In recent years, the automotive manufacturing industry has been gradually adopting more... Modified engineering plastics These materials are being used to replace traditional metal materials, achieving lightweight designs and improving the vehicle’s fuel economy and environmental friendliness. The use of modified engineering plastics in automobiles is rapidly increasing, and a trend toward “plastic replacing steel” is emerging—meaning that plastic materials are increasingly substituting conventional steel and iron components. Among these, three types of modified engineering plastics—polypropylene (PP), polyamide (PA), and polycarbonate/ABS alloy (PC/ABS)—are widely employed in automotive manufacturing, offering diverse applications and significant advantages.
I. Polypropylene (PP)
PP is a modified plastic with properties including semi-crystallinity, high strength, high rigidity, chemical resistance, and excellent electrical and processing performance.
PP is considered the lightest plastic, with a density ranging from only 0.89 to 0.91 g/cm³. It boasts excellent overall performance and cost advantages, making it an ideal material for automotive lightweighting. PP is highly versatile and can be modified through various methods such as copolymerization, crosslinking, filling, and reinforcement, offering a wide range of formulations. As a result, it is the most widely used, most frequently employed, and fastest-growing type of plastic in automotive applications. Taking mid-range passenger cars as an example, PP-based materials are selected as often as 30% of the time, and their usage accounts for more than 50% of the total plastic content in the vehicle.
Over 60 types of automotive components are made from modified PP, among which bumpers, instrument panels, door inner panels, and air-conditioning components account for a significant share—collectively accounting for more than 60% of the total PP used in automobiles.
II. Polyamide (PA)
PA is a high-performance engineering plastic with excellent mechanical properties, good resistance to solvents, chemicals, and oils, superior weatherability, moderate flame retardancy, and ease of processing and molding.
They are widely used in fields such as automobiles, electrical appliances, and specialized equipment. Depending on the number of carbon atoms contained in the diamine and dicarboxylic acid or amino acid components of their structure, dozens of types of PAs can be produced, including PA6, PA66, PA11, and PA12. Among these, PA6 and PA66 are the primary grades of PA used in automotive applications; globally, more than half of all PA6 and PA66 is consumed in the automotive sector.
III. Polybutylene Terephthalate/ABS Alloy (PC/ABS)
PC/ABS is a modified plastic that boasts excellent impact strength, high heat resistance, outstanding processability, weather resistance, and chemical resistance.
It can be processed using techniques such as injection molding, extrusion, and calendering, and is widely used in the manufacture of automotive interior parts, exterior body components, electrical and electronic components, and more.
These modified engineering plastics not only help reduce vehicle weight and improve fuel efficiency, but also meet automotive requirements for safety, comfort, and aesthetics. As technology continues to advance, the automotive industry’s demand for modified engineering plastics will further increase, and more new types of plastic materials for automotive applications will emerge.

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.
