What is polypropylene drawing material

It can be seen literally that the main raw material of polypropylene drawing material is polypropylene. Polypropylene is the world's lightest thermoplastic resin. Its main upstream raw materials are petroleum, coal, etc., which can be divided into copolymer polypropylene and polypropylene according to the content of ethylene. Homopolymer polypropylene has excellent electrochemical properties and excellent bending resistance, and is widely used in packaging and small household appliances. Polypropylene wire drawing material is to dry and stir polypropylene, release it to dissipate heat when the temperature is set, and then put it in the hopper of the extruder. The polypropylene enters the screw groove of the hopper and is forced to the machine head. After a period of time, the polypropylene is extruded, and the viscous polypropylene film is immediately entered into the cooling water tank for rapid cooling and shaping into a film, after the slitting rack cutting process, and then heated by two sets of baking hot plates After processing, the wire is wound in sequence on the winding unit, so that the polypropylene drawing material is formed. Generally speaking, polypropylene wire drawing material is mainly used in the plastic woven industry. It has excellent corrosion resistance, non-water absorption and tensile properties. Therefore, it is particularly suitable for packaging bags such as container bags, snakeskin bags, and heavy industrial cement. For polyethylene packaging bag products, polyethylene has stronger rigidity and longer service life, and its reusable nature is more in line with the needs of current green life. Over the years, polypropylene wire drawing materials have accounted for a relatively large proportion of plastic products. According to statistics, the production of flat yarns and woven products in 2017 consumed about 13.5 million tons of polypropylene, accounting for 43% of the total consumption of polypropylene. In recent years, China’s real estate cement, sand Such as heavy industry packaging demand growth and the demand for bulk commodity grains and fruits accelerated, and the output of polypropylene drawing materials has risen rapidly. At present, the domestic polypropylene drawing materials market is basically saturated, but the market for special materials is still large. From the perspective of import data, 70% of imported products are special materials.
