Virgin Raffia Grade Polypropylene
Product description:
Due to the large gap between the supply and demand of polypropylene in my country, in recent years, most new large-scale oil refining, ethylene co-production projects and coal olefin projects have been equipped with polypropylene plants. Therefore, China's polypropylene production capacity will increase substantially in the future. At the same time, it is also necessary to consider those small backward polypropylene installation technologies, especially intermittent small-body method devices, which will be phased out. It is estimated that the production capacity of polypropylene in my country will reach a higher level by 2025. With the rapid development of China's economy, the increasing demand for various chemical raw materials has caused the consumption of polypropylene to reach the highest level ever. Therefore, my country will become the world's largest consumer of polypropylene. In 2003, the consumption of polypropylene in my country has reached 5.32 million tons; in 2007, it was the first to reach 10 million tons; affected by the financial crisis in 2008, it dropped slightly to 10.79 million tons; in 2018, driven by infrastructure investment and domestic demand , Increased to 12.32 million tons.
Polypropylene is non-toxic and tasteless, has low density, strength, rigidity, hardness and heat resistance better than low-pressure polyethylene, and can be used at about 100 degrees Celsius. Has good electrical properties and high-frequency insulation is not affected by humidity. Common grades are homopolymerization, copolymerization and CPP film. Homopolymer is abbreviated as PPH, which is a polymer of single propylene monomer. It has a wide range of applications in the field of thermoplastics, especially in fiber and filament, film extrusion, injection molding and so on. Copolymerization is a copolymer of propylene monomer and ethylene monomer. According to the distribution of ethylene monomer on the molecular chain, copolymerized PP can be divided into two types: random copolymer (PPR) and block copolymer (PPB). Cast film is a kind of non-stretched, non-oriented flat extrusion film produced by solution salivation and quenching. It does not go through the two processes of longitudinal stretching and transverse stretching in BOPP, and directly salivates into the product width.
Except PP Resin,we can also supply Pvc Resin, Pet Resin, Dioctyl Phthalate DOP 99.5%, Carbon Black Pigment, Titanium Dioxide Rutile,Optical Brightener OB1,Iron Oxide Pigments etc.
