聚碳酸酯行业破局“内卷”剑指高端

Core Viewpoint - The PC industry is transitioning from "price competition" to "value competition" by focusing on high-end, differentiated, and green development to overcome current challenges [2][3]. Industry Overview - The PC industry in China has seen significant capacity growth, increasing from 1.66 million tons in 2019 to 3.81 million tons by 2024, accounting for 48% of global capacity with a compound annual growth rate of 15.5% over five years [2]. - The apparent demand for PC in 2024 is projected to reach 3.6 million tons, representing about half of global demand [2]. Current Challenges - The industry faces structural contradictions with low-end capacity surplus and insufficient high-end supply, where 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% [3]. - Since 2021, China's PC capacity has surpassed apparent consumption, leading to an average capacity utilization rate of only 65% over the past five years [3]. - The average gross profit margin for the industry fell to negative values in Q1 2025, indicating challenges from price competition and cost pressures [3]. Future Development Strategies - The industry aims to achieve product high-endization through technological advancements, targeting core goals such as optical-grade transparency of ≥92%, medical-grade certification, and mass production of bio-based PC, with a goal to increase the share of high-end grades to over 40% [3]. - Embracing the "dual carbon" era, the industry is focusing on green transformation by developing recycling systems for waste PC and bio-based PC, promoting a circular economy [3]. - Collaborative efforts along the industrial chain are encouraged to mitigate risks, with a focus on establishing application standards in high-end fields like aerospace and neurosurgery [3].
