Branch inventory reconstruction

Accumulating holders Branches that accumulated shares during the window and still hold positive inventory; they are the absorbing side.

Distributing sellers Branches that built inventory earlier and have been selling it down; the remaining number estimates what has not cleared.

Net-short desks Trading-desk branches with negative inventory or net selling, often hedge, offsetting, or short-term flow. It is not automatically a bearish view.

What does 大立 do? Company profile

化學工業／化工上櫃（櫃買中心）

Overview

大立高分子工業股份有限公司為台灣上櫃普通股營運公司，股票代號4716，主要從事合成樹脂、電子化學材料及新材料相關產品。公司成立於1970年7月21日，公開發行日為1997年11月18日，2000年3月27日於櫃買中心上櫃。總公司位於高雄市永安區永工二路18號，主要生產據點包含高雄永安、仁武等地，子公司大立晶材位於南部科學園區高雄園區。依公開資訊及股市資料，截至近期資料，總經理為楊文忠；董事長資訊在不同來源間有時間差：2025年3月公告由洪玉婷接任，2026年6月11日又有董事會選任董事長公告，部分即時資料顯示董事長為成大職業帆船股份有限公司代表人洪玉升，部分基本資料仍顯示洪玉婷，因此本欄以「2026年6月仍需以公開資訊觀測站最新公告為準」註記。實收資本額近期資料約新台幣9.44億元，已發行股數約9,442.7萬股；部分2025年資料仍列8.95億元，可能反映除權增資或資料更新時點差異。2024年法說會揭露員工人數約114人（含大立晶材）。主要股東公開資訊有限，市場資料顯示董監持股約9.4%，前十大持股約10.24%；2026年3月董監持股資料顯示法人董事格林山有限公司持股約1,016張、約1.08%，質押比例高，另有成大職業帆船股份有限公司、格林山有限公司等法人董事相關資訊，確切持股結構應以年報及公開資訊觀測站為準。

Business

公司核心商業模式為研發、製造並銷售合成樹脂、電子材料及新材料，客戶多為塗料、接著劑、油墨、建材、FRP成型、電子顯示、抗靜電材料與特殊功能材料供應鏈。2024年產品營收結構依MoneyDJ彙整資料為：合成樹脂約94%、新材料產品約2%、太陽能發電約2%、電子材料約1%。合成樹脂為主要收入來源，產品包括醇酸樹脂、聚丙烯酸酯樹脂、飽和／不飽和聚酯樹脂、胺基樹脂、水性樹脂、塗料用助劑、色膏、受託加工等；用途涵蓋木器塗料、建築塗料、工業塗料、車輛塗料、3C塗料、接著劑、FRP積層膠殼、遊艇、浪板、人造大理石、鈕扣、汽車與電器部品、整體浴室組件、補土等。電子材料包含TN/STN/TFT液晶材料、FFS/IPS液晶、配向膜、PI樹脂等，公司歷史沿革顯示2003年與日本富士色素合作量產液晶，2007年購入日本ADEKA液晶事業。新材料包含PEDOT/PSS導電高分子樹脂與塗料、抗靜電膜與膠帶材料、透明電極、固態電容用導電材料、水合高分子抗菌材料、抗菌空氣濾網、抗菌抹布與相關清消應用。2024年法說會揭露新材料未來方向包含高延展性抗靜電薄膜、固態電容與透明電極導電材料、從水性跨至油性塗料市場，以及水合高分子在植物抗菌清消、畜牧養殖抗菌液、動物市場藥品、培養基與生物實驗器皿清消等應用。銷售區域依MoneyDJ資料，2024年台灣約52%、東南亞約20%、其他國家約17%、中國大陸約10%；不飽和聚酯樹脂台灣銷售量市占約3.35%。主要原料包括液態酐類、二甲苯、苯乙烯、異戊四醇、大豆油、聚碳酸酯樹脂、甘油、丙二醇等。

Outlook 2025–2028

2025至2028年展望可分為本業穩定、新材料選擇權與電子材料復甦三條線。第一，合成樹脂仍是營收主體，短中期成長取決於台灣及外銷塗料、接著劑、FRP、建材、車輛與工業需求循環；若油價與石化原料價格穩定，毛利率有機會改善，但公司規模較小，議價能力及固定成本吸收仍是挑戰。第二，環保法規與低VOC趨勢有利水性樹脂、無苯產品、降低SVHC原料使用等綠色友善配方，若能從傳統油性產品逐步提升水性、低溶劑與功能性產品比重，2025至2028年產品組合有改善空間。第三，新材料為較具成長性的方向：PEDOT/PSS導電高分子可對應抗靜電包裝、電子載帶／保護膜、透明電極、固態電容、5G與電子材料應用；水合高分子可對應抗菌濾網、畜牧與生物實驗清消等利基市場。第四，子公司大立晶材主攻膽固醇液晶材料，2023年媒體報導高雄園區廠房啟用、每月最大產能約2噸，並送樣兩岸面板大廠；若顯示器、反射式低功耗顯示或特殊液晶需求成長，2025至2028年可能成為小型但高彈性的成長動能。第五，風險包括：公司2024年產品結構仍高度集中於合成樹脂，電子材料與新材料合計占比低，商業化放量不確定；液晶與PI等關鍵材料競爭者多為德國、日本及中國大陸廠商，技術、客戶認證與量產穩定性門檻高；主要客戶未充分公開，終端需求與接單能見度有限；石化原料如苯乙烯、二甲苯、甘油、丙二醇與酐類價格波動會影響毛利；新材料若無法通過長期客戶驗證，可能僅維持小量利基；董監持股、質押、董事長更迭與檢調相關新聞可能造成治理面折價；另2026年已知月營收仍有波動，顯示本業景氣與新材料放量尚未穩定。整體而言，2025至2028年可期待低VOC水性樹脂、導電高分子、抗菌水合高分子及膽固醇液晶材料的利基成長，但在公開資料可驗證的範圍內，尚不足以斷定其能顯著改變營收結構。
