In the production of non-woven fabrics, people often use polypropylene (PP) as the raw material for non-woven fabrics. And polypropylene (PP) is divided into new pellets, powder, regrind and calcium powder. The production of different raw materials affects the price of non-woven fabrics. So, what is polypropylene (PP)? What is the difference between the new pellets, powder, regrind, and calcium powder? Here is a brief introduction for everyone.
Polypropylene (PP)
PP (polypropylene), called polypropylene in Chinese, is a polymer formed by free radical polymerization of propylene monomers. It has a non-toxic, odorless, and tasteless milky white highly crystalline shape. It is a crystalline material . At present, there are many varieties of polypropylene resins produced in China. The production batches are relatively large flat yarn grade polypropylene, biaxially oriented polypropylene special resin (BOPP special material), injection grade polypropylene and ethylene propylene copolymer polypropylene.
Characteristics of Polypropylene (PP)
Polypropylene resin has the lowest density among general-purpose plastics. It has good mechanical properties, good rigidity, abrasion resistance, and high hardness; it has good heat resistance and poor cold resistance; it does not absorb water and has good chemical stability. Sunlight resistance, poor thermal stability; flammable, smell of oil when burned; good electrical insulation, voltage resistance, transparent film, poor permeability to air and water vapor; good for forming films, silk and other products, but Dyeing, printing, and adhesion are poor.
Polypropylene (PP) plastic products use
1. Film. Mainly used for packaging various food, industrial products, daily necessities and electrical components.
2. Hollow products. Used to make containers for various liquid fuels, chemical liquids and daily chemicals.
3. Injection molding products. Used in daily necessities and various mechanical parts.
4. All kinds of pipes, plates and sheet products. Mainly used for wire, cable sheath and thermoforming various grooves, etc.
Five, flat belt and fiber. Used for packaging bundling items and various packaging woven tapes, etc.
The above is the introduction, characteristics and product uses of polypropylene (PP), followed by the composition level of polypropylene.
1. Brand new pellets
2. Powder
3. Material return
4. Add calcium powder
The higher the position, the better the polypropylene material.
In PP non-woven fabrics, polypropylene (PP) pellets are mostly used as raw materials. It is produced by continuous one-step method of high-temperature melting, spinning, steel laying, and hot-pressing coiling. At the same time, the more important point is that the products of PP non-woven fabrics are rich in color, bright and lively, fashionable and environmentally friendly, versatile, beautiful and generous, patterns and styles are diverse, and light, environmentally friendly, and recyclable. They are internationally recognized as protecting the earth Eco-friendly products. It is suitable for agricultural film, shoemaking, tanning, mattresses, quilt, decoration, chemical, printing, automobile, building materials, furniture and other industries.
