Low-density polyethylene (LDPE)
One form of polyethylene that is widely utilized in many different industries is low-density polyethylene (LDPE), which is distinguished by qualities including high flexibility, resilience to shock and impact, waterproofing, chemical resistance, and processability.
This grade is primarily used as a packaging material. Among the widely used applications of this polymer in the packaging sectors are food storage containers, bottles, plastic bags, and packaging films. This polymer is also utilized in the production of fluid-transporting pipes.
LDPE is utilized in a variety of various applications, including as the packaging sector, medical gadgets, children’s toys, and insulating materials, because of its great flexibility and moderate resistance to breakage.
While HDPE is renowned as a high-density polymer with stronger mechanical resistance for applications needing high resistance to impact and pressure, LDPE is acknowledged as a flexible low-density polymer appropriate for applications requiring easy flexibility and shaping.
