Polypropylene and its diverse applications | Anzen Exports

October 27, 2022by Anzen_Exports0

Polypropylene is a popular thermoplastic polymer, a synthetic resin produced by polymerising propylene. Due to its durability, flexibility, lightweight and resistance to heat, it is moulded into various plastic goods and spun into fibres.

Polypropylene and its diverse applications

Physical and chemical characteristics

Polypropylene (PP) is a polymer, basically, and its monomer is propylene. It is produced by a polymerisation or chain growth reaction. The polymer softens on heating and thus can be remoulded. Being similar to polyethylene in many ways, PP is more heat resistant and harder. PP exists as a white-coloured solid under conditions of standard temperature and pressure. Other physical and chemical characteristics of PP are:

  • The density of PP is in the range of 0.89 to 0.92 grams per cubic centimetre.
  • It is a thermoplastic polymer, very tough and heat resistant.
  • It is remarkably flexible.
  • The PP is resistant to organic solvents
  • It is resistant to weak oxidising agents
  • It is soluble in organic solvents such as xylene
  • It is chemically resistant towards water, alkalis and acids
  • PP may exist in three primary types: block polymer, homopolymer and random polymer.

Polypropylene and its diverse applications

Applications of Polypropylene 

PP has wide usage in applications due to its characteristics as a chemical compound. These are:

  • With a high melting point, PP finds usage in manufacturing microwave-friendly containers.
  • It is highly flexible and quite resistant to stress and cracking; hence it is used in hinges construction.
  • The polymer is used to manufacture plastic living hinges, especially on containers and bottle covers, as it is highly durable and resistant to wear and tear.
  • Plastic piping is made from PP because it is robust, sturdy, and resistant to corrosion and chemical leaching.
  • PP can resist high temperatures in autoclaves, which manufacture plastic laboratories and medical items.
  • For the characteristics mentioned above, it finds usage in manufacturing mats, rugs, carpets, ropes, storage boxes, stationery folders and packaging items.
  • It is used to manufacture loudspeaker drive units as it is a thermoplastic.
  • It is observed that PP is suitable for manufacturing packaging material due to its low cost, good surface finish, high strength and flexible characteristics.
  • PP is thus used to blow and mould to manufacture bottles, crates and pots. Thin films of PP are used for food packaging.
  • PP may also find use in manufacturing toys, household items, furniture and luggage.
