The influence of adhesive joint characteristics of the bonded samples of PUR-foam

Upholstered chairs and upholstered furniture in general, is largely produced primarily using PUR-foams, and it largely in the form of gluing several types of foam and himself on a firm surface - usually plywood or the agglomerated material – for the qualitative increase of upholstered furniture (including seating). Work deals with properties of the bond in connection with the influence on the final properties of the finished product, or even a change of functional properties in use over time. This work deals with: The influence of the characteristics of the adhesive used on samples bonded polyurethane foams. This work deals with properties of the bond in connection with an influence on the final properties of the finished product, or changes in functional properties when used at the time. The work is focused on: Effect of glue applied to the characteristics of the bonded samples of PUR foam. To determine the effects observed were used as the basis for the methodology based on the standard EN 1957, which was further modified as necessary. The results of the tests and conclusions can be stated that the incidence of bonded joints, ultimately, has a negligible effect on the resulting observed characteristics and therefore can cut and paste samples of smaller sizes into larger blocks without a fundamental change of the original features.
