  • HIGH TEMPERATURE NON-CROSSLINKED POLYETHYLENE-BASED FOAM AND METHOD OF MAKING THE SAME
    Publication number: 20220025141
    Abstract: A linear low density polyethylene (LLDPE) foam and methods of making the same are described. The LLDPE foam has a maximum operating temperature of about 220° F. The LLDPE foam can also have a density in the range of from 0.6 to 10.0 lbs/ft3. The LLDPE foam can be manufactured in part by processing an LLDPE resin in order to create a long branch molecular structure in the LLDPE resin without crosslinking or otherwise adversely affecting the thermoplastic properties of the LLDPE resin.
