Polypropylene PP

  • Abbreviation: PP Resin
  • Appearance: White  granules
  • Density: 0.89~0.91g/cm³
  • CAS No.: 9003-07-0
  • HS Code: 39021000
  • Molecular Formula: (C3H6)n

Polypropylene resin is colorless cylindrical particles, non-toxic, tasteless, and its density is 0.90-0.91g/cm3. PP is relatively hard in nature and has the characteristics of good elongation, electrical insulation, good chemical stability, and good processing performance. Therefore, polypropylene PP resin can be widely used in the production of fiber products such as clothing and blankets, medical equipment, automobiles, bicycles, parts, pipes, chemical containers, etc., as well as food and drug packaging.

Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing performance, etc. At present, PP resin particles have become one of the synthetic resins with the fastest development speed, the largest output, the most brands, the widest application, and the rapid growth in consumption.

  • High rigidity and low density (0.90—0.91), high tensile strength (especially after stretching), excellent transparency, stress crack resistance, chemical resistance, high heat resistance, The melting point reaches 164 degrees, and it can be used for a long time below 100-120 degrees. It has good electrical insulation and good folding resistance.
  • After being filled and reinforced, the mechanical properties of polypropylene are sufficient to compete with higher-cost engineering plastics in many applications.
  • Good injection molding processability.
  • It can be stretched and oriented to produce fibers and stretched films.
  • The disadvantage is that it is easy to be brittle at low temperature, insufficient wear resistance, poor aging resistance, not easy to dye, and large molding shrinkage.

From the polymerization method, PP resin is divided into homopolypropylene and copolymerized polypropylene (block copolymer, random copolymer). Besides, PP homopolymer can be divided into: drawing grade, injection molding grade, film grade and fiber grade.

According to its crystallinity, polypropylene can be divided into isotactic polypropylene and atactic polypropylene and syndiotactic polypropylene. Usually, we have more contact with isotactic polypropylene.

Main Applications of Polypropylene PP Resin​​

Polypropylene resin can be formed by injection, extrusion, blow molding, lamination, melt spinning and other processes, and can also be biaxially stretched. Therefore, PP resin is widely used in the manufacture of containers, pipes, packaging materials, films and fibers, and is also commonly used to obtain engineering plastics with excellent performance through reinforcement methods. In addition, PP granules is also used in automobiles, construction, chemicals, medical appliances, agriculture and household products.

  1. Film products. PP film products have good transparency and luster, and the permeability of water vapor and air is very small. According to different processing techniques, they can be divided into blown film, salivating film (cpp), and biaxially oriented film (BOPP).
  2. Injection molded products. PP granules can be used for engineering accessories such as automobiles, electrical appliances, machinery, instruments, radios, textiles, and national defense, daily necessities, turnover items, medical and health equipment, and building materials.
  3. Extruded products. It can be used as pipes, profiles, wire drawing, fishing ropes, packing belts, binding ropes, woven bags, fibers, composite coatings, sheets, plates, etc. Blow molding hollow molding products, various small containers, etc.
  4. Others. Thermoforming, foaming, high foaming can be used as structural foam, synthetic wood, laminated board, synthetic paper.
