| 摘要 |
The invention provides a method for providing a flame retardant thermal insulation between a plurality of spaced apart surfaces having an air-filled cavity between them, which comprises introducing into said cavity a mixture containing cellular particles of expanded polymer, a synthetic polymer latex binder, and an organic bromine-containing compound conferring flame retardant properties on the bound polymer particles, preferably in the form of a flowable suspension concentrate of a solid flame retardant. The invention provides also, for use in the method, a suitable mixing gun and a flowable suspension concentrate of flame retardant. |
