Introduction
HDPE PE100 (high density polyethylene, grade PE100) is one of the most widely used and resistant plastic materials in various industries. This material has been noted for its outstanding properties such as high strength, corrosion resistance and long-term durability, especially in the construction of pipes and water and gas transmission systems. In this article, we will explore the features, uses and benefits of HDPE PE100 and explore the reasons for its popularity in the industry.
Definition of HDPE PE100
HDPE PE100 (High-Density Polyethylene – PE100) is a type of high-density polyethylene that, due to its specific technical characteristics, is used in various industries, especially for the construction of high-pressure pipes, water and gas transmission systems, and infrastructure applications. PE100 is known as a material resistant to high pressures, harsh environmental conditions and corrosive chemicals. The properties of this material include high strength, crack resistance, long life and good flexibility, which make it ideal for engineering and industrial applications.
Key features of HDPE PE100
– Pressure resistance: PE100 has a higher pressure resistance than other HDPE grades such as PE80. This feature makes it suitable for use in high pressure piping systems (such as water supply and gas supply networks).
– Resistance to cracking: This material has a very good resistance to cracking caused by environmental stresses, which increases the useful life of the pipes made of it.
– Chemical resistance: PE100 has a high resistance to many chemicals such as acids and bases, which makes it suitable for use in industrial environments.
– UV resistance: pipes made of PE100 can be exposed to sunlight for a long time without losing their quality and mechanical properties.
Type of polyethylene
HDPE PE100 is divided into several main types based on different characteristics and applications. Each type is produced for use in specific conditions and diverse engineering needs. Some of the main types of HDPE PE100 are:
۱٫ Standard PE100 This type of HDPE PE100 is used for general piping applications such as water and gas networks. It has excellent resistance to pressure, corrosion, and UV rays and is suitable for installation in different environments.
۲٫ PE100 RC (Resistant to Crack) This type of PE100 is more resistant to cracking caused by environmental stresses. PE100 RC is typically used in situations where hard and rocky soils or environments are present or where the risk of cracking is increased.
۳٫ PE100 HSCR (High Stress Crack Resistant) This type of PE100 has excellent resistance to cracking and high mechanical pressures. HSCR is used in projects that require high resistance to long-term stresses and specific environmental conditions.
۴٫ PE100+ This type of polyethylene is produced according to higher standards and approved by a global organization called PE100+ Association. PE100+ is at a higher level than other PE100 types in terms of quality and longevity and is usually used in critical projects such as gas and drinking water transmission lines.
۵٫ PE100 Black This type of HDPE PE100 is specifically designed to resist UV rays and outdoor environments. PE100 Black is commonly used in applications where pipes are exposed to sunlight for long periods of time.
Each of these types are selected based on the environmental conditions and specific needs of the project to provide maximum efficiency and durability.
How is HDPE PE100 produced?
The production process of HDPE PE100 includes several stages, starting from the polymerization of ethylene and ending with the production of the final product in the form of pipes and industrial parts. In this process, advanced methods and precise control of temperature and pressure are used to produce a material with superior mechanical and physical properties. The production steps of HDPE PE100 are as follows:
۱٫ Ethylene polymerization The HDPE PE100 production process begins with ethylene polymerization. In this step, molecules of ethylene, which is a light gas, are linked together under high pressure and temperature to form polyethylene. To produce PE100, special catalysts are used to form polymers with high density and long chains. This high density improves the mechanical resistance and longevity of the product.
۲٫ Additive Additives After the base polymer is produced, various additives are added to it to provide desirable properties such as ultraviolet (UV) resistance, crack resistance, and improved performance at high or low temperatures. These additives usually include antioxidants, UV stabilizers, and pigments that are used to provide greater resistance and improve the performance of the final material.
۳٫ Melting and extrusion After adding additives, the polyethylene mixture is directed into the extruder. In this step, the polymer is melted at a high temperature and is shaped into a tube or other final product through special molds. The high-pressure extruder pushes the polymer through the mold and creates a continuous product that takes its final shape after cooling.
۴٫ Cooling and cutting After the tube or product exits the extruder, it is cooled quickly in water baths or using air. This cooling helps to maintain the shape and structure of the product. Then the products are cut according to customer needs and standard sizes.
۵٫ Testing and quality control HDPE PE100 pipes and products are subjected to various tests after production to evaluate their quality and performance. These tests include pressure resistance, cracking resistance, UV stability and chemical evaluation. This step is important to ensure that the products comply with international standards and the specific needs of the projects.
۶٫ Packaging and distribution After passing the quality tests, the pipes and manufactured products are ready to be distributed in the form of standard packages. Packaging is done in such a way that the products are not damaged during transportation and reach the final destination correctly.
Due to the use of advanced technologies and precise control, this production process produces a product with favorable mechanical and physical characteristics that is used in various industries such as water supply, gas supply, and chemical transfer systems.
