TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The silicone pressure sensitive adhesive mass is based on condensation-crosslinking silicone with the following components: (a) a hydroxy-functionalized organopolysiloxane having at least one diorganosiloxane unit; (b) an organopolysiloxane resin of formula (((R1)3SiO1/2)x(SiO4/2)1); (c) optionally a stabilizer; and (d) optionally an initiator. The silicone pressure sensitive adhesive mass is compounded with 0.2-5 wt.% of peroxo initiator, preferably benzoyl peroxide. The silicone pressure sensitive adhesive mass is based on addition-crosslinking silicone with the following components: (e) an organopolysiloxane exhibiting at least one diorganosiloxane unit and at least two silicone-bonded alkenyl groups in each molecule; the component (b); (g) an organopolysiloxane comprising at least two silicone-bonded hydrogen atoms in each molecule, where the organopolysiloxane is free from olefinic double bonds and the amount of organopolysiloxane is selected in such a way that 0.01-10 moles of silicone-bonded hydrogen atoms per mole of total alkenyl groups of components (a), (b) and (e) are present; an metallo-organo catalyst of 10th group of the periodic table of elements; and (i) optionally an inhibitor. The ratio of ((R1)3SiO1/2)x-units (M units) to (SiO4/2)1-units (Q-units) is 0.5-1.2. The average molecular weight of the organopolysiloxane resin (MQ resin) is 500-100000 (preferably 1000-25000) g/mole. The weight ratio of organopolysiloxane to organopolysiloxane resin is 20:80-80:20 (preferably 30:70-60:40). The silicone foam material layer has a closed cell silicone foam with a density of 180-500 kg/m3. The silicone foam exhibits UV-resistance. The silicone foam material layer has a thickness of 0.5-1.5 (preferably 0.8-1.1) mm.R1 = monovalent hydrocarbon (optionally substituted), H or OH; andx = 0.5-1.2.Preferred Process: The silicone pressure sensitive adhesive mass is crosslinked with actinic radiation, preferably electron beams at a dose of 10 kilogray.
