　　Energy conservation and emission reduction have become a major theme in the automotive industry, and lightweight design is one of the most effective measures for achieving these goals. Due to technological requirements, new-energy vehicles inevitably weigh more than conventional vehicles. As a result, the demand for lightweight materials in new-energy vehicles is even more urgent. However, selecting the right plastic materials for encapsulating the power batteries of new-energy vehicles is crucial. Below is a material-selection guide to help you choose plastic materials that offer excellent performance and reliability.

　　Power Battery-packaging plastic The materials must meet specific requirements in terms of high-temperature resistance, chemical corrosion resistance, electrical insulation, mechanical strength, flame retardancy, and environmental friendliness, to ensure the performance and safety of the battery system in automotive applications.
　　1. High-temperature resistance: During operation, the power battery systems of new-energy vehicles generate high temperatures. Therefore, plastic materials must exhibit excellent high-temperature resistance to maintain stable performance and structural integrity.
　　2. Chemical Corrosion Resistance: Batteries contain various electrolytes and chemical substances, so plastic materials must exhibit excellent chemical corrosion resistance to prevent reactions with the internal battery components and ensure the normal operation of the battery system.
　　3. Electrical Insulation Performance: The battery packaging material must possess excellent electrical insulation performance to prevent internal electrical short circuits or leakage, thereby ensuring the safety and stability of the battery system.
　　4. Mechanical Strength: Plastic materials must possess sufficient mechanical strength to ensure the structural integrity of the battery pack, enabling it to withstand vibrations and impacts during vehicle operation and thereby guaranteeing the reliability and durability of the battery system.
　　5. Flame-retardant performance: Considering the safety of battery systems, it is essential to select plastic materials with excellent flame-retardant properties when choosing materials, in order to reduce the risk of fires and safety incidents.
　　6. Environmental Friendliness: Emphasize environmental protection and sustainable development, giving priority to plastic materials that meet environmental standards and possess recyclable or biodegradable properties, thereby reducing negative impacts on the environment.

　　Selection of Plastic Packaging Materials for New Energy Power Battery Packs
　　1. Module housing
　　Currently, in addition to the need for lightweighting, the plastic housings of battery modules also demand “design integration” of materials, in order to meet the growing demand for higher power density in both batteries and entire vehicles. Therefore, today’s material requirements can be summarized into two main categories: First, the material must exhibit excellent mechanical properties, including good impact resistance and a certain degree of toughness; second, it must possess favorable processing characteristics that enable it to be fabricated into thin-walled components and parts with complex geometries. Polyphenylene Oxide (PPO) is currently one of the popular materials used in new-energy vehicles, particularly in the battery sector.
　　2. Sealing element
　　Power battery seals are used to seal the edges of batteries. They must exhibit excellent high-temperature resistance, chemical resistance, and sealing performance, as well as a certain degree of elasticity and wear resistance. Commonly used seal materials include polypropylene (PP) and polybutylene terephthalate (PBT).
　　3. Battery tray
　　As a structural component of the battery, the tray also accounts for a significant portion of the overall weight. It is required to have excellent strength and stiffness, as well as good corrosion resistance and high-temperature performance. Commonly used tray materials include polycarbonate (PC) and polyphenylene oxide (PPO).

[Zhen Shun Plastics] Introduction to Flame-Retardant PC/ABS Material for New Energy Charging Pile Housings

