A carpet or carpet tile comprising a textile top cloth, a precoating layer and a backing layer, wherein the backing layer comprises a backing composition, wherein the backing composition comprises:
- a rosin or a derivative thereof;
- a non-fossil natural oil which is optionally refined or modified;
- optionally, a thermoplastic elastomer;
- and
- a filler,
- wherein the backing composition comprises no more than 5% by weight of a polyolefin polymer.
A carpet or carpet tile comprising a textile top cloth, a precoating layer, and a backing layer, wherein the backing layer comprises a backing composition, wherein the backing composition comprises a binder, wherein the binder comprises:
- a rosin or a derivative thereof;
- a non-fossil natural oil which is optionally refined or modified;
- and
- optionally, a thermoplastic elastomer,
- wherein the binder comprises at least 85% by weight bio-based materials.
A carpet or carpet tile comprising a textile top cloth, a precoating layer, and a backing layer, wherein the backing layer comprises a backing composition, wherein the backing composition comprises a filler and a bio-based binder, the bio-based binder consisting essentially of
- a rosin or a derivative thereof;
- a non-fossil natural oil which is optionally refined or modified;
- and
- optionally, a thermoplastic elastomer.
