Is polypropylene safe? It is an important question that everyone asks about the safety of their health and the safety of the environment surrounding them. Because plastic is used in many industries around us, Polypropylene is a plastic product. Because this substance is used in many industries, Therefore, we will learn more details about it through the Walitra website and whether it is safe to use or not.
Is polypropylene safe?
For everyone asking whether polypropylene is safe?
- Polypropylene is safer than other materials. That’s why it’s been approved by the Food and Drug Administration.
- This material is used in the preparation of materials that are heated in the microwave because it is not negatively affected by temperatures.
- Many surgical devices and implants are made of polypropylene.
- The Environmental Protection Agency (EPA) states that polypropylene is a material that is derived from petroleum, But it is a very safe option for use in plastic.
- This substance also does not cause cancer in humans and is not flammable in fabrics made of wool.
What is polypropylene?
Polypropylene is a white-colored material that is obtained by crystallizing propylene molecules. It is obtained from oil extracted from crude petroleum derivatives.
This material is also obtained from crude petroleum derivatives at a rate of 97%, and it is an intermediate material in production. Their prices are linked to global crude oil prices.
Types of polypropylene
There are 3 types of polypropylene found in our daily lives:
- Polypropylene is a homopolymer that consists of propylene molecules. It is one of the soft materials used in the manufacture of plastic bags and nylon paper.
- Polypropylene block copolymer, which is a material composed of 3% of ethylene raw material. This material does not tolerate high temperatures. This is why plastic pipes are used to transport cold water only.
- Also, polypropylene is a random copolymer that consists of 3% to 7% of the raw material, which requires high temperature and pressure resistance.
Technical characteristics of polypropylene
Polypropylene random copolymer raw material has many technical specifications, which are:
- Softening Point / Vcat Softening Point (1 kg) up to 132°C
- The melting point is 146 degrees Celsius
- Pull Resistance / Yield Strength (23°C) (50 mm/mm) up to 25 N/mm2.
- Linear Extension Coefficient up to 15 mm/m (°C).
- Charpy Impact Resistance (achieved) (at +23 degrees).
- 52 kJ/m²
- Melt Flow Rate (230 d/2.16 kg) at 0.3
- Density (23°C) is 91 gallons/cm3
- Elongation at Yield (23°C) (50 mm/mm) by 12%.

Tips for safe use of plastic
This set of tips is recommended to be followed when using plastic in order for it to be safe:
- Doctors advise against reheating food in plastic containers. Because the heat that enters the plastic melts some substances that are transferred to the food and make it unhealthy.
- It is also recommended to choose materials made of plastic that are labeled BPA-free because they do not contain harmful chemicals.
- In addition to getting rid of any plastic containers made before 2012 because they were manufactured more than 10 years ago.
- It is not preferable to put hot foods or bread in plastic bags. Because plastic does not interact with food.
- The FDA warns against using BPA in baby bottles, tea cups, and milk containers.
- Bottles labeled single use, It does not have to be refilled and used again.
- From time to time, it is preferable to replace your existing plastic tools and utensils with new ones.
- Or you can buy plastic made from polypropylene because it is considered safer.
In conclusion, after learning the answer: Is polypropylene safe, this material is considered one of the safest materials in the plastic industry. It is recommended to purchase products made from this material because it is safer than other types of plastic.
