152cm x 40m. 100% Knitted and Brushed Polyester Fabric Laminated to 3.5mm Foam with a 20 Denier Nylon Backing. The tricot open weave backing provides a barrier between the foam and the adhesive to reduce the risk of excess adhesive being sprayed onto the foam. The circular knit weave provides extra two way stretch for difficult shaped headlinings. Foam backed headlining is suitable for all glue type automotive applications.
