LDPE foam is a kind of low-density polyethylene foam made by the LDPE raw plastic resin, the density is low to 28kg/m3 soft and light features. The foam is an ideal material for the packing industry to anti-shock.
Cross-Linked LDPE Foam
Cross-linked LDPE foam ties all the polymer molecules together. Because the molecules are tied to together, they haven't easily torn apart from each other. Cross-linking makes both elastomers and plastics stronger, improving the physical properties such as tensile, elongation, and tear strength. Radiation cross-linked polyethylene foam is manufactured via a continuous process.
The cross-linked foam tends to be softer than extruded foam, and somewhat more uniform.
