Description

Poly Propylene (PP) Jam

Poly Propylene (PP) Jam molecule is very similar to the polyethylene molecule, but it also has minor differences. The most popular commercial type of polypropylene is its isotactic type. To produce this polymer, when polymerizing the material and reaching this regular arrangement, it is necessary to Catalyst. Differences between heavy polyethylene and polypropylene are important aspects that make them different in their applications. PP is tighter than PE. As a result, PE materials are used in cases requiring more flexibility (like wrapping).

When the product needs more stiffness or requires more abrasion (such as gears, toys, car batteries, and car seats, use PPs).

Poly Propylene (PP) Jam properties

One of the major properties of PP that has contributed to the growth of this product:

  • High rigidity, low density, high tensile strength, good transparency, resistance to environmental stress (ESCR), chemical resistance and high-temperature resistance (melting point 170 ° C)
  • Having good mechanical strength properties in filler and reinforcement materials.  Also, for many applications, this mixture can compete with expensive engineering polymers.
  • Good molding properties

Poly Propylene (PP) Jam applications

  • Fibers and strings made from PP such as rope, woven textiles, curtain fabrics, sanitary wraps, bags and bandages, car interior fabric
  • Oriented and nondirectional films in packaging, production of pressure sensitive adhesive bands, electric appliances and shrink films
  • Reservoirs and PP containers produced by the infusion process
  • Application in injection moldings, such as all kinds of automotive parts, packaging containers, household appliances, covers, covers, furniture and toys

**Different types of polypropylene include homopolymer and copolymers are different  in their application.

homopolymer are more rigorous and more resistant to copolymers at high temperatures. But the impact strength of the homopolymer at a temperature below zero is very limited.

Copolymers are divided into two random copolymers and Block copolymers. As a result, The difference between the two is in the structure and polymeric chains of Athas and their applications are different.**
