For easy identification, most plastic containers are marked with a recycling symbol containing a specific number. What is the specific number given for Low-Density Poly Ethylene (LDPE)? Correct Answer 4

4 is the specific number given for Low-Density Poly Ethylene (LDPE).

Important PointsLDPE (4):

  • A thermoplastic made from the monomer ethylene.
  • LDPE (low-density polyethylene) is a soft, flexible, lightweight plastic material.
  • LDPE is noted for its low-temperature flexibility, toughness, and corrosion resistance.
  • It is not suited for applications where stiffness, high-temperature resistance, and structural strength are required.

Additional InformationHDPE (2):

  • It is a strong, durable, lightweight, and chemically resistant plastic material popular for a variety of applications.
  • It is easy to fabricate and weld using thermoplastic welding equipment and is an excellent choice for fabricated water tanks and chemical tanks.

 

Polyvinyl Chloride (PVC) (3):

  • It is a high-strength thermoplastic material widely used in applications, such as pipes, medical devices, wire, and cable insulation.

 

7 (Other):

  • It includes all other types of biodegradable and non-biodegradable plastic resins that fall in this category.
  • Made by mixing different types of resins.
  • Used in making sunglasses, nylon clothes.
