Granule EX3 is a type of High-Density Polyethylene (HDPE), specifically a copolymer with high density. Due to the compactness of its molecular chains, it has less flexibility but demonstrates good resistance to chemicals and environmental stress. Granule EX3 is ideal for use in various applications such as water and gas pipelines, large containers, toys, chemical housings, and packaging. Due to its strong resistance to stress cracking and impact strength, it is also widely used in the production of plastic components and pressure pipes.

Overall, Granule EX3, with its low molecular weight, high chemical resistance, and versatility in various environments, is commonly used in many industries.

Technical Features of Granule EX3

Chemical Composition
Granule EX3 is made from high-density polyethylene (HDPE), produced as a colorless copolymer. This material is obtained via the polymerization of ethylene gas and features high density, which is attributed to the compactness of its molecular chains.

Physical Properties
Granule EX3 has a low molecular weight, which reduces its flexibility but increases its rigidity and strength. With its simple and compact structure, it shows high resistance to environmental and chemical conditions.

Mechanical Properties
Due to its high density, Granule EX3 is highly resistant to impact and pressure. It also shows good resistance to stress cracking caused by environmental factors, making it ideal for use in water and gas pipelines.

Optical Properties
As a colorless material, Granule EX3 allows for the use of pigments and UV stabilizers, making it suitable for outdoor applications exposed to sunlight.

Mechanical Properties of Granule EX3

• Tensile Strength: Granule EX3 exhibits high tensile strength, enabling it to resist mechanical tension and pressure effectively. This property is especially important in products that require high-pressure endurance, such as water and gas pipelines.

• Flexural Strength: The granule has good resistance to bending, making it suitable for applications that require both flexibility and strength.

• Impact Resistance: Thanks to its dense structure, Granule EX3 offers strong resistance to mechanical impacts. This is particularly critical for products like plastic components and pressure pipes.

• Creep Resistance: Granule EX3 demonstrates good resistance to creep, which is the deformation of material under a constant load over time. This feature is crucial for applications requiring shape stability over long periods.

Thermal Properties of Granule EX3

• Melting Point: Granule EX3 has a relatively high melting point, around 130 to 135°C. This enables it to maintain stability at elevated temperatures and ensures proper forming during processing.

• Thermal Stability: Granule EX3 is thermally stable and maintains its physical and mechanical properties well even at high temperatures, making it suitable for extrusion processes and applications requiring high thermal resistance.

• Thermal Expansion Coefficient: Granule EX3 has a moderate thermal expansion coefficient, which means it undergoes minimal dimensional changes with temperature fluctuations. This is especially important for applications that require dimensional precision.

• Heat Resistance: This granule can withstand high temperatures without losing shape or mechanical strength. This property is particularly vital for parts exposed to heat, such as hot material transfer pipes.

These features make Granule EX3 a great choice for industries requiring high resistance to harsh environmental conditions and thermal stability.
