was involved in every stage of the development of Jusheng’s new type of ultra-strong and durable protective polyurea material. She pointed to a small fish tank and explained that the main material used for the tank is polyurea, and the fish inside have been alive for over a year. “The new polyurea material we have developed contains no solvents and is highly biocompatible, posing no impact on the human body. ” 　　Polyurea protective materials are widely used in fields such as waterproofing, corrosion prevention, wear resistance, and explosion protection, and are known as \"universal\" coatings. “Our focus is on developing high-end polyurea materials, which is primarily reflected in the term ‘super tough’. ”Meng Qingshi, chairman of Jusheng New Materials, said. 　　After 8 years of intensive research efforts, Meng Qingshi’s research team developed high-performance matrix materials such as polyurea elastomers, as well as key two-dimensional nanomaterials, to create lightweight protective composite materials with excellent mechanical properties. Compared to the higher-end polyurea matrix materials used in the industry, PolySheng’s new protective materials exhibit an increase in elongation at break of 50%–200%, a increase in tear strength of over 50%, and an increase in tensile strength of over 50%. They achieve significant improvements in terms of lightweight properties, high strength and toughness, impact resistance, resistance to collapse, and high wear resistance. 　　Self-ignition of batteries occurs from time to time in new energy vehicle protection chassis as a result of external impacts. The excellent impact resistance of Jusheng polyurea’s new ultra-strong protective material, which becomes even stronger under high strain rates, perfectly meets the protection requirements for new energy vehicle batteries. 　　Meng Qingshi explained that Jusheng New Materials has developed the only domestic technology for aviation-grade polyurea-based, ultra-strong and highly durable protective materials. “Protective materials for new energy vehicles is our target market. We hope that the results will be put into practice at an early date to enable mass production, thereby contributing to the safe operation of new energy vehicles. ”
