Core Viewpoint - The polycarbonate (PC) industry is at a critical stage of "climbing over hurdles," emphasizing the need for high-end, differentiated, and green development to transition from price competition to value competition [1][2]. Industry Overview - China's PC production capacity has significantly increased from 1.66 million tons in 2019 to 3.81 million tons in 2024, accounting for 48% of global capacity, with a compound annual growth rate of 15.5% over five years [1]. - The apparent demand for PC in 2024 is projected to reach 3.6 million tons, approximately half of the global demand [1]. Structural Challenges - The PC industry faces structural contradictions, with low-end capacity surplus and insufficient high-end supply. The self-sufficiency rate for general-grade products exceeds 100%, while the domestic production rate for high-end grades like medical and optical grades is below 30% [2]. - Since 2021, China's PC production capacity has surpassed apparent consumption, leading to an average capacity utilization rate of only 65% over the past five years [2]. Financial Performance - The average gross profit margin for the industry fell to negative values in the first quarter of 2025, indicating challenges from price competition and cost pressures [2]. Growth Opportunities - The decline in PC prices and its superior performance have spurred rapid growth in emerging sectors such as new energy vehicles and high-end medical applications, presenting new growth opportunities for the PC industry [2]. Strategic Recommendations - The industry should focus on technological advancements to achieve product high-endization, aiming to increase the proportion of high-end grades to over 40% [2]. - Embracing green transformation in line with the "dual carbon" goals by developing recycling systems for waste PC and bio-based PC is essential for promoting a circular economy [2]. - Collaborative efforts along the industrial chain are necessary to mitigate risks, with a focus on establishing application standards in high-end fields like aerospace and neurosurgery [2].
规划产能规模惊人 赛道拥挤的碳酸二甲酯行业亟待整合
"十四五"以来,新能源汽车的快速发展带动各类锂电化学品需求暴增,DMC这种过去产量几万至十几 万吨的小众产品引来众多企业布局。据隆众资讯统计数据,最近4年国内DMC产能复合增长率28%, 2024年底总产能达到356.5万吨。但产能利用率大幅下滑,2024年下半年全行业进入亏损状态,部分装 置被迫停车以缓解成本及销售压力。 聚碳酸酯(PC)是DMC最大下游,占比五成左右,承载了近年来DMC消费端的增长;其次是电解液溶 剂,占比达46%,但电解液溶剂发展变缓,终端需求跟进清淡,供需矛盾加剧,利润压缩甚至亏损。不 过,国内价格不断下行之下刺激了PC出口,2024年PC出口量同比增长148%。 目前DMC这一赛道已经非常拥挤,"参赛企业"共有33家,除了较早布局并形成完整电解液溶剂、添加 剂产品群的石大胜华(603026),后来居上成为碳酸酯行业龙头的华鲁恒升(600426),依托石化产业 链联产DMC的利华益、海科新源(301292),依托丙二醇联产DMC的德普新材料,更有恒力石化 (600346)、陕煤集团榆林化学这样的"大块头"企业强势入局。 7月以来,装置停车检修供应紧张叠加下游锂电池电解液需求增加,国内碳 ...
