What is the difference between HDPE and PE100?

When it comes to plastic piping systems, High-Density Polyethylene (HDPE) and PE100 are two commonly used materials. While they share some similarities, it’s important to understand the key differences between HDPE and PE100 to make informed decisions for your specific application. In this article, we will explore and compare HDPE and PE100, shedding light on their characteristics, benefits, and applications.

Definition and Composition:

HDPE (High-Density Polyethylene):

HDPE is a type of thermoplastic polymer derived from petroleum. It is known for its high strength, durability, and resistance to various chemicals and environmental factors. HDPE is commonly used in piping systems due to its exceptional physical properties and versatility.

PE100 (Polyethylene 100):

PE100 is a specific classification within the polyethylene family, referring to a high-density polyethylene material with a minimum required strength of 10 MPa (megapascals). It is considered a premium grade of polyethylene and offers enhanced performance characteristics.

Material Properties:


Excellent tensile strength and impact resistance, allowing for flexibility and durability.

Good resistance to chemicals, including acids, bases, and solvents.

Low moisture absorption, preventing degradation over time.

UV resistance, making it suitable for outdoor applications.

Wide temperature range tolerance, maintaining its mechanical properties in extreme conditions.


High mechanical strength, surpassing the minimum required strength of 10 MPa.

Improved resistance to crack propagation, ensuring greater durability.

Enhanced resistance to stress cracking, making it suitable for demanding applications.

Excellent resistance to rapid crack propagation (RCP), ensuring the safety of the piping system.

Compliance with specific standards and certifications, guaranteeing quality and performance.




Water supply and distribution networks, including potable water systems.

Sewer and wastewater systems.

Irrigation and agricultural applications.

Gas distribution networks.

Geothermal heating systems.

Mining and industrial piping systems.


High-pressure water and gas distribution networks.

Industrial pipelines for transporting chemicals, acids, and alkalis.

Oil and gas transportation pipelines.

Marine and offshore applications.

Mining applications requiring high-strength materials.

Nuclear and power plant installations.

Standards and Regulations:


HDPE pipes are manufactured according to various standards, including ASTM D3350, ISO 4427, and DIN 8074/8075. These standards specify the dimensions, physical properties, and testing methods for HDPE pipes.


PE100 is a material classification according to ISO 4427 and EN 12201 standards. These standards define the requirements for the quality, dimensions, and performance of PE100 pipes.

Cost Considerations:

HDPE and PE100 pipes are generally cost-effective solutions due to their long service life, low maintenance requirements, and resistance to corrosion and degradation. The specific cost may vary based on factors such as pipe diameter, wall thickness, and the overall project scope.


HDPE and PE100 are both versatile and reliable materials for plastic piping systems. While HDPE is a broad term encompassing various grades, PE100 represents a premium grade of high-density polyethylene. Understanding the differences between HDPE and PE100 allows you to choose the most suitable material for your specific application, ensuring optimal performance, durability, and safety. Whether it’s water distribution, gas transportation, or industrial pipelines, HDPE and PE100 provide excellent solutions for diverse projects in various industries.
