Hanwha High-Density Polyethylene (HDPE) Product Details
High-Density Polyethylene (HDPE) Product Description
High-Density Polyethylene (HDPE) is a versatile thermoplastic polymer known for its high strength-to-density ratio, excellent impact resistance, and chemical stability. It is widely used across various industries due to its durability, lightweight nature, and resistance to moisture and many chemicals. HDPE is commonly utilized in applications such as packaging, piping, geomembranes, and plastic lumber.
Production Process
HDPE is produced through the polymerization of ethylene monomers. The two primary methods are:
Slurry Polymerization (Ziegler-Natta Process): Utilizes catalysts to produce HDPE with minimal branching, resulting in high-density material.
Gas Phase Polymerization: Employs a fluidized bed reactor to produce HDPE under controlled temperature and pressure conditions.
The choice of process affects the polymer’s properties, allowing customization for specific applications.
Product Specifications
HDPE resins are available in various grades, each tailored for specific applications. Below is a table summarizing typical properties:
| Property | Test Method | Typical Value |
|---|---|---|
| Density | ASTM D792 | 0.940 – 0.976 g/cm³ |
| Melt Index (190°C/2.16 kg) | ASTM D1238 | 0.35 g/10 min |
| Tensile Strength at Yield | ASTM D638 | 3,900 – 4,700 psi (27 – 32 MPa) |
| Flexural Modulus | ASTM D790 | 174,000 – 237,000 psi (1,200 – 1,635 MPa) |
| Elongation at Break | ASTM D638 | >600% |
| Vicat Softening Temperature | ASTM D1525 | 126°C (259°F) |
| Environmental Stress Crack Resistance (ESCR) | ASTM D1693 | 50 hours |
Note: Values may vary depending on the specific grade and manufacturer.
Applications
HDPE’s unique properties make it suitable for a wide range of applications, including:
Packaging: Bottles, containers, and plastic bags due to its strength and food-safe characteristics.
Pipes and Fittings: Used in water and gas distribution systems for its durability and corrosion resistance.
Construction Materials: Geomembranes, plastic lumber, and corrosion-resistant materials.
Consumer Goods: Household items like cutting boards, toys, and storage sheds.
Agriculture: Irrigation pipes and agricultural films.
Automotive: Fuel tanks and other components requiring chemical resistance.
Packaging and Transportation
Packaging: HDPE resins are typically supplied in pellet form, packaged in 25 kg bags or bulk containers, depending on customer requirements.
Transportation: Due to its lightweight nature, HDPE is cost-effective to transport. Products should be handled to prevent damage, and storage conditions should protect against UV exposure to maintain material integrity.
