LDPE (Low Density Polyethylene)
Low density polyethylene (LDPE) is an extruded engineered plastic that offers good corrosion resistance properties and low moisture permeability. It can be used in applications where corrosion resistance is a factor, but stiffness, high temperatures, and structural strength are not.
For these applications refer to it’s counterpart high density polyethylene (HDPE). LDPE is easy to fabricate, vacuum form, and weld. In applications requiring low temperature flexibility, toughness and durability LDPE can be an excellent cost effective option. Low density polyethylene is resistant to stress–cracking.
Common applications for LDPE include water and chemical transportation. LDPE is to be used in outdoor applications where UV rays are a factor. Black LDPE is recommended to improve durability. Low density polyethylene has heat distortion temperature of 120°F.
Thermoplastic LDPE is often used to create corrosion-resistant work surfaces, trays and containers.

More about Low density polyethylene (LDPE)
LDPE was first produced in 1933 by Imperial Chemical Industries. It was the first polyethylene made. It is still a widely used thermoplastic due to its excellent properties.
