What is Low-Density Polyethylene Foam?
Low-density polyethylene (LDPE) foam is a premium closed-cell thermoplastic foam composed of microscopic interlocking cells that prevent the passage of water or air. This design gives LDPE foam a semi-rigid structure, providing both flexibility and durability.
Manufactured via high-pressure free radical polymerization, LDPE foam is lightweight, resilient, and reliable, making it an ideal material for numerous industrial and commercial uses.
Why Use Low-Density Polyethylene Foam Strips?
LDPE foam strips are cut to customer-specified lengths and offer versatile solutions for:
- Filling gaps and irregularities between surfaces
- Reducing noise and vibrations
- Creating seals against air, gas, dust, and liquids
Due to their non-toxic, water-resistant, and non-corrosive properties, LDPE foam strips are widely used in:
- Packaging containers and dispensing bottles
- Tubing and plastic components
- Electronics and computer devices
- Protective packaging solutions
