  • Publication number: 20210140102
    Abstract: This invention relates to a carpet tile that includes a polyolefin secondary backing layer. In particular, this invention relates to modular carpet tiles having at least one layer of polyolefin-containing thermoplastic polymer in the secondary backing of the carpet tile. By modifying the composition of the carpet tiles in this manner, the carpet tiles are able to withstand the high temperatures associated with surface printing of the tiles, while still maintaining cold temperature flexibility.
