Polypropylene copolymer, mixture

Through optimizing design to reduce investment and operation costs will continue to give priority of polypropylene industry development. Polypropylene main improvements to reduce costs is: 1. Through the use of highly active catalyst to improve the yield. 2. To reduce the total cost of the device, such as layout optimization process, reduce the prime cost item. Copolymerization technology developing rapidly, and the copolymer is the development of polypropylene impact copolymer markets and applications, one of the important driver of growth in recent years the rapid growth of polypropylene resin should be mainly attributed to the development of polypropylene copolymer and blend. Polypropylene copolymer alternative and develop a new market, particularly in the field of processing and injection molding and blow molding, film field.

in nearly 4 - Five years to the development of the alum with synthetic single-site catalyst is relatively simple, high yield, and is helpful to reduce the cost of catalyst, can produce a variety of the characteristics of polyolefin products in the century is expected to become another development focus in the catalysts for olefin polymerization, with traditional ziegler catalyst and metallocene catalyst to promote the development of polypropylene industry. A single-site catalyst and metallocene catalyst of alum have similarities, can according to need to customize the polymer chain, at present this kind of catalyst system is still in the early stages of development.

due to the blending polypropylene easily with a variety of other materials or alloying, in recent years, various dosage of polypropylene blend/alloy products continue to increase. Blend and alloying widen the performance of the polypropylene product range, can make it in a wider range of applications is tailored according to the requirements of customers meet the performance requirements of the product. With polypropylene market competition intensifies, some of the world's largest companies pay more attention to/pp blend alloy product development and development.

polypropylene impact copolymer is mainly used in automotive, consumer products, appliances and packaging, and office furniture, integrated with the polypropylene impact copolymer for rigid/impact resistance performance, thermal deformation temperature, better gloss, will make polypropylene in the market further instead of ABS resin, polystyrene and high density polyethylene and other plastic.

metallocene catalysts in the field of application in the field of polypropylene behind the polyethylene, look from the current market, with a very small proportion of metallocene catalyst in the production of polypropylene products, application scope is narrow. In the future, with the increase of global development alliance, metallocene polypropylene products will accelerate the pace of development, to some common injection molding processing products market development.

using the law of boron compound as activator of metallocene catalyst system, don't have to use expensive alumina alkanes and aromatic drill compound, using amino benzene copolymer resin as the carrier of metallocene catalyst. Polypropylene production device to continue to develop in the direction of large-scale, in the late 1990 s as a group of large plant put into production and the original plant of removing bottlenecks, several main average size of polypropylene technology has reached more than 200000 tons/year.
