Combination of a resilient polyurethane foam and an upholstery covering material with improved resistance to ignition.

摘要

A resilient polyurethane foam with improved resistance to ignition which passes the flame test of BS 5852: Part 1 for material-covered fillings as used for upholstered furniture when adapted for testing the foam only, which foam has on at least one surface thereof at least one coating of a vinylidene chloride polymer of a composition thereof which polymer or composition is substantially absent from the interior of the foam, the amount of chlorine in the at least one vinylidene chloride polymer or composition thereof being at least 60% by weight based on the weight of vinylidene chloride polymer. The coating preferably incorporates a synergist compound, e.g. an oxide or sulphide of antimony. Also, a combination comprising a coated resilient polyurethane foam and a covering material which passes the flame test as carried out according to BS 5852: Part 1.
