Performance Analysis Of Polypropylene Bags
Oct 20, 2017

White, tasteless, odorless inert substances, can be melting at 104-130 degrees Celsius, can also be dissolved in high temperature solvent and resin, but will still precipitate in the cooling, her precipitation fineness and cooling rate: slow Rapid cooling to obtain coarse particles (5-10u), rapid cooling precipitation of fine particles (1.5-3u).Polypropylene Bags 

During the film formation process of the powder coating, when the coating film is cooled, the polyethylene wax is precipitated from the coating liquid to form fine particles, floats on the surface of the coating film, acts as a texture, extinction, slip, and scratch resistance; Selection of wax powder and coating system can be a variety of patterns.Polypropylene Bags

Polypropylene is our daily life is closely related to the common resin, propylene is the most important downstream products, the world's propylene 50%, 65% of China's propylene are used to make polypropylene. Polypropylene is the world's fastest growing general-purpose thermoplastic resin, the total is only second only to polyethylene and polyvinyl chloride.

As with other general-purpose resins, the Asian financial crisis has a significant impact on polypropylene demand, and even at the lower forecast level, polypropylene remains at a relatively strong rate of growth compared to other resins. New forecasts show that the world average demand for polypropylene is 7.1% between 1997 and 2002, compared with 5.2% for the same period, 5.0% for PVC and 4.1% for polystyrene.Polypropylene Bags

The reasons for the rapid growth in demand for polypropylene can be summarized as follows: cheap, light, good processability and wide use, and the development of catalysts and new processes further promotes the expansion of applications such as automotive and food packaging Of the development further contributed to the growth of demand, in the past not so much polypropylene for the automotive industry, in the past, polypropylene is also rarely used for blow molding and thermoforming.Polypropylene Bags
