A polyurethane foam may include an isocyanate polymer component and a polyol component. The polyol component may include a polyol having a molecular weight of at least about 500 kg/mol and not greater than about 6000 kg/mol. The polyurethane foam may have an elongation of at least about 500%. The polyurethane foam may further have a density of at least about 250 g/L and a tensile strength of not greater than about 1000 kPa.

The present invention relates to a redetachable adhesive tape having a carrier based on a crosslinked polyurethane and an adhesive layer based on vinylaromatic block copolymer, to a method for producing the adhesive tape and the use of the adhesive tape in the production of electronic components.

A double-sided adhesive tape is provided for bonding two or more adherends. The double-sided adhesive tape has satisfactory rollability, excellent reworkability after cleavage, and excellent shear holding characteristics at high temperatures. The double-sided adhesive tape includes a foam base, a resin layer (A1) disposed in direct contact with one surface of the foam base, an adhesive layer (B1) disposed on A1 on a side opposite to the foam base, a resin layer (A2) disposed in direct contact with another surface of the foam base, and an adhesive layer (B2) disposed on A2 on a side opposite to the foam base. A1 and A2 are each formed of a crosslinked product of a composition containing a resin having a hydroxy group and a compound reacting with the hydroxy group, and the tensile modulus of each of A1 and A2 is 50 MPa or more and 1000 MPa or less.

Cure in place pressure sensitive adhesive compositions are described that comprise one or more of a bodying component, a structural diluent, a radical diluent as well as additives such as crosslinkers, external catalysts, photoinitiators and stabilizers/process aids. The bodying component can be acrylic or non-acrylic.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.
