What Is PP Plastic (Polypropylene)? Is It Toxic? Properties And Diverse Applications Of PP Plastic In Life

Bởi Son Vu

PP plastic is a synthetic polymer widely used in many areas of life. Thanks to superior properties such as high durability, water resistance, good heat resistance, PP has become an indispensable material in the production of a variety of products. So what is PP plastic? Is it toxic? And what properties make PP plastic popular and widely used in everyday life? Let's learn details about PP plastic with EQUO in this article!

1. Overview of PP plastic

PP plastic is one of the most popular and versatile plastics on the market today. With special properties and outstanding advantages, PP plastic has been widely applied in many different areas of daily life, from production to consumer life.

1.1. Definition of PP plastic

PP plastic, or Polypropylene, is a widely used polymer found in various everyday items. Renowned for its durability, hardness, heat resistance, and corrosion resistance, PP plastic is among the most favored plastics globally.

1.2. Properties of PP plastic

PP plastic has the following properties:

  • High hardness and durability.
  • Has relatively high heat resistance (more than 100 degrees Celsius).
  • Has high elasticity and bendability.
  • Resistant to water vapor, grease, and gases.
  • Able to recover after impact.

1.3. Is PP plastic toxic?

While PP plastic is often touted as non-toxic and FDA-certified for food contact, it's essential to note that this material isn't without its drawbacks. While it may be chemically inert, meaning it doesn't readily react with other substances to produce toxins, there are still concerns.

Despite its widespread use in everyday items ranging from household appliances to medical products and food packaging, PP plastic isn't entirely free from potential issues. For instance, while it doesn't contain harmful substances like bisphenol A (BPA) or phthalates, it can still leach chemicals under certain conditions, especially when exposed to heat or acidic substances.

Additionally, while PP plastic is technically recyclable, its recycling rate remains relatively low compared to other plastics due to challenges in the recycling process. Its low density also means it can easily float and contribute to marine pollution if not disposed of properly.

Furthermore, while PP plastic may break down over time, it does so very slowly, contributing to environmental pollution in the form of microplastics. Therefore, while PP plastic may have its advantages, it's crucial to consider its limitations and environmental impact when assessing its overall suitability for various applications.

2. How isPP plastic produced?

PP plastic is produced through two main methods:

2.1. Ziegler-Natta polymerization

Raw material: Propene (C3H6)

Catalyst: Ziegler-Natta


  1. Propene is introduced into the reactor along with the Ziegler-Natta catalyst.
  2. Under appropriate temperature and pressure, propene will polymerize to form polypropylene.
  3. The resulting polypropylene is cooled, degassed, and cut into granules.

2.2. Metal-catalyzed polymerization (Metallocene catalysis polymerization)

Raw material: Propene (C3H6)

Catalyst: Metal (such as titanium, zirconium)

Process: Similar to the Ziegler-Natta method, but using a metal catalyst. This method allows for better control of the molecular structure of polypropylene.

3. Advantages and disadvantages of PP plastic

Thanks to outstanding advantages such as high durability, water and chemical resistance, and low price, PP plastic is used in many different fields such as packaging production, household appliances, automobile components, textiles, etc. However, besides the advantages, PP plastic also has some disadvantages that need to be kept in mind when using it.

3.1. Advantages of PP plastic

  • Light: PP plastic has a low density, only 0.91 g/cm³, lighter than many other plastics such as ABS, PS, and PVC.
  • Durable: PP plastic has high mechanical strength, withstands impact well, and does not crack easily.
  • Waterproof: PP plastic has good water resistance and does not deform when exposed to water.
  • Chemical resistance: PP plastic is resistant to many chemicals, acids, and bases.
  • Safe for health: PP plastic is certified by the FDA (US Food and Drug Administration) as safe for health, and can be used to store food and beverages.

3.2. Disadvantages of PP plastic

  • Low heat resistance: PP plastic can only withstand maximum temperatures up to 100°C, and is easily deformed when exposed to high temperatures.
  • Poor fire resistance: PP plastic is easy to catch fire and spreads.
  • Difficult to print: PP plastic has difficulty adhering to ink, so surface treatment is required before printing.
  • Non-biodegradable: The majority of products made from PP plastic from its early days still remain on our planet. They are often challenging to recycle, and most end up discarded in landfills. These plastics can persist here for decades to hundreds of years before breaking down into microplastics, continuing to have a severe impact on health and the environment.

When choosing PP plastic, prioritize products with clear origins and good quality. Although PP plastic has many advantages, at the same time there are still many disadvantages. Plant-based products are still the optimal choice for the environment. If possible, prioritize using plant-based products to best protect the environment.

4. Applications of PP plastic in life

From simple water bottles to colorful children's toys or useful household items, PP plastic penetrates every corner and brings practical conveniences to consumers.

4.1. Water bottles, containers, and food packaging

Producing products such as water bottles, containers, and food packaging using PP plastic is a common application of this plastic. PP plastic is used in the production process as the main raw material because it can create products that are durable, waterproof, and easy to reuse. PP plastic products are designed and manufactured using advanced technological processes to meet a variety of market needs, from convenient daily water bottles to high-quality food containers and packaging.

Nevertheless, the lifecycle of PP plastic products raises concerns among consumers, especially considering their near non-biodegradability. The use of PP plastic products, particularly single-use items, exacerbates plastic pollution and impacts the environment.

As a result, many consumers believe that products sourced from natural materials, free from plastic and capable of biodegradation, will be safer for both health and the environment compared to synthetic products. These products are seen as the most sustainable and preferable alternatives to plastic-based products.
