HDPE Resin
What is HDPE?
High-density polyethylene a type of thermoplastic polymer characterized by its high strength-to-density ratio. HDPE is one of the most widely used plastics in the world. It is a member of the polyethylene family of plastics, which also includes low-density polyethylene (LDPE)
Characteristics and Properties
• High Density: As the name suggests, HDPE has a higher density compared to LDPE. This results in greater strength, stiffness, and resistance to impact.
• Chemical Resistance: HDPE is highly resistant to chemicals, making it suitable for applications where contact with corrosive substances is a concern. It is commonly used for chemical storage tanks and pipelines.
• Low Moisture Absorption: HDPE has low moisture absorption, which makes it ideal for outdoor applications and products that need to resist moisture, such as water pipes and outdoor furniture.
• Excellent Durability: HDPE is known for its durability and resistance to wear and tear. It is often used in products like plastic lumber, playground equipment, and road barriers.
• Food Safe: HDPE is considered food-safe, and it is used for food packaging, food containers, and cutting boards.
• UV Resistant: HDPE has good resistance to ultraviolet (UV) radiation, making it suitable for outdoor applications that are exposed to sunlight, such as water tanks and agricultural equipment.
• Recyclability: Like LDPE, HDPE is recyclable, and it is commonly collected in recycling programs to reduce environmental impact.
Applications
• Pipe and Duct Systems: HDPE pipes are widely used for water and gas distribution, as well as in the construction of underground utilities like drainage and sewer systems.
• Rotational Molding: HDPE is a common material for rotational molding, used to create large, hollow objects like tanks, containers, and playground equipment.
• Industrial and Agricultural Equipment: HDPE is used in the manufacturing of parts and components for industrial machinery and agricultural equipment due to its strength and durability.
• Automotive Parts: Some automotive components, such as fuel tanks, bumpers, and interior trim, are made from HDPE.
