Abstract
The present disclosure relates to a carpet backing composition comprising a first polymer component, a filler, and a compatibilizer that can provide free radial resource for performing bonding functions of the first polymer component and the filler. The composition can exhibit good melt strength/extrudability and low viscosity. The present disclosure also relates to a carpet backing or a carpet that comprises such carpet backing composition.
Claims24
A carpet backing composition comprising:
- (a) about 10 wt % to about 50 wt % of a first polymer component by weight of the composition, the first polymer component comprising an elastomeric polymer;
- (b) about 50 wt % to about 90 wt % of a filler by weight of the composition;
- and
- (c) about 0.1 wt % to about 5 wt % of a compatibilizer by weight of the composition, the compatibilizer providing free radical source to bond the first polymer component and the filler.
A composition comprising:
- (a) about 10 wt % to about 50 wt % of a first polymer component by weight of the composition, the first polymer component comprising an elastomeric polymer;
- (b) about 65 wt % to about 85 wt % of a filler by weight of the composition;
- (c) about 0.1 wt % to about 10 wt % of a second polymer component by weight of the composition, the second polymer component having a melt flow rate, determined at 230° C. and 2.16 kg weight, of about 250 g/10 min or greater;
- and
- (d) about 0.1 wt % to about 3 wt % of a compatibilizer providing free radical source by hydrolysis reaction to bond the polymer components and the filler, by weight of the composition.
A carpet comprising:
- (a) a primary backing layer which has a face and a back surface;
- (b) a plurality of fibers attached to the primary backing layer and extending from the face of the primary backing layer and exposed at the back surface of the primary backing layer;
- and
- (c) a secondary backing layer comprising a carpet backing composition,
- wherein the carpet backing composition comprising:
- (i) about 10 wt % to about 50 wt % of a first polymer component by weight of the composition, the first polymer component comprising an elastomeric polymer;
- (ii) about 50 wt % to about 90 wt % of a filler by weight of the composition;
- and
- (iii) about 0.1 wt % to about 5 wt % of a compatibilizer by weight of the composition, the compatibilizer providing free radical source to bond the first polymer component and the filler.
