What should you know about Polypropylene material? Get it from Petron Thermoplast


Polypropylene is a thermoplastic polymer that is made from combined propylene monomers. It is an additional polymer that has a variety of uses. From packaging for consumer products to automotive industries, it is used in different industries for various purposes. 

Here Petron Thermolast will provide you with some guidelines about polypropylene material.



Scientists from Phillips Petroleum named Paul Hogan and Robert Banks and researchers Natta and Rehn from Germany and Italy were the first to polymerize Polypropylene in 1951. It rose to prominence quickly because commercial production started three years after Italian chemist Professor Giulio Natta polymerized it.

In 1954, Natta invented the first polypropylene resin in Spain and improved its synthesis. The material’s capacity to crystallize aroused great interest. By 1957, substantial commercial production had started in Europe due to its explosive popularity. It is currently one of the polymers that are most frequently made worldwide.


Current Scenario

Some sources claim that worldwide demand for the material generates an overall market of roughly 45 million metric tons. Demand will likely increase to about 62 million metric tons by 2020. The packaging sector uses about 30% of the entire Polypropylene and is the main end user. It is followed by the manufacturing of electrical and equipment, which uses about 13% of the material each. Construction materials take up 5% of the market, followed by the industries that consume 10% each: household appliances and automobiles. The remainder of the world’s usage of Polypropylene is made up of various other applications.


Is there something that you need to be worried about?

In low rolling resistance applications like gears or as a contact point for furniture, Polypropylene’s comparatively slippery surface makes it a potential replacement for plastics like Acetal.

Polypropylene has a relatively high friction coefficient despite being a molecularly slippery material; therefore, Acetal, nylon, or PTFE would be preferred. The low density of Polypropylene, compared to other popular polymers, results in weight savings for producers and sellers of injection-molded polypropylene parts.


Why do people prefer to use it?

It possesses great resistance to organic solvents like lipids at room temperature, but at higher temperatures, it is vulnerable to oxidation (a potential issue during injection molding).

One of Polypropylene’s key advantages is that it may be produced into a live hinge using CNC, injection molding, thermoforming, or crimping. Plastic living hinges are made of incredibly thin parts that can bend without breaking (even over great ranges of motion nearing 360 degrees). The lid on a random bottle of ketchup or shampoo is a good example of a non-load-bearing use where they are incredibly handy. They could be more beneficial for structural applications like supporting a hefty door. Polypropylene is particularly well-suited for living hinges since it resists breaking even when bent repeatedly.


Key Benefits

In addition, Polypropylene may be CNC-machined to contain a living hinge, which speeds up prototype development and is less expensive than alternative prototyping techniques. Creative mechanisms’ capacity to produce living hinges from a single piece of Polypropylene makes us unique.

Polypropylene is more easily copolymerized with other polymers, such as polyethylene, to create composite plastics. Due to the material’s significant changes in characteristics, more durable engineering applications are conceivable thanks to copolymerization than pure Polypropylene.


Explore the characteristics

Here Petron Thermoplast will explain to you what are the prime characteristics of polypropylene material. 

  • Polypropylene doesn’t react easily with diluted bases and acids, making it an ideal choice for containers of such liquids, including cleaning solutions, first-aid supplies, and more.
  • Toughness: Polypropylene, like all materials, exhibits elasticity throughout a particular deflection range, but it also exhibits plastic deformation early in the deformation process, making it a “tough” material. Engineers use the term “toughness” to describe a material’s capacity to deform (plastically, not elastically) without breaking.

Resistance: Despite extensive twisting, bending, and flexing, Polypropylene maintains its shape. Making living hinges is a particularly valuable application of this characteristic.

Insulation: Polypropylene has a very strong resistance to electricity and is highly beneficial for electronic components.

Although it can be made transparent, Polypropylene is typically produced with a naturally opaque color. Applications, where some light transfer is crucial or has aesthetic value might be made using Polypropylene. The preferable options for polymers with high transmissivity are acrylic and polycarbonate.

The fact that thermoplastics may be heated to their melting point, cooled, and then reheated repeatedly without noticeably degrading them is a crucially useful property. Thermoplastics, such as Polypropylene, liquefy rather than burning, making it simple to injection mold them and then recycle the resulting material.
