Pp non-woven fabric use, what is the raw material of pp non-woven fabric
PP (polypropylene), a Chinese name for polypropylene, is a polymer obtained by free radical polymerization of propylene monomer. It has a non-toxic, odorless, odorless, milky white high crystalline shape and is a crystalline material. At present, there are many varieties of polypropylene resins produced in China, such as flat-grade polypropylene, biaxially oriented polypropylene special resin (BOPP special material), injection-grade polypropylene and ethylene propylene poly-polypropylene.
Characteristics of polypropylene (PP)
Polypropylene resin is the lowest density in general-purpose plastics, has good mechanical properties, good rigidity, good wear resistance, high hardness, good heat resistance, poor cold resistance, no water absorption, good chemical stability, but not resistant to sunlight. Poor thermal stability; flammable, oily smell when burning; good electrical insulation, voltage resistance, transparent film, poor penetration of air and water vapor; good for forming film, silk and other products, but dyeing, printing , poor adhesion.
Polypropylene (PP) plastic products use
First, the film. Mainly used for the packaging of various foods, industrial products, daily necessities and electrical components.
Second, hollow products. Used in a variety of liquid fuels, chemical liquids and household chemicals containers.
Third, injection molding products. Used in daily necessities and various mechanical parts.
Fourth, a variety of pipes, plates and sheet products. Mainly used for wire, cable sheathing and thermoforming various tanks.
5. Slings and fibers. It is used for packaging and tying articles and various woven tapes for packaging.
The above is the introduction, characteristics and product use of polypropylene (PP), followed by the composition grade of polypropylene.
The higher the polypropylene material, the better.
In the PP nonwoven fabric, polypropylene (PP) pellets are often used as raw materials. It is produced by high-temperature melting, spinning, steel-plating and hot-pressing coiling in one step. At the same time, more importantly, the products of PP non-woven fabrics are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and elegant, with various patterns and styles, light weight, environmental protection, and can be recycled. Ecological and environmentally friendly products. Applicable to agricultural film, shoemaking, leather, mattress, quilt, decoration, chemical, printing, automotive, building materials, furniture and other industries.
