身為亞洲區具代表性的 BPA 製造商，長春集團深知產品品質與穩定供應對下游客戶開發進度與市場競爭力的關鍵性影響。我們不僅致力於供應高純度、低雜質的 BPA 原料，並且以協作式開發模式，積極參與聚碳酸酯、環氧樹脂與特殊工程塑料等下游產業的配方優化與產品共創。透過與各領域研發團隊的深度交流與技術支持，長春集團正打造從原料到應用、從實驗室到量產的整合價值鏈，協助客戶縮短開發時程、提升產品表現，並共同面對產業升級與永續挑戰。

 

雙酚A的多元應用：不只是環氧樹脂與聚碳酸酯

BPA 最為人熟知的用途包括：

• 聚碳酸酯（Polycarbonate, PC）：此類高性能塑料具備卓越的機械強度與透明度，適用於光學鏡片、醫療器材、耐衝擊透明板材、LED 燈罩以及電子顯示面板等。其具備良好的耐熱與加工性質，是多功能用途的理想材料。
• 環氧樹脂（Epoxy Resin）：廣泛應用於電路板（PCB）、半導體封裝材料、工業黏合劑、耐蝕塗料以及風電葉片等複合結構中。BPA 所製得的環氧樹脂擁有優異的黏結性、耐化性與介電穩定性，是電子與能源產業不可或缺的關鍵材料。
• SMC/BMC 複合材料：作為結構型複合材料基礎，這些以 BPA 為基礎的高分子材料可應用於汽車車殼、引擎蓋、電器外殼與工業構件，實現重量減輕與強度提升的設計目標。

於此同時，BPA 衍生產品早已在新興高端應用領域中受到重視：

• 電子級環氧樹脂：隨著5G通訊、AI伺服器與高頻電子設備的發展，市場對低離子雜質、高 Tg、低介電常數與優異熱導率的需求提升，使得電子級 BPA 衍生環氧體系成為主流選項之一。
• 高耐熱聚合物：如 PES（聚醚砜）、PEI（聚醚酰亞胺）等工程塑料，常用於航太、高溫電器與特殊膜材中，其合成單體即仰賴 BPA 為關鍵反應元件。
• 醫療級材料：隨著醫療器材朝向微創化、高透明性與長效性發展，BPA 衍生的聚碳酸酯在人工腎臟、注射器、輸液裝置與體內植入器材中，提供高生物相容性與穩定性，挑戰製程潔淨度與 QA/QC 管理極限。

 

BPA 製程創新：從高產率轉向「高純度 + 低碳排」

為滿足高階應用的品質需求與 ESG 標準，BPA 製程研發期望往下列方向採取進步，並持續透過技術創新與流程優化，強化其在永續性與高階應用市場的競爭優勢：

高純度 BPA 等級

• 為了因應電子、光學與醫療等高端應用場景對化學穩定性與光學透明度的嚴格要求，BPA 的純度控制已推向極限，進入 ppb（十億分之一）等級的雜質管理。
• 雜質控制對象包括酚類殘留、重金屬離子、有機氯化物等微量污染源，避免影響下游聚合反應的活性與產品性能。
• 為此，我們導入多級萃取純化程序、智慧製程監控（如 NIR 分析）與閉環循環精餾系統，以穩定生產具備極高反應選擇性與低內應力的 BPA 單體。

低能耗 / 低碳排 製程技術

• 為回應全球減碳趨勢與供應鏈永續要求，BPA 製程逐步轉型為低碳排與高能效製造模式。
• 我們積極導入熱整合設計，透過餘熱回收系統優化能源利用效率，同時應用連續式反應器降低單位產品能耗並提升反應收率。
• 此外，在廢氣與廢液處理上也導入 VOC 吸附再生塔、熱裂解系統與高效能換熱器，結合智慧控制系統以即時調控反應條件與能量平衡，提升整體製程的環保與經濟效益。

副產物資源化利用

• 為實現零排放目標，長春集團對 BPA 製程中產生的副產氯酚、甲基酚與其他芳香族化合物，已建立完整的資源化利用機制。
• 將副產物重新導入其他反應段作為起始原料，或透過精製回收技術供應至下游用於生產含氟樹脂、熱固性塗料、高性能表面改質劑等特用化學品。
• 此舉不僅提高整體原料利用率，也大幅減少廢棄物處理成本與環境衝擊，展現化工製程與永續管理的雙重競爭力。

Bisphenol A: Beyond a Commodity—Driving Innovation in Advanced Materials

In today’s rapidly evolving landscape of high-performance materials, Bisphenol A (BPA) is no longer merely a fundamental chemical raw material—it has become a critical intermediate that enables industrial transformation across electronics, automotive, biomedical, and other advanced sectors. Polymers and resins derived from BPA exhibit outstanding properties, including superior mechanical strength, thermal stability, optical clarity, and reactivity, making them indispensable in the development of high-value-added products. Applications continue to expand in both breadth and depth, particularly in high-end electronic packaging, medical devices, and green energy technologies.

