Abstract: A flexible polyurethane foam comprises the reaction product of an isocyanate component and an isocyanate-reactive component in the presence of a blowing agent. The isocyanate component comprises a polymeric diphenylmethane diisocyanate component and a monomeric diphenylmethane diisocyanate component. The monomeric diphenylmethane diisocyanate component comprises 2,4′-diphenylmethane diisocyanate and 4,4′-diphenylmethane diisocyanate. The flexible polyurethane foam is substantially free of supplemental flame retardant additives and exhibits flame retardance under flammability tests according to California Technical Bulletin 117 regulations.
Abstract translation: 柔性聚氨酯泡沫包括异氰酸酯组分和异氰酸酯反应性组分在发泡剂存在下的反应产物。 异氰酸酯组分包括聚合二苯基甲烷二异氰酸酯组分和单体二苯基甲烷二异氰酸酯组分。 单体二苯基甲烷二异氰酸酯组分包括2,4'-二苯基甲烷二异氰酸酯和4,4'-二苯基甲烷二异氰酸酯。 柔性聚氨酯泡沫基本上没有补充阻燃添加剂，并且根据加利福尼亚技术公报117规定在可燃性测试下显示出阻燃性。

Abstract: An encapsulated particle comprises a core particle, a transferrable-pesticide disposed about the core particle, and a polyurethane layer disposed about the transferrable-pesticide. The core particle comprises a fertilizer, such as urea. The transferrable-pesticide can comprise a dinitroaniline, such as pendimethalin. The polyurethane layer is generally formed from a reaction mixture having a maximum temperature of no greater than about 30° C. The polyurethane layer inhibits the transferrable-pesticide from transferring to a surface different from the core particle when the encapsulated particle physically contacts the surface. A method of forming the encapsulated particle comprises the steps of encapsulating the core particle with the transferrable-pesticide to form an intermediate-particle, combining an isocyanate and a polyol to form the reaction mixture, and encapsulating the intermediate-particle with the reaction mixture to form the polyurethane layer of the encapsulated particle. The polyurethane layer comprises the reaction product of the isocyanate and polyol.
Abstract translation: 包封的颗粒包括芯颗粒，围绕芯颗粒设置的可转移农药和围绕可转移农药布置的聚氨酯层。 核心颗粒包括肥料，例如尿素。 可转移农药可以包括二硝基苯胺，如二甲戊乐灵。 聚氨酯层通常由最高温度不大于约30℃的反应混合物形成。当包封的颗粒物理接触表面时，聚氨酯层抑制可转移农药转移到不同于核心颗粒的表面。 形成包封颗粒的方法包括以下步骤：用可转移农药包封核心颗粒以形成中间颗粒，将异氰酸酯和多元醇结合以形成反应混合物，并将中间体与反应混合物包封至 形成包封颗粒的聚氨酯层。 聚氨酯层包括异氰酸酯和多元醇的反应产物。

Abstract: A thermoplastic polyurethane is the reaction product of a polybutadiene diol, a polyester diol, and a isocyanate component. The polybutadiene diol has a weight average molecular weight (Mw) of from 200 to 20,000 g/mol. The polyester diol has a melting point of from 40 to 90° C. The reactants allow the thermoplastic polyurethane itself to have a melt flow index measured at 120° C. and 22.6 kg of from 0.1 to 200 grams, per 10 minutes as measured according to ASTM 1238. The thermoplastic polyurethane also has a melting point of from 50 to 300° C. The thermoplastic polyurethane is used to form a composite article.

Abstract: A method of forming a composite article including a first portion comprising a cured elastomer and presenting an engagement surface, and a second portion comprising a thermoplastic composition and presenting a locking surface is disclosed. The method comprises the step of forming a plurality of engagement voids in the engagement surface of the first portion. Each engagement void penetrates into the engagement surface of the first portion and is defined by a side wall which forms an acute angle with the engagement surface. The method also includes the step of applying the thermoplastic composition onto the engagement surface of the first portion to form the second portion such that the locking surface abuts the engagement surface and defines a plurality of locking protrusions disposed in the plurality of engagement voids of the first portion.
