The core advantages of Chinese PVC stabilizers compared to foreign countries are concentrated in cost, industrial chain, environmental transformation, and response efficiency, while there is still room for improvement in high-end technology and standard discourse power.
Firstly, the cost competitiveness is significant. As the world's largest PVC producer in terms of raw materials and scale (with a production capacity of 39.7% in 2024), the upstream petrochemical and oil chemical systems are well-established, and the production capacity of key raw materials such as epoxy soybean oil accounts for more than 65% of the world's total, resulting in lower procurement and production costs. Secondly, in terms of manufacturing costs, the average production cost of domestic enterprises is 15% -20% lower than that of international enterprises. The advantages of large-scale products such as calcium zinc stabilizers are more prominent, and they have strong price competitiveness in the mid to low end market.
Secondly, the complete industrial chain and supply resilience. From raw materials and additives to terminal applications, a supply chain with internal circulation as the main focus and external collaboration is formed, with high node density and strong risk resistance, and less affected by geographical and trade barriers.
Quick response, close to the world's largest PVC consumer market, able to quickly match customized needs in downstream fields such as building materials, automobiles, wires and cables, with leading iteration speed.
Localization guarantee: The localization rate of key raw materials and additives continues to increase, and the self-sufficiency rate of high-end organic tin will reach 49% by 2024, reducing import dependence.
There is also the acceleration of environmental transformation and compliance. Policies such as "dual carbon" and new pollutant control have forced the industry to transform towards calcium zinc, organotin, and bio based stabilizers. By 2024, the proportion of environmentally friendly products in hard products will reach 68.5%, and the proportion of lead salts will decrease to 18.7%. The number of products that have passed international certifications such as REACH, RoHS, and FDA has increased by 53% year-on-year in 2024, with 82% coming from cluster enterprises in East and South China, indicating a rapid improvement in compliance capabilities.
Technological breakthroughs: Progress has been made in areas such as calcium zinc composites, rare earth stabilizers, and bio based synergists, with indicators such as thermal stability time and migration approaching international advanced levels.
Finally, research and patent development grew rapidly. Innovation investment will reach 1.58 billion yuan in research and development investment by 2023, a year-on-year increase of 22.7%. The number of patent applications accounts for 64% of the global total, and the cooperation between industry, academia, and research is mature.
