Core Viewpoint - Polyimide (PI) is a critical high-performance engineering material in the "three electric systems" (battery, motor, and control) of electric vehicles, enhancing efficiency and safety [2]. Group 1: Application in Electric Vehicles - PI is ideal for motor insulation coatings due to its excellent high-temperature resistance and flame-retardant properties, addressing the breakdown issues in flat wire motors and improving motor efficiency [2]. - In the field of power batteries, PI is utilized in anode and cathode materials, separators, and PACK systems, with a focus on enhancing thermal stability while reducing costs [2]. Group 2: Company Developments - Boya Juliy has developed a PI flat wire winding varnish that offers higher insulation strength, effectively solving the breakdown problem in flat wire motors [2]. - The company is set to launch a high-performance polyimide resin and film project in Zhoushan, with an investment of 500 million yuan, expected to produce 12,600 tons of high-performance polyimide resin and 600 tons of electronic-grade polyimide film annually, generating an estimated annual output value of 600 million yuan [2]. Group 3: Industry Events - The co-founder and general manager of Ningbo Boya Juliy will present a report titled "Application of Polyimide in the Three Electric Systems of New Energy Vehicles" at the 2025 Polymer Industry Annual Conference [3].

Core Viewpoint - Sichuan Shangda Electronics Co., Ltd. has filed for bankruptcy liquidation due to financial difficulties exacerbated by industry challenges and rapid technological changes in the consumer electronics sector [1][4]. Company Overview - Sichuan Shangda was established in June 2019 with a registered capital of 300 million yuan, primarily focusing on flexible printed circuit boards (FPC) and other related products [2][3]. - The company became a key supplier for major domestic smartphone brands like Huawei, Xiaomi, and Vivo, achieving an annual production capacity of 250,000 pieces shortly after its establishment [2][3]. Financial Challenges - As of the bankruptcy filing, Sichuan Shangda reported total assets of 687 million yuan and liabilities of 826 million yuan, indicating a negative net asset of approximately 138 million yuan [4][8]. - The company faced a significant decline in orders for high-end FPC and COF due to a global downturn in consumer electronics demand and price wars in the electric vehicle supply chain [3][4]. - Initial production yield at the Sichuan facility was only 75%, below the industry breakeven point of 85%, leading to slow capacity ramp-up and financial strain [3][4]. Operational Issues - The company attempted to alleviate liquidity issues through equipment mortgage financing, but faced challenges due to poor asset liquidity and tightened credit conditions in the semiconductor sector [4]. - A decision was made to cease operations and terminate all employee contracts by May 30, 2025, due to the inability to sustain operations amid a funding crisis [4][7]. Legal Disputes - Sichuan Shangda is involved in multiple legal disputes with various companies over contracts related to sales, construction, and financing, indicating ongoing operational and financial complications [8].
