Core Viewpoint - Nylon (polyamide) is a key engineering plastic with high strength, wear resistance, and chemical corrosion resistance, widely used in automotive, electronics, textiles, and new energy sectors. However, its inherent aging issues, such as yellowing and mechanical performance degradation, remain industry pain points [1][3]. Group 1: Aging Mechanism of Nylon - The aging of nylon is caused by both internal and external factors, including the amide bond structure and alkyl chain that are susceptible to free radical reactions under heat, light, oxygen, and water [4]. - External factors like UV radiation, high-temperature processing, and humid environments significantly accelerate material degradation, especially in applications like electric vehicles and outdoor engineering [4]. - Key aging mechanisms include thermal oxidation leading to free radical chain reactions, photodegradation triggered by UV light, and hydrolysis catalyzed by water molecules [4][5]. Group 2: Solutions to Aging Issues - The core strategy to delay nylon aging involves blocking heat sources, isolating oxygen, and eliminating free radicals, with additives playing a crucial role in interrupting these reaction chains [5]. - New materials technology company has developed a range of weather-resistant additives, including antioxidants and light stabilizers, to enhance nylon's durability [5][10]. Group 3: Product Innovations - High-performance antioxidants like AO-3398 and P-EPQ have been introduced, improving thermal stability and resistance to hydrolysis, with temperature resistance exceeding 300°C [10][11]. - New multifunctional nylon additives, such as H3391, enhance processing stability and reduce breakage rates during nylon spinning, while also improving heat aging performance [13]. - The high-temperature yellowing agent H3311 effectively protects nylon products from oxidation and yellowing during processing, especially under high shear and temperature conditions [15]. Group 4: Domestic Technology Breakthroughs - The company has successfully developed a domestic solution for a patented product, reducing market prices from 300,000 yuan/ton to around 100,000 yuan/ton, with an annual production capacity of 300-400 tons [16]. - The company aims to not only replace imports but also address industry pain points through original design [16][17]. Group 5: Industry Trends and Opportunities - The nylon industry in China is accelerating towards high-end and low-carbon transformation, driven by the domestic production of key raw materials and breakthroughs in synthesis technologies for high-temperature and long-chain nylons [19]. - Emerging applications in electric vehicles, electronics, and intelligent robotics present significant opportunities and challenges for nylon modification and additive industries [19].
