Core Viewpoint - Despite the global economic slowdown, the domestic Chlorinated Polyethylene (CPE) industry has maintained production growth, with a production volume of 287,800 tons in the first half of 2025, representing a year-on-year increase of 1.25% [1][7]. Industry Overview - Chlorinated Polyethylene (CPE) is a high polymer material produced by chlorination modification of high-density polyethylene (HDPE), with chlorine content typically between 25% and 70% [2]. - CPE is widely used in various fields such as plastics, rubber, and coatings [2]. Industry Status - The growth in CPE production is attributed to the promotion of continuous chlorination technology, which has increased single-line production capacity by 30% and significantly improved production efficiency [1][7]. - The stable demand from traditional applications such as building waterproof materials and automotive seals has helped the industry counter external pressures through intelligent upgrades and green process iterations [1][7]. Consumption and Market Dynamics - In the first five months of 2025, China's CPE consumption reached 370,800 tons, a year-on-year increase of 5.71%, driven by ongoing investments in infrastructure [9]. - The construction sector remains the largest consumer of CPE, with stable demand for waterproof membranes and sealing strips, particularly influenced by green building policies [9]. Price and Production Capacity - By the end of June 2025, CPE prices fell to 7,078 yuan per ton, a year-on-year decrease of 12.44%, primarily due to fluctuations in international oil prices and increased chlorine production capacity in the northwest region [11][13]. - The CPE industry’s operating rate in June 2025 was 53.44%, a decrease of 2.63 percentage points month-on-month, reflecting reduced demand in the traditional construction off-season [13]. Key Enterprises - The CPE industry is characterized by a "leading enterprises dominate, small and medium-sized enterprises differentiate" competitive landscape [15]. - Hangzhou Keli Chemical, with a production capacity of 200,000 tons/year, focuses on high-end specialty CPE and holds over 30% market share in niche areas such as 5G base station casings and photovoltaic film [15]. - Shandong Weifang Yaxing Chemical, established in 1994, utilizes a unique hydrochloric acid phase suspension method for CPE production, achieving lower energy consumption and waste discharge compared to traditional methods [16]. Industry Development Trends - The CPE industry is expected to move towards more environmentally friendly and recyclable production methods, reducing harmful additives and improving waste management [20]. - There will be a greater emphasis on optimizing product performance and expanding application areas, particularly in emerging fields such as renewable energy and aerospace [21]. - Smart manufacturing and digital transformation are anticipated to become significant trends, enhancing production efficiency and product quality through automation and data analysis [22][23].
