Polyethylene in Iran

Introduction

In recent decades, the use of polymer materials in the pipe manufacturing industry has experienced significant growth. One of the most important polymer materials in this field is Pipe Grade Polyethylene Compound, which is widely used in the production of drinking water pipes. This compound must meet specific mechanical, physical, and chemical properties to ensure the safety, health, and durability of water distribution systems.

SABICO, a leading knowledge-based company, plays a crucial role in the production and development of such compounds according to national and international standards.
