Abstract:
Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

Abstract:
A phenolic foam is made by foaming and curing a formable phenolic resin composition that comprises a phenolic resin, a blowing agent, an acid catalyst and an inorganic filler. The blowing agent comprises a blend of chlorinated aliphatic hydrocarbon containing 2 to 5 carbon atoms and an aliphatic hydrocarbon containing from 3 to 6 carbon atoms mixed in a ratio of 60/40 to 95/5 parts by weight. The inorganic filler is at least one selected from a metal hydroxide, a metal oxide, a metal carbonate and metal powder. The phenolic foam has a pH of 5 or more and a water uptake less than 1 kg/m2. A phenolic foam with a higher pH value compared with conventional phenolic foam reduces corrosion risk when in contact with metallic materials. The phenolic foam maintains excellent long-term stable thermal insulation performance, low water uptake and fire resistance performance and by using the said blowing agent, does not harm the environment as an ozone or global warming depleting material.
