摘要:
Adhesive compositions rendered the hot rolled articles and methods for production of laminated elastic.A composition adevisa hot melt comprising a mixture of components that includes about 10% to about 40% by weight of a block copol\u00edmetro elastomeric, preferably styrene - isoprene - est\u00edreno (SIS) or styrene butadiene styrene (SBS).About 15% to about 70% by weight of a first resin promoter of tackiness of median group having a softening point of at least about 110 < 198 > C and having a conte\u00b4\u00b4udo aromatic of at least about 1.5% by weight about 0 to 55% of a second promoter resin The stickiness of the group median.About 5% to about 35% by weight of a plasticizer and about 0% to about 20% by weight of a resin terminal block having a softening point lower than 125 < 198 > C, in which the components are 100% by weight of the composition, the viscosity of the composition is Equal to or less than 20000 MPa.S 120 < 198 > C and is applied at a temperature lower than 150 < 198 > C and the retention of the initial connection of the composition of elastic filaments is less about 60%. The elastic modulus G of the composition is higher than about 5000 PA module g \"viscous are higher than about 50pA and the value of delta tannin is between about 0.5 and about 60.Laminates, especially those used in disposable soft articles, and methods of producing such laminates are also described.The composition adevisa and \/ or laminates can be used in the production of a variety of end products such as a disposable diaper, napkin asnit\u00e1rio cushion, a bed, a bandage, a curtain of surgery, a tape, a label, a plastic blade, a blade tec. Ida, a sheet of paper, a cardboard, a book, a filter or a package.composições adesivas fundidas a quente, laminados, artigos e métodos de produção de laminado elástico. uma composição adevisa fundida a quente, que compreende uma mistura de componentes que inclui cerca de 10% até aproximadamente 40% em peso de um copolímetro de bloco ela
