(1)The first propylene-based elastomer pilot plant in China

12moon6day,The first propylene-based elastomer in China(PBE)The pilot plant successfully completed the entire production process at the Tianjin Scientific Experimental Base of Beijing Research Institute of Chemical Industry,Achieve a successful first drive。PBEThe pilot plant was successfully started up,This marks the successful completion of the first phase of the construction of the Tianjin Scientific Experimental Base of the Beijing Institute of Chemical Technology,Achieved13All the devices were started up successfully at one time。

Propylene elastomer(PBE)The pilot plant uses the solution polymerization technology independently developed by Beijing Institute of Chemical Technology,Using self-developed catalysts,Preparation of a series of new propylene-based elastomer products,It is an important platform for the research and development of new materials technology。

Current global productionPBEThere are only three major companies:ExxonMobil(VistamaxxTMseries)、Dow(VersifyTMseries)Was Mitsui(TafmerTM XMseries)Three。    

Propylene elastomer(PBE)Propylene is the main raw material,Add a small amount of ethylene(orα-Olefins)A low-crystalline polymer with mainly amorphous regions obtained by solution polymerization of monomers。Different from traditional EPDM,PBEThe ethylene content is usually lower than20%(w),High elasticity、Excellent properties such as high transparency and low temperature toughness,And it has good compatibility with olefin polymers, especially polypropylene,Therefore, it is widely used to improve the optical properties of polyolefins.、Sealing、Hot viscosity、elasticity、Toughness and softness。

PBEIn the downstream consumption structure,AsCPPCast film blending modification,Accounts for most of the consumption,Proportion60%,Secondly, the transparent packaging film field,Its application share23%。in addition,PBEIt is also used in hot melt adhesives and other materials。

(2)Polybutene-1The pilot plant was successfully started up

11moon29day,Tianjin Scientific Experiment Base Polybutene-1The pilot plant successfully completed the entire process,A successful drive。The pilot plant uses the liquid phase bulk olefin polymerization technology independently developed by the Beijing Institute of Chemical Industry,Using self-developed catalysts,Developed series of polybutene-1High-end polyolefin materials,Will continue to expand polybutene-1Product application areas,To achieve independent control of key materials、Provide strong support for improving market competitiveness。

Polybutene-1It is a high-end synthetic new material,Thanks to its creep resistance、Stress crack resistance、Excellent properties such as impact resistance,Polybutene-1Obtained“Plastic Gold”The name。Polybutene-1The application range is very wide,In medical equipment、Industrial buildings、It can be found in food packaging and other fields,Because of its crack-resistant performance,Polybutene-1Mainly used as pipes、Film and packaging。

Polybutene-1The main industrial production process is liquid phase bulk polymerization、Slurry polymerization and gas phase polymerization, etc., The catalytic system for industrial production is mainly Ziegler—Nata(Z-N)Catalytic system,Metallocene catalyst systems have been a research hotspot in recent years.,There is no report on industrial application yet.。

at present,Foreign polybutene-1Manufacturers have3Home,LyondellBasell、 Mitsui Chemicals, Japan and Aikon Corporation of Korea,The current total production capacity is about11.510,000 tons。this3High-quality products produced by the companyPB-1Monopoly position in the market。

(3)High Melt Index Polyethylene

recently,Tianjin Petrochemical successfully produced the first domestically produced polyethylene product with the highest melt indexPE-L H2799D。The melt index of this product is150gram/10More than minutes,Filling the domestic gap,This marks a new breakthrough for Tianjin Petrochemical in the high-end and differentiated development of polyolefin products.。

Melt index is related to polyethylene processing performance、Mechanical properties and product uses。The high melt index polyethylene product produced this time has high fluidity、High gloss、Excellent dispersibility、Excellent processing performance,Can be used for industrial wax making、High-end emerging fields such as resin viscosity reduction and sealing,But the production is difficult。

(4)Multifunctional solution polymerization pilot plant opens up the entire process

11moon16day6hour ,The multifunctional solution polymerization pilot plant at the Tianjin Scientific Experimental Base of Sinopec Beijing Research Institute of Chemical Industry has completed the entire process,One-time driving success!The multifunctional solution polymerization pilot plant adopts the solution polymerization technology independently developed by Beijing Institute of Chemical Technology,Using self-developed catalysts,Preparation of a series of new vinyl elastomer products。

(5)China's first bio-based polypropylene is launched
