Recently, China's scientific research and innovation team made a major breakthrough in the research of new technologies for polybutene inside the kettle, and developed a new material PB-A for polybutylene alloy resin for floor heating pipes, breaking the long-term technical monopoly and blockade in the field.
At present, most commonly used plastic pipes for floor heating in China are made of PEX, heat-resistant polyethylene (PE-RT), PPR, and polybutene (PB), among which polybutene is a polymer inert polymer and is the world's One of the most cutting-edge chemical materials. According to Ren Xuebin, deputy general manager of Shantou Tokyo Bo Petrochemical Co., Ltd., “Foreign companies hold the core of this technology, and China’s market for more than 60% of this area is monopolized by foreign products. The limited supply of China's products, and the high price, has led to this kind of excellent material has not been widely promoted and popularized in China.
'The new material PB-A has excellent creep properties, high chemical stability, not only anti-aging, corrosion resistance, especially in the performance of high resistance, low temperature and pressure capacity, has reached or exceeded the performance of PB materials ' Ren Xuebin told reporters that the material can produce thin wall, large diameter, light weight, no scaling, high impact plastic tube, easy to handle and install.
'The traditional PB pipe sculpting time is slow, it takes 7-10 days. The new technology we developed can make the new material PB-A only 3-5 days, and the time is shortened by 57%, which greatly improves the cycle time of the forming process.' According to researchers from the Jingbo Chemical Research Institute, PB-A has a wide range of raw material applications. It can be used in PP modification to increase toughness and improve its impact strength. In traditional TPE applications, it can replace PVC to make sheets and tubes. No need to add plasticizers to obtain the required flexibility, thus avoiding the safety problems of vinyl chloride due to the addition of plasticized PVC and the health hazards caused by the addition of plasticizers. 'Test shows that the new material is used. The production of plastic pipes can be safely used for more than 50 years. The plastic pipe market, including floor heating, will become a new growth point for PB-A material applications in the areas of future urbanization, shanty town reconstruction, rural water supply, and transformation of saline-alkali soil.
It is understood that at present domestic and foreign olefin resources are abundant, and its application area is limited to low-end products. The breakthrough of this technology makes it possible to extend olefin resources to high-value-added products. 'We will study the material in the automotive field and on the seabed or underground. Cables, optical cables and other applications. ' According to researchers, PB-A thermoplastic elastomer excellent electrical insulation, waterproof penetration, tear resistance, abrasion resistance, is the manufacture of submarine or underground cable, optical cable insulation coating The ideal material for the layer. 'As a local large-scale petrochemical company, we have a wealth of high-quality olefinic resources and will build a national industrial base for lightweight, high-strength alloys and new materials. We will vigorously promote high-end, functional, and professional development of our products.'
