Description
HDPE 52518 – High-Density Polyethylene for Injection Molding Applications
HDPE 52518 is a specialized high-density polyethylene grade produced by Jam petrochemcal Co designed specifically for injection molding applications. Produced through a gas-phase polymerization process, this material offers a balanced combination of excellent mechanical strength, thermal stability, and high flowability. These properties make HDPE 52518 ideal for manufacturing precise, thin-walled, and complex parts, especially in industries where production efficiency and quality are essential.
Key Features
One of the standout characteristics of HDPE 52518 is its high melt flow index (MFI), which is approximately 18 g/10 min (measured according to ASTM D1238). This high MFI allows the resin to flow smoothly within molds, ensuring that even intricate shapes are filled evenly and completely.
With a density of around 0.952 g/cm³, HDPE 52518 falls under the category of high-density polyethylenes, offering excellent stiffness and rigidity. Its flexural modulus of approximately 1200 MPa ensures strong structural performance in the final molded products.
Moreover, this grade exhibits good impact resistance and a Vicat softening point of about 121°C, making it suitable for components that must endure both thermal and mechanical stresses.
Versatile Applications
HDPE 52518 serves a wide range of industries. In the household goods sector, it is commonly used to produce containers, lids, and various plastic components. Its safety and formability also make it a preferred material in the toy industry. In the packaging sector, it is widely used for manufacturing bottle caps, chemical-resistant containers, and other durable packaging elements.
In addition, this grade is well-suited for industrial applications such as the production of precision parts like small gears, protective casings, and fittings that require resistance to harsh environments.
Chemical Resistance and Processing Stability
One of the notable advantages of HDPE 52518 is its excellent resistance to a wide range of chemicals, including acids, bases, solvents, and many organic compounds. This chemical resistance makes it highly reliable for use in contact with reactive substances.
The grade also contains thermal stabilizers and catalyst residue neutralizers, which enhance its processing stability, reduce degradation during production, and help maintain consistent product quality.
Conclusion
In summary, HDPE 52518 is a high-performance polyethylene resin that meets the needs of manufacturers seeking efficiency, reliability, and durability in their injection molding operations. Its blend of mechanical strength, easy processability, and long service life makes it a dependable solution for various consumer and industrial plastic products.
