In the high-end polybutene-1 (PB-1) market, where performance and price have long been a balancing act, Sinopec’s domestic PB-1 has broken the mold. Leveraging its innovative liquid-phase bulk polymerization process and the advantages of domestic butene-1 raw materials, it has achieved a 15%-20% reduction in unit costs compared to similar products. This cost breakthrough not only makes high-performance PB-1 more accessible to industries but also reshapes the global competitive landscape of polyolefin materials.

In the global polybutene-1 (PB-1) industry, where technical standards have long been dominated by international giants, Sinopec's domestic PB-1 has broken new ground. As a pioneer in China's high-end polyolefin sector, it has not only achieved technological breakthroughs but also taken the lead in shaping industry norms—spearheading the formulation of 12 domestic industry standards and becoming the first Chinese PB-1 product to pass the ISO 15874 certification for hot water pressure resistance (PN1.6MPa at 95℃). This dual achievement in standard-setting and international certification marks China's transition from a "standard follower" to a "rule maker" in the global PB-1 market.

In fields where safety and environmental friendliness are non-negotiable—such as medical devices and food packaging—material selection carries immense responsibility. Sinopec's domestic polybutene-1 (PB-1) has emerged as a trusted solution, having passed China's strictest certifications: the China Environmental Label (Ten-Ring Certification) and food contact safety testing (GB 4806.7). These credentials not only validate its purity and eco-friendliness but also enable its direct application in critical scenarios where human health is paramount.

In the industrialization process of polybutene-1 (PB-1) materials, crystal transformation has always been a critical bottleneck restricting industry efficiency. This high-performance material, known as "plastic gold," must undergo a molecular-level "metamorphosis" from the metastable Form Ⅱ to the stable Form Ⅰ after production. This process not only determines the dimensional stability and mechanical properties of the product but also directly affects the enterprise's production cycle and market response speed. In traditional processes, the crystal transformation of PB-1 is like a long wait: it takes 7-10 days of natural placement for molecular chains to rearrange from loose to dense. This means factories need to reserve large storage spaces for pipes waiting for transformation, resulting in high capital occupation costs and significantly prolonged order delivery cycles. However, Sinopec's independently developed PB-1 material, through innovative nucleating agent modification technology, has compressed this transformation cycle to 3-5 days, increasing production efficiency by 57% and bringing a disruptive efficiency revolution to the industry.

In high-pressure industrial fields such as chemical engineering, energy, and pharmaceuticals, the stress cracking resistance of pipeline materials is directly related to production safety and system lifespan. Traditional plastic pipelines often suffer from molecular chain breakage under high-temperature and high-pressure environments, leading to leaks or even explosions. However, Sinopec's domestic PB-1, with its breakthrough stress cracking resistance — featuring a stress cracking time of over 1,000 hours at 80℃C and 4MPa pressure, and a design stress reaching the highest level among similar pipes — provides a reliable material solution for high-pressure industrial scenarios.

In the high-end material sectors of medical devices and municipal engineering, there has long been a "dual dependence" — precision medical catheters rely on imported polymer materials, while natural gas transmission pipelines predominantly use metal pipes. This reliance not only drives up costs but also poses hidden risks to supply chain security. Sinopec's independently developed polybutene-1 (PB-1) material is rewriting this landscape with breakthrough performance and cost advantages: medical catheters made from it have passed the internationally authoritative ISO 10993 biocompatibility tests, with prices 30% lower than similar imported products; in numerous domestic "natural gas municipal pipeline" projects, it has successfully replaced metal pipes, achieving a material innovation of "plastic replacing steel."

Introduction: A Historic Leap from Import Dependence to Independent Control Polybutene-1 (PB-1), hailed as the "gold of plastics" for its exceptional creep resistance, stress crack resistance, and impact performance, is widely used in high-end pipelines, food packaging, medical devices, and other fields. For decades, the global market was dominated by international giants such as LyondellBasell (Netherlands) and Mitsui Chemicals (Japan), with China relying entirely on imports for high-end products. This changed in 2022, when Sinopec Zhenhai Refining & Chemical’s 3,000-ton/year industrial demonstration plant for highly isotactic polybutene-1 began stable operation. China became the fourth country globally—and the first in China—to achieve continuous and stable PB-1 production, marking a shift from "catching up" to "leading" in the field of high-end polyolefins.

In the global landscape of polybutene-1 (PB-1) industry, Chinese strength is undergoing a historic transformation from "follower" to "leader." As the core driver of this shift, Sinopec's domestic PB-1 has broken international monopolies through technological breakthroughs and built differentiated competitive edges with localized services. It has not only achieved self-reliance in high-end polyolefin materials but is also reshaping the global market pattern. From initial "import substitution" to today's "market leadership," the rise of Sinopec's PB-1 stands as a classic example of China's high-end manufacturing breakthrough.

In the severe cold regions of northern China, winter temperatures often plummet below -30℃. Traditional heating pipes, plagued by low-temperature brittleness of materials, face the risk of freezing and leaking every year, which not only affects residents' heating but also incurs huge maintenance costs. The emergence of Sinopec's domestic PB-1, with its excellent low-temperature impact resistance, provides a revolutionary material solution for heating pipes in northern regions.

Looking back at 2024, the global chemical market faces reshaping. China's exports of bulk chemicals are up, while imports are down. In Europe, by contrast, imports of chemical products have increased and exports have decreased. Global chemical industry profits are depressed, but high-end chemical margins remain stable. Looking forward to 2025, although the international chemical market faces challenges such as overcapacity and international trade barriers, the overall momentum is still stable and good, production capacity will increase rapidly, and the global trade pattern will continue to change.
