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 and is a crystalline material. At present, there are many varieties of polypropylene resin produced in China, and the production of relatively large batches of flat fiber grade polypropylene, biaxially oriented polypropylene special resin (BOPP special material), injection grade polypropylene and ethylene-propylene copolymer polypropylene, etc.

 

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 a good heat resistance and poor cold resistance; it does not absorb water and has good chemical stability, but it is not resistant to sunlight. Poor thermal stability; flammable, the smell of oil when burned; good electrical insulation, voltage resistance, transparent film, poor penetration of air and water vapor; good for forming films, silk, and other products, but dyeing and printing, Poor adhesion.

 

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.

 

5. Flat belt and fiber. Used for packaging bundling items and various packaging woven tapes, etc.

 

The above is the introduction, characteristics and product use of polypropylene (PP), followed by the grades of ingredients in polypropylene.

 

New pellets, powder, regrind, plus 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 a 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 industry, printing, automobile, building materials, furniture, and other industries.
