When using PP extruded profiles, processing performance is always better, low velocity profile extrusion is usually limited to a smaller section water to quench guarantee products have enough toughness.
PP coating online also has a purpose.
In terms of dosage after extrusion molding processing is to adapt to the characteristics of polypropylene.
PP good flow property and strong mechanical properties, is used to produce many different types of has intrinsic strength and mechanical properties of the product.
homopolymer resin are usually classified according to the flow velocity and purposes. Velocity depends on both the average molecular weight and molecular weight distribution. Some special use requirements flow rate as high as 400 g/min, and ordinary commodity homopolymerization logistics at zero speed. 5 - Within the range of 50 grams/minute. Velocity is usually determine the machining features are the main factors.
extruded products is the biggest market of consumption of PP, the textile fiber and filament is one of the biggest part. For a long time, the main raw material of PP has been manufactured fiber. It is because his tinting strength, wear resistance, chemical resistance, and favorable economic conditions. Orientation and the film's second big extruded products market, and is to continue to keep growth areas.
article contains the adornment of the foaming agent with the product is made of polypropylene extrusion velocity is close to 10, so that the melt strength and orientation ability to achieve the appropriate balance, orientation of the polymer via moderate, can produce a smooth surface like satin on effect, the product has enough transverse strength can delay fracture. The weaving and squeeze more silk product needs a low viscosity, the free flow of material, so the high velocity of polypropylene used for these purposes.
pouring PP film in the drawing art, in addition, the film can be biaxial orientation and thermal alteration, has excellent mechanical properties and thermal properties, applied to various performance laminated materials and packaging materials. Using tubular water-cooled excitation technology can put the PP processed into a total of extrusion blown film and single-layer film. Hot molding with extruded sheet requires the use of low velocity formula of material, make have enough melt strength.
polypropylene good flow property and wide range of flow rate, and other unique characteristics of polymer, the combination of his excellent performance of injection molding processing, can satisfy the extrusion with low velocity, ribbon filament and monofilament processing requirement, also can make the finished product has low tensile strength and extensibility, while maintaining enough lateral integrity, make the split on the thread rolling machine guide and dust to a minimum. In order to offset their own low transverse strength and the fracture tendency, orientation degree higher film to fibre products.
good processability and excellent resistance to stress cracking performance produced excellent molded seal cover. Generally speaking, the low velocity formula materials used in the production of wall thickness products and the toughness of the products. High velocity of the material for the production of thin wall parts and rapid processing of products. PP homopolymer can use all kinds of processing technology, production of a wide range of products.
plastic processing products is the second largest market of PP homopolymer, including container and seal pot, auto, household goods, toys, and many other consumer and industrial aspects of the end use. Many choose polypropylene blow molding containers, because of his good moist insulation performance and enough brew, given the new demand for plastic products in the future, PP homopolymer will continue to grow. Good economic conditions, good mechanical properties and light weight, strong tinting strength and easy processing features, will continue to depend on the PP as material of choice for many applications in the future.
