PRICE OF POLYPROPYLENE

WHAT IS POLYPROPYLENE?
Polypropylene, also known as polypropene, is a versatile thermoplastic polymer that you can use in various applications. For clarification, thermoplastic, often called thermosoft plastic, is any plastic polymer substance that becomes flexible and moldable at high temperatures and hardens at low temperatures. This capability, combined with polypropylene’s capacity to melt rather than burn when subjected to high temperatures, are two essential characteristics that make it a sought-after choice for manufacturing applications.
Among all commercial plastics, this linear hydrocarbon resin is the lightest. Manufacturers can considerably enhance PP with particular additives. But what does polypropylene mean? Polypropylene is a polyolefin that is tougher than polyethylene. It is a low-density, high-heat resistance commodity plastic with the chemical formula C3H6. Industries such as packaging, medical, automotive, consumer goods and cast films typically use PP.
PP can be:
-
- Hard or soft
- Light or heavy
- Opaque or transparent
- Insulating or conductive
- Neat or reinforced with other inexpensive mineral fillers, short or long glass fibers and natural or self-reinforced fibers
TYPES OF POLYPROPYLENE
There are two primary types of polypropylene — homopolymer and copolymer. Depending on its usage, you’ll require a specific kind of polypropylene. Some people call PP the “steel” of the plastic industry due to its adaptability to serve specific purposes, generally by adding particular ingredients or producing them uniquely. Here are the critical differences between the two polypropylene types.

- Polypropylene homopolymer: This type is the most widely used general-purpose PP. When polymerizing a single monomer to produce a macromolecule, a homopolymer forms. A homopolymer consists of repeating units of a single monomer type. Examples of homopolymers include polycaprolactam, polyester and polyethylene.
- Polypropylene copolymer: Polymerizing more than one kind of monomer generates a copolymer. As a result, a copolymer always contains two or more types of repeating units created by a process known as condensation polymerization. Examples of copolymers include ethylene-vinyl acetate, high-impact polystyrene and acrylonitrile butadiene styrene.
Unlike homopolymers, copolymers have further classifications depending on the arrangement of the monomers on the main chain. There are two subtypes of copolymers.
- Polypropylene block copolymer: PP-BC comprises comonomer units organized in a regular pattern and contains 5% to 15% ethylene. Ethylene increases specific qualities, like impact resistance, whereas other additions improve others.
- Polypropylene random copolymer: This subtype goes through the process of polymerizing ethene and propene together. In contrast to PP-BC, the comonomer units in PP-RC occur in irregular or random patterns along the polypropylene molecule. They mix about 1% to 7% ethylene for applications requiring a more flexible, transparent result.
WHAT IS POLYPROPYLENE FOR?
Because of polypropylene’s characteristics, you can apply it in residential and industrial settings. Its adaptability to diverse manufacturing processes and applications distinguishes it as a primary player in the plastic industry. Another significant property is PP’s capacity to behave as a plastic and a fiber. Here are a few polypropylene uses in various industries.
- Product packaging: PP offers outstanding barrier qualities, making it an excellent choice for packaging applications. It provides strength, water resistance and superior surface quality at a low cost. Polypropylene plastic works well when blow-molded or thermoformed to create packaging shapes for items like food, personal care products and medical and laboratory items. Crates, bottles and pots are examples of blow-molded polypropylene plastic for flexible packaging, whereas items like syringes and reusable food containers are examples of thermoformed polypropylene plastic for more rigid packaging.
- Automotive parts: Due to PP’s excellent mechanical and chemical qualities and moldability, the automotive industry relies on it to produce bumpers, battery boxes and trays, instrument panels, fender liners, door trims and other interior elements.
- Fabrics: The fibers and fabrics industry uses a significant amount of PP. Raffia or slit-film, strapping, tape, staple fibers, continuous bulk filament, spun bond and continuous filaments are all applications for PP fiber. PP rope and twine are robust and moisture-resistant, making them ideal for marine applications.
- Medical supplies: PP’s microbiological, chemical and steam sterilization resistance makes it incredibly useful in medical settings. You can find polypropylene in disposable syringes, pill containers, Petri dishes, medical vials, intravenous bottles, diagnostic devices and food trays.
- Cable protection: Polypropylene is a durable solution to protect cables from operational and environmental stresses like water, chemicals, foot traffic and even rodent predation. Examples of PP cable protection include plastic conduits and cable drag chains. Cable protection is crucial because cables are subject to substantial strain during their lives, which causes them to decay. They usually require replacement if they have deteriorated to the point that they can no longer perform their tasks or are hazardous to use.

PROS AND CONS OF POLYPROPYLENE MATERIALS
Because of its durability, flexibility and other advantages, polypropylene is a popular material for the packaging, automotive, medical and fabric industries. Before using it, consider its upsides and downsides.
Advantages
Polypropylene has several advantages that contribute to its popularity among producers who may put it to use in various applications. See below for PP’s primary benefits.
- High tensile strength: Polypropylene has a high tensile strength, which means it can carry about 27 MPa or 4,000 pounds per square inch, making it an excellent material for large loads.
- Flexibility and malleability: When polypropylene reaches its melting point, it can mold into any desired shape numerous times without deteriorating. PP is malleable, which means it may form into a living hinge or a piece of material that can repeatedly bend without breaking.
- Highly water-resistant: Polypropylene absorbs less than 0.01% of its weight when soaked in water. This quality makes it ideal for objects that require waterproofing.
- Good chemical resistance: Because of its chemical qualities, polypropylene doesn’t react with acids, making it perfect for containers designed to retain acidic solutions such as cleaning chemicals. Since it is also resistant to corrosion and chemical leakage, it’s excellent for pipe systems.
- Excellent electrical insulator: Polypropylene doesn’t conduct electricity effectively. As a result, it’s a leading choice for insulating electrical components such as cables and audio equipment.
Disadvantages
Like any manufactured material, propylene has various downsides that consumers and producers should be aware of before using it.
- High thermal expansion coefficient: Polypropylene has a limit to its high-temperature applications, as a high thermal expansion coefficient means that the material will expand when heated. Thermal expansion is a material’s tendency to alter size, shape and volume as its temperature rises.
- Susceptible to UV degradation: Polypropylene is unsuitable for usage at high altitudes or in areas with strong UV penetration, as it’s vulnerable to UV degradation.
- Poor bonding properties: Polypropylene has poor bonding characteristics, making it challenging to paint.
- Highly flammable: Polypropylene is combustible and will quickly melt when heated. Its flashpoint is only 260 degrees Celsius.
- Prone to oxidation: Polypropylene has restricted usage in high temperatures due to chain breakdown, which can result in oxidation — causing cracks in the PP.
