• Packaging: Production of bottles for milk, detergents, oils, food containers, and plastic bags.
• Piping systems: Used in water and gas pipes, sewage systems, and irrigation tubes due to corrosion and chemical resistance.
• Construction: Manufacturing of geomembranes for landfills, water tanks, and protective linings.
• Cables and wires: Insulation for electric cables due to excellent dielectric properties.
• Household items: Cutting boards, crates, containers, and other everyday products.
• Toys: Production of durable toys like building blocks and outdoor play equipment.
• Automotive industry: Used in fuel tanks, bumpers, and other vehicle components.
• High strength and durability: HDPE offers excellent impact and wear resistance, ensuring long product life.
• Chemical resistance: The material resists many chemicals, making it suitable for harsh environments.
• Low weight: Despite its strength, HDPE is lightweight, simplifying transport and installation.
• Moisture resistance: HDPE does not absorb water, ideal for waterproof applications.
• Easy processing: The material is easily shaped using various techniques such as injection molding, extrusion, and blow molding.
• UV sensitivity: Long
• term exposure to sunlight can degrade the material; adding UV stabilizers can mitigate this issue.
• Difficult to bond: Due to low surface energy, HDPE is hard to glue without proper surface treatment.
• Limited heat resistance: HDPE withstands temperatures up to approximately 120 °C for short periods, limiting high
• temperature applications.
