This surface treatment reacts to form a polymeric coating thereby reducing both the free moisture and soluble soda level. This improved filler results in superior physical properties in polymer resins and improved processing characteristics in urethane foams.Field of SearchIncluding synthetic resin or polymerPreparing a cellular product utilizing a stated ingredient which is surface coated or is a discrete solid particle containing a fluid encapsulated therein, processes of forming an expandible composition, containing said stated ingredient or composition therefrom Ingredient contains a metal atom Metal atom is part of an organic compound At least one polymer is derived from a polycarboxylic acid or derivative and a polyol or wherein the polymer-forming system containing the same type of reactants POLYURETHANE CELLULAR PRODUCT CONTAINING UNREACTED FLAME-RETARDANT MATERIAL NONURETHANE FLAMEPROOFED CELLULAR PRODUCT Intumescent coating or ablative composition or process of preparing Process of forming a composition of a solid polymer or solid polymer forming system by admixing a product in the form of a surface coated, impregnated, encapsulated, or surface modified fiber, sheet, particle, or web, with a material; or composition which is the result of said admixing Product having a solid synthetic polymer or solid polymer-forming system Sulfur bonded directly to three oxygen atoms Nitrogen Aryl group which is not fused or bridged Organic chalcogen other than oxygen as DNRM | |
