作为全国新能源汽车产业核心集聚区，浙江已形成整车制造、动力电池、汽车零部件协同发展的千亿级产业集群，宁波、台州、杭州、温州等地汽车配套产业链高度完善，零部件本土化配套率稳居全国前列。在新能源汽车精密制造体系中，各类硅胶配件看似不起眼，却是保障三电系统稳定运行、车载电子安全、底盘液压长效工作的核心基础部件，涵盖电池包密封硅胶垫、高压线束绝缘套管、车载减震硅胶件、耐高温密封胶圈等品类，直接决定整车的安全系数、续航稳定性与使用寿命。
As a core national hub for the new energy vehicle industry, Zhejiang has developed a hundred-billion-level industrial cluster with coordinated development in vehicle manufacturing, power batteries, and auto parts. Cities such as Ningbo, Taizhou, Hangzhou, and Wenzhou boast highly refined automobile supply chains, with the localization rate of parts consistently ranking among the top in the nation. Within the precision manufacturing system for new energy vehicles, various silicone components, though seemingly inconspicuous, are fundamental elements that ensure the stable operation of the three-electric system, the safety of onboard electronics, and the long-term functionality of chassis hydraulics. These components include battery pack sealing silicone pads, high-voltage wiring harness insulation sleeves, onboard shock-absorbing silicone parts, and high-temperature resistant sealing rings, which directly determine the vehicle’s safety, range stability, and service life.
车载工况复杂严苛，高温暴晒、低温寒冬、高压运转、油污侵蚀、高频震动等场景，对汽车级硅胶的耐候性、绝缘性、密封性、抗老化性提出了极致要求。相较于外资高端产品，浙江多数中小硅胶配套企业普遍存在配方技术短板，核心痛点集中在高端基材配比不精准、特种助剂添加失衡、硫化体系优化不足、耐高低温性能不达标等方面。通用型硅胶配方适配性差，量产产品易出现高温开裂、低温失弹、绝缘衰减、密封渗漏等问题，难以匹配蔚来、极氪、吉利等本土车企的高端量产标准，高端车载硅胶长期依赖进口或省外采购，成为浙江汽车零部件产业高端化突围的细微卡点。
The operating conditions of vehicles are complex and harsh. Scenarios such as high-temperature exposure, extreme cold, high-pressure operation, oil contamination, and high-frequency vibration place extreme demands on the weather resistance, insulation, sealing, and aging resistance of automotive-grade silicone. Compared with high-end foreign products, most small and medium-sized silicone suppliers in Zhejiang generally have shortcomings in formulation technology. The core issues are concentrated in inaccurate ratios of high-end raw materials, imbalance in the addition of special additives, insufficient optimization of the vulcanization system, and non-compliance with high and low-temperature performance standards. Generic silicone formulations have poor adaptability, and mass-produced products are prone to problems such as cracking at high temperatures, loss of elasticity at low temperatures, insulation degradation, and seal leakage, making it difficult to meet the high-end mass-production standards of local car manufacturers such as NIO, Zeekr, and Geely. High-end automotive silicone has long relied on imports or procurement from outside the province, becoming a subtle bottleneck for Zhejiang’s automotive parts industry in its pursuit of high-end development.
对于专注配套生产的中小制造企业而言，自主研发高端硅胶配方需要投入巨额设备成本、耗费数月试错周期，研发风险高、落地效率低。在此产业背景下，借力第三方专业科研机构突破技术壁垒，成为浙江硅胶配套企业转型升级、实现国产替代的最优路径。上海光研化学技术有限公司作为国家高新技术企业、中国分析测试协会会员单位，以中立客观的专业定位，深耕高分子材料配方分析与技术赋能，为浙江中小硅胶企业提供底层技术支撑，打通高端车载硅胶本土化升级通道。
For small and medium-sized manufacturing enterprises focused on supporting production, independently developing high-end silicone formulations requires huge equipment investments and months of trial-and-error, carrying high research risks and low implementation efficiency. Against this industrial backdrop, leveraging third-party professional research institutions to overcome technological barriers has become the optimal path for Zhejiang silicone supporting enterprises to transform, upgrade, and achieve domestic substitution. Shanghai Guangyan Chemical Technology Co., Ltd., as a national high-tech enterprise and a member of the Chinese Association for Analytical Testing, with a neutral and objective professional position, deeply engages in polymer material formulation analysis and technology empowerment, providing foundational technical support for small and medium-sized silicone enterprises in Zhejiang, and facilitating the localized upgrade of high-end automotive silicone.
