Nylon (PA) boasts a range of excellent properties, including high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, and ease of processing and molding. As a result, it has become one of the widely used thermoplastic engineering plastics both domestically and internationally.
However, in practical applications, different usage conditions and environments place varying demands on the performance of nylon. For example, components such as electric drill and motor housings, pump impellers, bearings, and all-plastic fans for diesel engines and air conditioners require nylon materials to exhibit high strength, high rigidity, and excellent dimensional stability. Since nylon has poor low-temperature toughness, it needs to be toughened and modified accordingly in such cases. In some outdoor applications, nylon materials must undergo weathering-resistant modification when exposed to long-term outdoor environments.
The reinforcing materials used in glass-reinforced nylon primarily include fibrous substances such as glass fibers, carbon fibers, and whiskers; among these, glass-fiber reinforcement is the most widely adopted. Glass-fiber reinforcement can significantly enhance the material's rigidity, strength, and hardness, while also markedly improving its dimensional stability and heat resistance.
Since nylon itself lacks sufficient strength, its strength can be enhanced by adding 10–30% fibers. In particular, a fiber content of 30% is widely recognized as the most suitable proportion. Some applications even involve adding 40–50% fibers; depending on the specific requirements of different products and combined with appropriate formulations, such additions can also achieve successful results.
The following is with PA66 material For example
1. High-strength fiberglass-reinforced product
The reinforced nylon material with a fiberglass addition ratio of 40-50% is primarily suitable for manufacturing high-strength gears and high-performance components for specialized equipment.
Applications: Various precision gears
PA66+GF boasts high rigidity, dimensional stability, noise reduction, wear resistance, quiet operation, lubricity, and antistatic properties.
2. Medium-strength product reinforced with glass fiber
The reinforced nylon material with a fiberglass addition ratio of 25-35% is primarily used for manufacturing medium-strength components such as automotive parts, housings for power tools, fan blades and impellers for electrical appliances, tableware, and toys.
Application 1: Automotive Parts
The automotive PA66+GF material can be used in engine intake manifolds, engine hood covers, vehicle underbodies, engine fan blades, and automotive air-conditioning evaporators and condensers, among other components.
(1) The intake manifold is made of PA66 + 30% GF, with long-term temperature resistance exceeding 140℃ for over 2,000 hours.
(2) Automotive underbody mudguards, with PA66+30%GF engine fan blades, require excellent toughness and strength, as well as very low deformation and dimensional stability.
(3) Automotive air-conditioning evaporators require excellent warping resistance, long-term heat resistance, hydrolysis resistance, high dimensional stability, as well as high strength and toughness—made from PA66 + 15% glass fiber + 10% talc powder.
Application 2: Various connectors for electronic components
This is halogen-free flame-retardant PA66+35%GF, widely used in various electronic connectors. Electronic connectors require high flowability, dimensional stability, and excellent electrical performance; some also demand flame-retardant properties. In such cases, only modified materials can fully meet these requirements.
Application 3: Various high-power fan blades and impellers
High-rigidity, high-toughness, low-warpage, creep-resistant, hydrolysis-resistant modified PA66 + 30% GF material.
Application 4: Tableware
High-temperature resistant, food-grade, high-flow, reinforced, PA66 + 30% GF.
Application 5: Toy Industry
Toy gun stocks, drone propellers, and motor mounts for toys typically use medium- to high-strength modified plastics, such as PA66+30%GF and PA66+30% carbon fiber.
3. Low-Intensity Glass-Fiber Reinforced Products
Reinforced nylon materials with a fiberglass addition ratio of 10-20% are primarily used in the manufacture of components such as connectors, tactile switches, and medical devices for electronic and electrical products.
Application: Medical Device Field
Nylon materials offer mechanical strength and a skin-friendly feel that are not found in conventional materials. Medical devices such as foot drop correctors, rehabilitation wheelchairs, and medical care beds typically require components with a certain load-bearing capacity; therefore, PA66 + 15% GF is commonly chosen for these applications.
By adding an appropriate amount of fiber to nylon, the strength and stiffness of reinforced nylon can be significantly improved. Depending on the specific requirements of different products, various fiber-reinforcement ratios can be selected, and a suitable formulation can be used to ensure the quality and performance of the final product.

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.
