A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x% by weight of at least one natural rubber component, y% by weight of at least one polyacrylate component, v% by weight of at least one adhesive resin component and w% by weight of additives, where 10≦×x≦80, 10≦y

摘要:
Self-adhesive consisting of a mixture having at least one tackifier resin, expanded polymeric microbeads and a polymer blend made up of thermoplastic and/or non-thermoplastic elastomers with at least one vinylaromatic block copolymer containing a fraction of more than 30% by weight of 1,2-linked diene in the elastomer block.
摘要:
A process is presented for the preparation of a high-cohesion non-thermoplastic pressure-sensitive adhesive (PSA) on the basis of elastomers, in which neither a solvent nor thermoplastic additives are used and yet thermal breakdown during compounding is kept low. This is achieved through the addition of a vaporizable process agent which is introduced into the adhesive after the constituents have been premixed and which undergoes flash vaporization therein, thereby quenching the adhesive. Furthermore, the use of water to cool the adhesive is proposed, and the high-cohesion PSA thus produced, and also a pressure-sensitive adhesive tape with an adhesive of this kind, are presented.
摘要:
The invention relates to a process for preparing a foamed polymer composition using expandable hollow microbeads, wherein, in a first process strand, first starting materials, which include at least the predominant portion of the polymer or polymers to be used, are mixed and degassed to give a premix, whereafter this premix is subjected to a pressure such that the pairing of this pressure with the temperature of the premix is below the pressure and temperature pairing that is critical for triggering the expansion of the hollow microbeads to be used, wherein, in a second process strand, second starting materials, including the hollow microbeads to be used, are degassed, whereafter the second starting materials treated in the second process strand are added to the premix prepared in the first process strand, whereafter the second starting materials are mixed with the premix.
