What Are the Three Types of PPR?

PPR (Polypropylene Random Copolymer) pipes and fittings have become a popular choice for plumbing and water systems across residential, commercial, and industrial sectors. Known for their durability, thermal resistance, and long service life, PPR materials are especially valued in hot and cold water supply systems.

But did you know there are three main types of PPR? Understanding these types is essential if you’re planning a project or sourcing materials.

In this article, we’ll break down the three common types of PPR, their differences, and where they are best used.


🔍 What Is PPR?

PPR, short for Polypropylene Random Copolymer, is a thermoplastic used in piping systems. It’s lightweight, corrosion-resistant, and weldable through heat fusion—making it a preferred material for both domestic and commercial applications.

It typically conforms to DIN 8077/8078 and ISO 15874 standards, ensuring quality and compatibility across the plumbing industry.


✅ The Three Types of PPR

1. PPR Type 1 (PP-H – Polypropylene Homopolymer)

Description:
PPR Type 1, also called PP-H, is made from polypropylene homopolymer. It was one of the earliest polypropylene materials used in piping.

Features:

  • High rigidity
  • Good chemical resistance
  • Suitable for industrial applications

Limitations:

  • Lower impact resistance
  • Less suitable for cold environments

Best For:

  • Industrial fluid handling
  • Chemical transport
  • Compressed air systems

2. PPR Type 2 (PP-B – Polypropylene Block Copolymer)

Description:
PPR Type 2, or PP-B, is a block copolymer made by adding ethylene units to improve impact strength and flexibility.

Features:

  • Better toughness than Type 1
  • Good cold temperature performance
  • Suitable for drainage and non-pressure systems

Best For:

  • Drainage and wastewater
  • External piping systems
  • Low-pressure water transport

3. PPR Type 3 (PP-R / PP-R80 – Polypropylene Random Copolymer)

Description:
Type 3 is the most advanced and widely used PPR material, made from polypropylene random copolymer (PP-R). It offers an ideal balance of strength, flexibility, and temperature resistance.

Features:

  • High pressure and temperature resistance
  • Suitable for both cold and hot water
  • Long lifespan (50+ years)
  • Non-toxic and safe for drinking water
  • Fusion-weldable for leak-proof joints

Best For:

  • Domestic plumbing
  • Hot and cold potable water
  • Radiant floor heating
  • Industrial fluid transport

Most modern PPR piping systems use Type 3 (PP-R) because of its superior performance.
