What are the differences between MDPE vs HDPE?

## What are the differences between MDPE vs HDPE?

1. **What is MDPE?**.

MDPE stands for Medium Density Polyethylene, which is a type of plastic commonly used in gas distribution piping and fittings due to its flexibility and resistance to cracking.

2. **What is HDPE?**.

HDPE stands for High Density Polyethylene, which is a type of plastic known for its high strength-to-density ratio and is often used in applications such as water pipes, storage tanks, and milk jugs.

3. **Differences between MDPE and HDPE**.

- **Density:** The main difference between MDPE and HDPE lies in their density. MDPE has a medium density, while HDPE has a higher density.

- **Strength:** HDPE is stronger than MDPE, making it suitable for applications where higher strength is required.

- **Flexibility:** MDPE is more flexible than HDPE, which allows it to withstand greater amounts of bending and stretching.

- **Applications:** MDPE is commonly used in gas distribution piping, while HDPE is used in water pipes, storage tanks, and other high-strength applications.

4. **Conclusion**.

In summary, MDPE and HDPE are both types of polyethylene plastics with different densities and properties. MDPE is more flexible, making it ideal for gas distribution piping, while HDPE is stronger and used in applications requiring higher strength. It is important to choose the right type of plastic for each specific application to ensure optimal performance and longevity.
