摘要： A process additive for polyolefin films and foams produces products having reduced aging time and reduced greasiness and reduced grease-like transfer as compared to glycerol monostearate (GMS). Carbon dioxide based blowing agents are suitable. The process additive comprises a fatty acid N-aliphatic alcohol amide of the general formula R—CON(R′)R″. R is a fatty hydrocarbon radical having from about 8 to 30 carbons. R′ typically is hydrogen. R′ can also be an alkyl radical of from about 1 to 6 carbons or an alkyl alcohol radical of from about 1 to 6 carbons. R″ is an alkyl alcohol fragment of from about 1 to 6 carbons. The alkyl alcohol fragments can be monohydric or polyhydric. Secondary fatty monoalkanolamides in which R′ is hydrogen are particularly useful, especially stearamide monoethanolamine (MEA). The benefits of the invention can be achieved and enhanced in some examples by mixing the fatty acid N-aliphatic alcohol amide with an ester of a long chain fatty acid with a polyhydric alcohol, including GMS. Examples of fatty acid N-aliphatic alcohol amides include cocamide MEA, lauramide monoisopropylamine (MIPA), oleamide MIPA, and stearamide 2,3-propanediol.

摘要： A method for accelerating the release of a flammable blowing agent from an expanded foam is disclosed. According to the method, an expanded foam structure is perforated to form a first series of channels extending partially through its thickness from a first surface and a second series of channels extending partially through its thickness from a second surface opposite the first surface. The channels provide paths enabling the blowing agent to escape more rapidly from the interior of the expanded foam structure.

摘要： Ionomer present in a polyethylene resin from about 1 to 40% by weight of the resin produces superior extruded foam sheet products that approach the pore size and resiliency of foams prepared from chemical blowing agents. The results can be achieved at normal extrusion rates and on standard extrusion foaming equipment.
