PP plastic is quite popular with many different types and the identification is quite simple. In the following article, TAELIM will introduce general information about this type of plastic and its specific advantages and disadvantages for you to understand.
Basic information and characteristics of PP plastic
PP plastic, short for Polypropylene, is a polymer with the chemical formula (C3H6)n, produced from the monomer propene (propylene). This is a type of plastic with high mechanical strength and is widely used thanks to its outstanding properties. Below are some characteristics of PP plastic:
- Light weight, transparent white, colorless, odorless, and tasteless.
- Good heat resistance, with the ability to withstand temperatures from 130 – 170°C (melting temperature in the range of 170 – 200°C).
- Safe, non-toxic, easily available on the market at affordable prices.

Simple way to identify PP plastic
PP is a common type of plastic, quite easy to recognize because it has some basic identifying characteristics as follows:
- Good printability, with smooth and transparent surface, helps print clearly.
- High hardness, not as flexible as PE plastic, difficult to stretch but has good bearing capacity.
- Easily torn if there are small cuts or holes.
- Good grease resistance and air permeability, impermeable to water vapor, high durability.
- Outstanding heat resistance: This type of plastic can withstand temperatures above 100°C and the temperature for sealing PP packaging edges is around 140°C.

Summary of popular PP plastic types today
PP (Polypropylene) has three main types that are widely used in life, including: PP scrap plastic, virgin PP granules, and recycled PP granules. Below is detailed information about these types of plastic for you to understand.
PP scrap plastic
PP scrap plastic is a type of plastic recycled from used plastic products. With increasingly improved recycling processes, this type of plastic has become popular because of its low price, ranging from 6,000 - 12,000 VND/kg. PP scrap plastic is not only environmentally friendly but also safe for users.
Virgin PP plastic granules
Virgin PP granules are produced from petroleum, containing no impurities or additives, with a purity of up to 99%. Therefore, this plastic is often used in high-quality products such as water filters. Virgin PP plastic granules are naturally white, highly flexible and durable, and can be combined with colorants to create a variety of products.
PP recycled plastic granules
PP recycled plastic granules are produced from used plastic products such as battery cases, signal lights, cables. Despite its low price, PP recycled plastic still ensures good quality and is often used in granular form in the production process.
Advantages and disadvantages of PP plastic
This type of plastic is quite popular with outstanding features, easy to apply in life. Along with that, there are still some disadvantages that you need to note, which are specifically shared below.
Outstanding features of PP
It is no coincidence that this type of plastic is so widely used. Below is a summary of the outstanding advantages of PP plastic for you to understand:
- High mechanical strength: PP has good elasticity, resistance to deformation and strength.
- Good heat resistance: Can withstand temperatures from 130 - 170°C and melting temperature ranges from 170 - 200°C.
- Waterproof and oxidation resistant: Produced as an outer coating, it helps to block water vapor, grease and some other gases.
- High gloss surface: Increases product aesthetics.
- Safe and versatile: This type of plastic does not contain toxic substances, so it is commonly used in many manufacturing industries and in life.
Disadvantages of PP plastic
Besides the above advantages, this type of plastic has some disadvantages as follows:
- Rapid aging when exposed to sunlight: Polypropylene is susceptible to degradation by UV rays, resulting in PP cracking and deterioration when left outdoors for long periods of time.
- Fragile at low temperatures: This type of plastic has a high coefficient of thermal expansion and contracts at low temperatures, so it is prone to breaking if left in a cold environment, such as a refrigerator.
