Synthetic rubber pressure-sensitive adhesive, pressure-sensitive adhesive sheet, and polishing member laminate
The invention provides a synthetic rubber pressure-sensitive adhesive which has excellent heat resistance and substrate adhesiveness, is capable of inhibiting offset, peeling or the like even in a high-temperature environment and is suitable for applications in a high-temperature environment, a pressure-sensitive adhesive sheet and a polishing member laminate. The synthetic rubber pressure-sensitive adhesive of the invention contains: a synthetic rubber (A) including a styrene-isoprene block copolymer, an adhesion-imparting resin (B), and a fatty acid ester (C) with a weight reduction rate of 1 wt % or less after being heated at 150° C. for 10 minutes. Based on 100 parts by weight of the synthetic rubber (A), the content of the adhesion-imparting resin (B) is set as α parts by weight to 60 parts by weight, and the content of the fatty acid ester (C) is set as 0.1 parts by weight to 10 parts by weight.
DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE TAPE
The invention relates to a method for peeling a pressure-sensitive adhesive tape including: a pressure-sensitive adhesive layer. The pressure-sensitive adhesive tape has a thickness greater than 150 μm and smaller than 1,500 μm, an elongation at break of 600% to 3,000%, and a stress at break of 2.5 to 80.0 MPa. According to the invention, the conformity and the adhesion with respect to an adherend, particularly, a hard adherend, are excellent, and excellent re-peeling properties are obtained, so that the pressure-sensitive adhesive tape can be stretched and peeled off in a horizontal direction, without necessity for embrittling the pressure-sensitive adhesive tape by heating or by using an organic solvent or the like or without remaining of the pressure-sensitive adhesive on the adherend, in a case of peeling the pressure-sensitive adhesive tape.
RADIATION STERILIZATION RESISTANT ADHESIVE
Provided is a radiation sterilization resistant adhesive agent layer capable of reducing or preventing a decrease in wettability of an adhesive after radiation sterilization treatment. The adhesive can be used with a medical implement, for example medical implements that are sterilized. The adhesive agent layer includes a (meth)acrylic polymer and a wettability stabilizer, and the wettability stabilizer is at least one selected from a rosin ester resin, a terpene phenol resin, and hydrides thereof.
TAPE OR SHEET FOR SKIN ATTACHMENT
A tape or sheet for sticking to skin, which includes a base material and an adhesive layer laminated on at least one surface of the base layer, wherein the adhesive layer contains an acrylic copolymer obtained by copolymerizing a monomer mixture including a (meth)acrylic acid alkyl ester monomer and an alkoxy group-containing ethylenically unsaturated monomer, a component that is liquid or paste-like at room temperature, and a tackifier, and wherein the tackifier includes a rosin ester.
PROPYLENE RANDOM COPOLYMER BASED HOT MELT ADHESIVE COMPOSITION
The present application relates to an adhesive composition comprising a polypropylene resin, a tackifying resin and a plasticizer resin having a superior balance of properties in regard of Brookfield viscosity and maximum probe tack. It further relates to an article comprising the adhesive composition and to a process for producing said article. The application also relates to the use of the adhesive composition in the preparation of an article.
