POLYPROPYLENE (PP)

 

DESCRIPTION

Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
In 2013, the global market for polypropylene was about 55 million metric tons.

 

APPLICATIONS

Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Polypropylene is normally tough and flexible, especially when copolymerized with ethylene. This allows polypropylene to be used as an engineering plastic, competing with materials such as acrylonitrile butadiene styrene (ABS).
Polypropylene is reasonably economical, and can be made translucent when uncolored but is not as readily made transparent as polystyrene, acrylic, or certain other plastics. It is often opaque or colored using pigments. Polypropylene has good resistance to fatigue. The melting point of polypropylene occurs at a range, so a melting point is determined by finding the highest temperature of a differential scanning calorimetry chart.

DESCRIPTION

Homopolymers are random copolymers and impact copolymers that offer optimum performance for customer injection molding, blow molding, film, fiber, sheet extrusion and thermoforming applications.

 

APPLICATIONS

Polypropylene is used in automotive parts, such as battery cases, fascia, running boards and bumpers. It is also used in housewares, appliances, grid-type flooring for sports facilities, tackle boxes, wood-plastic composites for decking, bottles and bottle profiles; and caps and closures.

DESCRIPTION

Polypropylene (PP) impact copolymers are thermoplastic resins produced through the polymerization of propylene. Copolymers are created by introducing a heterophasic structure inside a semi-crystalline PP homopolymer matrix.
Polypropylene is one of the world’s most versatile plastic materials. With its broad range of properties, the material is used to produce everything from packaging and housewares to automotive and electrical applications.

 

APPLICATIONS

  • Thick extrusion
  • Pipe
  • Film
  • Thermoforming
  • Injection molding (caps & closures, batteries, pails, automotive, TWIM)

PROPERTIES

  • Good impact performance at low temperatures
  • Good stiffness performance at low temperatures
  • Good aesthetic characteristics
  • Good creep resistance
