The raw material of pp non-woven fabric is what

In the production of non-woven, people commonly used polypropylene ( PP) Do non-woven raw materials. The polypropylene ( PP) And new grain, powder, back to the material and add calcium powder. Affect the price of non-woven production using different materials, so, what is polypropylene ( PP) ？ A new aggregate, powder, what is the difference between back material, adding calcium powder? Below small make up a simple introduction for you. Polypropylene ( PP) 页( 聚丙烯) , the Chinese name of polypropylene, is a kind of composed of acrylic monomers by free radical polymerization of polymers, with non-toxic, odourless, tasteless milk white crystal shape, high belongs to crystalline materials. Variety is more, the current domestic production of polypropylene resin production batch is large flat wire grade polypropylene, two-way stretch polypropylene resin ( BOPP special materials) , injection molding grade polypropylene and ethylene propylene polyethylene polypropylene, etc. Polypropylene ( PP) Properties of polypropylene resin is the lowest common plastic medium density, good mechanical properties, rigidity, good wear resistance, hardness is higher; Has good heat resistance, cold resistance is poor; Not bibulous, chemistry stability is good, but not resistant to sunlight, poor thermal stability; Flammable, burning oil smell out; Good electrical insulation, resistance to voltage, transparent film, the air and water vapor permeability is poor; For better forming film, wire and other products, but poor dyeing, printing, binding. Polypropylene ( PP) Plastic products use a, film. Mainly used in all kinds of food, industrial packaging products, daily necessities of life, and electrical components. Second, the insulating products. Used to do all kinds of liquid fuel, chemical industry and daily chemicals containers. Three, injection molding products. Used for daily necessities of life and all kinds of mechanical parts. Four, all kinds of pipe, plate and sheet products. Mainly used for wire, cable sheath and thermoforming of groove type, etc. Five, the sling and fiber. Used to wrap a knot packaging and all kinds of weave belt, etc. The above is polypropylene ( PP) Introduction, characteristics and USES of products, the next was among the polypropylene composition level. 1, 2, powder 3 new aggregate, back up 4, adding calcium powder, polypropylene material, the better. In PP non-woven fabric, use polypropylene (more PP) Grain as raw materials. By high temperature melting, spinning, steel, heat the top ranking paper for one-step production. At the same time, more important is the PP non-woven products rich colors, bright and lively, fashion, environmental protection, widely used, beautiful and easy, designs and styles are diverse, and qualitative light, environmental protection, can be recycled to use, is internationally recognized for protection of the earth's ecological environmental protection product. Suitable for agricultural film, footwear, leather, mattresses, lash, decoration, chemical industry, printing, automotive, building materials, furniture and other industries, etc.
