The petrochemical fiber industry is experiencing a significant cyclical recovery. Hengli Petrochemical reported a net profit of 7.2 billion yuan in the first half of 2026, a 136% year-on-year increase, surpassing its full-year 2025 profit. For professionals tracking the polyester supply chain, this performance forecast sends a clear signal: the cyclical trough has passed, and the profit elasticity of leading companies is materializing.
Core Drivers of Profit Growth
Hengli's profit surge is no accident. Industry data shows that processing margins for refining, PTA, and polyester segments all improved significantly in H1 2026. The refining segment benefited from expanding margins for bulk chemicals like aromatics and olefins, becoming the largest profit contributor. While the PTA segment faced industry-wide processing fee pressure, Hengli maintained above-average profitability due to its massive 16.6 million-ton annual capacity and integrated raw material supply. The polyester new materials segment saw steady production and sales, with profits recovering as downstream demand gradually rebounded.
Behind this margin recovery is an improved supply-demand balance. Over the past two years, the petrochemical fiber industry suffered from overcapacity and weak demand. But since 2026, recovering orders in downstream textile and apparel sectors have driven steady growth in polyester product demand, facilitating price transmission from refining to polyester. Hengli's performance epitomizes this industry trend.
Advantages of Integrated Layout in Cyclical Hedging
Hengli's deeply integrated "oil, coal, and chemical" industrial ecosystem demonstrates unique resilience during this cyclical recovery. The company has built core capacities including a 20-million-ton refining-chemical integration unit, a 6-million-ton coal chemical plant, and a 1.5-million-ton ethylene plant, with all chain units running at high loads. This layout allows flexible procurement adjustments based on crude oil and coal price fluctuations, while dynamically optimizing product mix according to margin changes across segments.
For buyers and downstream factories, this means Hengli's supply chain stability far exceeds that of single-product companies. When PTA processing fees are low, refining profits can act as a buffer; when polyester demand picks up, integrated capacity can quickly ramp up. This synergy is the core reason Hengli's half-year profit surpassed its full-year 2025 figure, offering a reference for other industry players.
Transmission Effects on Downstream Textile Industry
Hengli's profit recovery has clear positive implications for the downstream textile chain. As one of China's largest PTA and polyester producers, Hengli's high operating rates signal ample upstream raw material supply and stable pricing. With the traditional peak season approaching in the second half of 2026, downstream weaving mills can expect more stable raw material costs and reliable supply.
From a product category perspective, the recovery in polyester new materials profitability directly impacts the market performance of textile raw materials like polyester filament and staple fiber. If upstream margin recovery continues, raw material prices may rise moderately, but sharp fluctuations are unlikely given the pace of end-demand recovery. For fabric and garment manufacturers, the current period may represent a window to lock in raw material costs.
Industry Outlook and Practical Recommendations
Hengli is transitioning from a cyclical petrochemical giant to a comprehensive materials platform with both cyclical elasticity and growth certainty. Its investments in high-value-added areas like functional polyester film and lithium battery separators will gradually reduce dependence on traditional textile raw material cycles. This strategic shift signals that competition in the petrochemical fiber industry is moving from scale expansion to technological barriers and product differentiation.
