Dec 25, 2021


Polypropylene (PP)


PP (polypropylene), called polypropylene in Chinese, is a polymer formed by free radical polymerization of propylene monomer. 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 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 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, smells 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. Webbing 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 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 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 diverse in patterns and styles, and are light, environmentally friendly, and recyclable. They are recognized internationally to protect 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.