Every departure is an opportunity to encounter even more breathtaking scenery; every journey together is a chance to forge deeper, warmer bonds. In 2025, Zhen Shun Plastics’ annual group tour arrived as scheduled. Leaving behind the hustle and bustle of work, we set off toward Changbai Mountain in Northeast China, drawn by our longing for its majestic mountains and rivers. During our four-day trip, we journeyed from the humid warmth of Lingnan to the crisp freshness of northern lands, stepping from the urban clamor into nature’s serene tranquility. Every leg of the journey was filled with surprises, and every moment was worth treasuring. First Stop: Changbai Mountain—Heavenly Lake Bestows Its True Beauty On the day of departure, the sunshine was just right, and our team began our journey to Heavenly Lake. Along the way, we were deeply captivated by the stunning scenery. As the altitude gradually rose, the distant Tian Shan mountain range came into view. The rolling hills, set against the blue sky, looked majestic and awe-inspiring. After much anticipation, we finally arrived at Heavenly Lake. What luck! It was our first time visiting Changbai Mountain, yet we were greeted with the sight of Heavenly Lake itself! The crystal-clear, deep-blue waters instantly amazed everyone present. Exclamations of wonder and cheers echoed through the air. Everyone rushed to get closer to this "peerless beauty," snapping photos to capture this unforgettable moment. The magic and beauty of nature always touch our hearts directly. Photos simply can’t convey the震撼 (shocking) power of the real scene—so it truly is said, “Seeing is believing.” You really have to see these sights with your own eyes. The blue sky, white clouds, mountains, and lakes—this very moment perfectly embodied the idea that “life is an open wilderness.” After admiring Heavenly Lake, we took another off-road vehicle back to the trailhead, then switched to an eco-friendly bus to reach the waterfall attraction. The Changbai Mountain Waterfall was truly spectacular—the water roared fiercely, its sound echoing for miles. It looked like a giant silver ribbon suspended high above the canyon. Whether viewed from afar or up close, the waterfall was breathtaking. Beneath the falls, the immense impact created swirling mist, making the scene absolutely magnificent. The river flowing down the waterfall ebbed and flowed, winding and twisting, stirring our senses. Second Stop: Guangdong Village—Stepping Into a Pastoral Poem of Korean Ethnic Charm As dusk approached, we arrived at a Korean ethnic village. The setting sun was gently coloring the land with a soft glow. Gray tiles and white walls turned orange, and the eaves were edged with gold—a scene straight out of a folk painting. We stepped into a local home, where the hosts warmly welcomed us and shared with us some of their local culinary customs. Third Stop: Tumen Border Crossing—A Glimpse of Two Countries at a Glance Tumen faces Namyang, North Korea, across the river. Though separated by just a single river, it feels like two entirely different worlds. Standing on the banks of the Tumen River and gazing across, we could clearly see the houses and streets of Namyang, North Korea. Scenes of daily life unfolded before our eyes through the binoculars. Listening to our guide share stories about the neighboring country’s customs and traditions, and watching the scenes across the river, we, as Chinese citizens, felt a strong sense of happiness and pride welling up inside us. We became even more grateful for our country’s peace and prosperity. Fourth Stop: Yanji—Folklore Park—Playing Princess of Yanji for a Day “You really must visit Yanji! Take a stroll in the evening breeze of the university town, put on an elegant long dress, and freeze time in the lantern-lit Folklore Park, becoming a princess of Yanji for a day.” Yanji, with its unique ethnic charm and immersive cultural experiences, has become a “fairytale city” in the hearts of countless tourists. From the snowy winter to the lush spring and summer, this place weaves a dreamlike journey through time with traditional costumes, lanterns, and a bowl of ginseng chicken soup. As our four-day trip in Northeast China drew to a close, we found ourselves immersed in the lantern-lit ambiance of Yanji’s Folklore Park. From the breathtaking azure of Heavenly Lake on Changbai Mountain to the misty spray from the waterfall dampening our clothes; from the warm smiles of Korean families in Guangdong Village bathed in the sunset, to the surge of patriotism we felt when gazing across the Tumen River at our neighbor country—each moment was like a sparkling pearl, strung together to form our cherished memories as the Zhen Shun Plastics family. This journey not only allowed us to take a break from the busy pace of work but also deepened our understanding of each other amidst the mountains and culture, strengthening our team spirit even further. Those moments—cheering together by Heavenly Lake, taking photos of each other in the Folklore Park, sharing delicious meals around the table—all will remain the warmest source of strength in our hearts. This wonderful experience wouldn’t have been possible without the company’s thoughtfulness and care. Thank you, Zhen Shun Plastics, for always putting the happiness of every employee first and creating opportunities for us to connect with nature, embrace culture, and strengthen our bonds through our annual group tour.