As one of Asia’s leading BPA producers, Chang Chun Group recognizes the crucial role of consistent quality and supply reliability in accelerating customer development timelines and sustaining competitiveness. We are committed not only to supplying high-purity, low-impurity BPA, but also to engaging in collaborative development with downstream partners in polycarbonate (PC), epoxy resin, and specialty engineering plastics. By working closely with R&D teams across various industries, we are building an integrated value chain—from raw materials to applications, from lab-scale to mass production—to help our partners reduce time-to-market, enhance product performance, and jointly meet the challenges of industrial upgrading and sustainability.

BPA’s Expanding Applications: More than Just Epoxy and Polycarbonate

The most recognized applications of BPA include:

• Polycarbonate (PC): A high-performance plastic renowned for its mechanical strength and optical clarity. It is widely used in optical lenses, medical instruments, impact-resistant transparent sheets, LED housings, and electronic display panels. With excellent heat resistance and processability, PC is an ideal material for multifunctional use.

• Epoxy Resin: Commonly found in PCBs, semiconductor encapsulation, industrial adhesives, anti-corrosive coatings, and wind turbine blades. BPA-based epoxies offer exceptional adhesion, chemical resistance, and dielectric stability—making them essential to the electronics and energy sectors.

• SMC/BMC Composites: These BPA-based structural materials are used in automotive body panels, engine hoods, electrical enclosures, and industrial components, supporting weight reduction and structural reinforcement goals.

Beyond these established areas, BPA derivatives are gaining prominence in emerging, high-end applications:

• Electronics-Grade Epoxy Resins: With the growth of 5G communications, AI servers, and high-frequency electronics, the demand for low ionic impurities, high Tg, low dielectric constants, and excellent thermal conductivity is driving the adoption of electronics-grade BPA-based systems.

• High-Temperature Engineering Plastics: BPA is a critical monomer in the production of polymers such as PES (polyethersulfone) and PEI (polyetherimide), widely used in aerospace, high-temperature electronics, and specialty membranes.

• Medical-Grade Materials: As medical devices evolve toward miniaturization, transparency, and long-term reliability, BPA-derived polycarbonates are favored for their biocompatibility and stability in applications like artificial kidneys, syringes, infusion systems, and implantable devices—where they meet stringent process hygiene and QA/QC standards.

BPA Process Innovation: From High Yield to “High Purity + Low Carbon”

To meet the demands of high-end applications and ESG standards, BPA manufacturing is advancing in the following directions, reinforcing its competitive edge in both sustainability and advanced technologies through continuous innovation and process optimization:

• Ultra-High Purity Grades:
  In response to the rigorous requirements of electronics, optics, and medical applications, BPA purity control has reached ppb (parts-per-billion) levels. Impurities such as residual phenols, heavy metals, and organic chlorides are tightly managed to ensure optimal polymerization and downstream product performance.

  We implement multi-stage purification processes, smart process control (e.g., NIR analysis), and closed-loop distillation systems to consistently deliver BPA monomers with high reactivity selectivity and minimal internal stress.

• Low Energy / Low Carbon Process Technologies:
  In alignment with global decarbonization and sustainable supply chain goals, we are transitioning toward low-carbon, energy-efficient BPA manufacturing.

  Through thermal integration and waste heat recovery, we improve energy utilization while adopting continuous reactors to reduce unit energy consumption and boost reaction yield. VOC adsorption towers, thermal cracking units, and high-efficiency heat exchangers are integrated with smart control systems to manage reaction conditions and energy balances in real-time, maximizing environmental and economic performance.

• Byproduct Resource Utilization:
  To achieve near-zero emissions, Chang Chun Group has developed a comprehensive utilization system for byproducts such as chlorophenols, cresols, and other aromatic compounds generated during BPA production.

  These byproducts are recycled as feedstocks for other chemical processes or refined for downstream applications such as fluoropolymers, thermosetting coatings, and high-performance surface modifiers. This enhances overall resource efficiency, reduces waste treatment costs, and minimizes environmental impact—demonstrating our dual commitment to process excellence and sustainability.
