In modern industry, polypropylene (PP) has become the material of choice for many sectors thanks to its advantages such as lightweight construction, chemical resistance, and low cost. However, conventional PP has limited temperature resistance—typically below **100°C**—which restricts its use in high-temperature environments. To address this issue, **modified PP** has emerged! By adding reinforcing agents, fillers, or blending it with other polymers, the temperature resistance of modified PP has been significantly enhanced. So then... Modified PP Just how high a temperature can it withstand? In which fields does it truly shine? In this article, the editors of Zhenshun Plastics will answer these questions for you one by one!
I. Temperature Resistance of Modified PP: Breaking Through the Limits!
The melting point of conventional PP is approximately **160°C–170°C**, and its long-term operating temperature typically ranges between **80°C and 100°C**. However, through modification techniques, the temperature resistance of PP can be significantly enhanced:
1. Short-term high-temperature resistance: Certain modified PP materials can be used briefly at **120°C–140°C**, making them suitable for applications that require brief exposure to high temperatures.
2. Long-term temperature resistance: By adding glass fibers, mineral fillers, or blending with other high-temperature-resistant polymers, the long-term use temperature of modified PP can be increased to **110°C–130°C**, and even higher.
3. Special Modified PP: Some high-performance modified PPs (such as those with added carbon fibers or special heat-resistant additives) can withstand temperatures of 150°C or higher, making them suitable for extreme high-temperature environments.
II. Temperature-Resistance Enhancement Technology for Modified PP: How Is It Achieved?
The enhanced temperature resistance of modified PP primarily relies on the following technologies:
1. Glass fiber reinforcement: The addition of glass fibers can significantly enhance the heat resistance and mechanical strength of PP, enabling it to maintain stability even at high temperatures.
2. Mineral Fillers: The addition of mineral fillers such as talc and mica not only enhances the temperature resistance of PP but also improves its rigidity and dimensional stability.
3. Blending Modification: Blending PP with other high-temperature-resistant polymers (such as PA and PPS) can significantly enhance its heat resistance.
4. Heat-resistant additives: By adding antioxidants, heat stabilizers, and other such agents, the aging process of PP at high temperatures is delayed.
III. Temperature-Resistant Applications of Modified PP: A “Jack-of-all-trades” in High-Temperature Fields
Thanks to its excellent temperature resistance, modified PP has found wide application in the following fields:
1. Automotive industry:
- Engine peripheral components (such as fan shroud, intake manifold)
- High-temperature-resistant interior parts (such as dashboards and door panels)
- Battery housing (new energy vehicles)
2. Home appliance industry:
- Microwave oven components
- Electric kettle casing
- Coffee machine parts
3. Electronics and Electrical Engineering:
- High-temperature-resistant sockets and switches
- Wire and cable insulation layer

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.
