The manufacturing of new energy vehicles puts extremely high requirements on the reliability, environmental protection, weather resistance and adaptability of industrial tapes. Tapes have become key materials to ensure battery safety, improve vehicle performance and achieve lightweight. This paper focuses on the application of LVZHIMEI industrial tapes in core scenarios of new energy vehicles such as battery packaging, wire harness fixing and lightweight component bonding, deeply analyzes the performance requirements and product advantages in each scenario, and shows how the products adapt to the green supply chain of new energy vehicles to help the high-quality development of the industry.
As new energy vehicles upgrade to high cruising range, high safety and lightweight, the application scenarios of industrial tapes continue to expand, and performance requirements continue to rise. Targeting the working conditions of the new energy vehicle industry, LVZHIMEI has customized a series of special industrial tapes, covering core parts such as batteries, wire harnesses, body and interior. Through strict performance testing and scenario verification, it has become a qualified supplier of many new energy vehicle enterprises, providing stable support for vehicle safety and performance.
Battery packaging is one of the core application scenarios of new energy vehicles, which has extreme requirements on the high-temperature resistance, insulation, flame retardancy and waterproof performance of tapes. LVZHIMEI polyimide high-temperature insulation tape is specially designed for battery tab protection and cell fixing. It has short-term 300℃ and long-term 250℃ temperature resistance, breakdown voltage ≥30kV/mm, and excellent insulation performance. It can effectively isolate the tab from the cell shell and prevent short circuit risk; at the same time, it has passed UL94 V-0 flame retardant certification, does not burn or drip when exposed to fire, providing double protection for battery safety. In battery PACK packaging, LVZHIMEI waterproof foam tape has excellent waterproof and sealing performance (IP67 level), temperature resistance and shock resistance, which can effectively seal the gaps of the battery pack, prevent moisture and dust from entering, and buffer the vibration impact during driving to protect the battery module.
The wire harness fixing scenario has strict requirements on the bonding strength, weather resistance, shock resistance and environmental protection of the tape. New energy vehicles have a large number of wire harnesses with wide distribution, which need to withstand -40℃ to 150℃ temperature cycles, long-term vibration and chemical corrosion. LVZHIMEI eco-friendly wire harness tape adopts a solvent-free adhesive formula with low VOC emissions, complying with green supply chain requirements. It also has strong bonding strength (180° peel strength ≥1.5N/mm), UV aging resistance and chemical corrosion resistance, which can effectively fix the wire harness, avoid loose wear and extend the service life of the wire harness. In the lightweight component bonding scenario, LVZHIMEI solvent-free structural adhesive can replace traditional mechanical fixing (bolts, rivets) for bonding lightweight materials such as aluminum alloy and carbon fiber. It has high bonding strength, can withstand long-term vibration and temperature changes, and at the same time reduces the body weight (3-5kg per vehicle), improving the cruising range.
The performance verification of industrial tapes in the new energy vehicle field is extremely strict. LVZHIMEI products have passed multiple rigorous certifications such as -40℃ to 150℃, 1000 temperature cycle tests, 5000-hour UV aging tests, and 1000-hour salt spray tests, with stable and reliable performance. In addition, LVZHIMEI can customize the width, thickness, color and performance parameters
