Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant.
PP retains mechanical & electrical properties at elevated temperatures. This occurs in humid conditions and when submerged in water. It is a water-repellent plastic. PP has good resistance to environmental stress cracking. It is sensitive to microbial attacks, such as bacteria and mold. It exhibits good resistance to steam sterilization.
Isotactic polypropylene is produced at low temperatures and pressures, using Ziegler-Natta catalysts.The polymer shares some of the properties of polyethylene, but it is stronger, stiffer, and harder, and it softens at higher temperatures.(Its melting point is approximately 170 °C [340 °F].) It is slightly more prone to oxidation than polyethylene unless appropriate stabilizers and ...
What is Polypropylene (PP)? Polypropylene is a thermoplastic polymer, belonging to the polyolefin family of polymers. It is produced through the polymerization of propylene monomers and is characterized by its light weight, high strength, chemical resistance, and good heat resistance. Polypropylene (PP) appears as white granules, odorless and non-toxic. Its molecular structure is similar to […]
Polypropylene (PP) is a remarkable thermoplastic material that has gained widespread popularity in various industries due to its exceptional properties and versatility. With its low density, high chemical resistance, and excellent balance of strength and flexibility, PP has become a go-to choice for numerous applications ranging from packaging ...
The Harmonized System (HS) Code for Polypropylene (PP) is 39021000.. Polypropylene (PP) is characterized by its relatively low density, typically ranging between 0.89 to 0.91 grams per cubic centimeter (g/cm³). Polypropylene (PP) is known for its relatively high melting point.The melting point of polypropylene typically ranges between 160 to 166 degrees Celsius (320 to 331 degrees Fahrenheit).
Polypropylene is a type of thermoplastic polymer resin.It is a part of both the average household and is in commercial and industrial applications. The chemical designation is C3H6.
Polypropylene (PP) is a low-density, stress-resistant thermoplastic made from a propene (or propylene) monomer. The chemical formula for this linear hydrocarbon resin is (C3H6)n. It was discovered in the mid-1950s by Italian scientists and is today the second most manufactured plastic after polyethylene.
PP is 100% recyclable. Automobile battery cases, signal lights, battery cables, brooms, brushes, and ice scrapers are a few examples of products which can be made from recycled polypropylene (rPP).
PP is an abbreviation that can stand for 239 different meanings, such as Profile Picture, Papua New Guinea, PowerPoint, PayPal, and more. See the full list of definitions and categories of PP on AcronymFinder.
