    • An adhesive composition is described that is particularly useful for application to the plastic nonwoven materials found in personal hygienic articles. The composition includes first and second ethylene vinyl acetate copolymers. The first copolymer has a high molecular weight characterized by a melt viscosity at 150 °C, of 100 Pascals per second or more. The second copolymer has a low molecular weight characterized by a melt viscosity at 150 °C of 50 Pascals per second or less. The second copolymer is present in an amount by weight percent less than or equal to the amount by weight percent of the first ethylene vinyl acetate copolymer. The composition also includes at least one tackifier resin, a hydrocarbon wax present in an amount from 0.5 % to 10 % by weight of the composition; and, a liquid plasticizer present in an amount up to 20 % by weight of the composition.
    • 描述了一种粘合剂组合物,其特别适用于在个人卫生用品中发现的塑料非织造材料。 该组合物包括第一和第二乙烯乙酸乙烯酯共聚物。 第一共聚物具有高分子量,其特征在于在150℃下的熔体粘度为100帕斯卡每秒或更多。 第二共聚物具有低分子量,其特征在于150℃下的熔体粘度为50帕斯卡/秒或更低。 第二共聚物以小于或等于第一乙烯 - 乙酸乙烯酯共聚物的重量百分比的量的量存在。 组合物还包括至少一种增粘树脂,烃蜡的含量为组合物重量的0.5%至10%; 和以组合物的至多20重量%的量存在的液体增塑剂。
