Problems solved by technology

For example, while it is possible to obtain recycled carpet or carpet tile by using recycled face fibers, a polypropylene primary backing, and a vinyl-containing adhesive material, when such carpet has a polyurethane foam backing, the foam backing Lining is not easy to be compatible with other materials
Often this adversely affects the mechanical properties (e.g. tensile and impact strength) and aesthetic properties of articles made from such mixtures
While multiple components can be separated from each other before being used for product recovery, the separation process typically requires significant time and energy to perform

Embodiment 1

[0098] All samples contained 1% oil (Sunpar 150 paraffin oil, Sun Chemicals, Philadelphia, PA).

[0099] Unless otherwise stated, all samples contained post-added blowing agent mixed. (Note that the % of post-added blowing agent is relative to the mixture without blowing agent). The blowing agent is supplied as a 50% LDPE masterbatch formulation.

[0100] The compression resistance value is the average of 3 values.

[0101] Compression set and density are taken from a single measurement.

[0102] The samples consisted of fiberglass material foam as shown. The fiberglass material was applied according to the in situ method described in this application.

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Provisional Patent Application No. 60 / 684,393, filed May 25, 2005, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to foam cushion backings. More particularly, the present invention relates to foam cushion backings suitable for use in carpet and carpet tile products. The present invention also relates to carpet and carpet tile products backed with a foam backing. The present invention also relates to methods of making foam cushion backings, carpets and carpet tiles of the type described in this application. Background technique [0004] Foam underlayment is commonly used as a backing for carpet or carpet tile products. When rugs and carpet tiles are backed with backing, they will last longer than products without these backings. Specifically, when pressure is applied to the carpet surface yarns of a carpet or c...
