Abstract:
A silicone release laminate formed by a support layer (11) with a silicone release layer (13). A separate pressure-sensitive silicone adhesive layer (12) may be on the same side of the support as the release layer, or on opposite sides of the support. The force required to separate the adhesive from the release layer is less than about 100 grams (3.3 oz.) per inch, and preferably less than 50 grams (1.7 oz.) per inch. The release layer is formed from one or more organopolysiloxanes having a viscosity below 1000 centipoises, and preferably below about 600 centipoises, with a high degree of cross-linking. The organopolysiloxanes may be produced directly by hydrolysis of organo-substituted halosiloxanes and depolymerization; or by hydration of higher molecular weight organopolysiloxanes and heat treatment to produce lower weight constituents.
Abstract:
A laminate of dielectric materials is disclosed for use in protecting an electronic device. The laminate includes at least one layer of a polymeric material having an active material dispersed within the polymeric material and having a first thickness. The active material is responsive to external electric fields such that a higher voltage external electric field may be applied to one side of the laminate without any voltage passing through the laminate than a maximum voltage that could be applied to the laminate without passing through the laminate when the active material is not present within the polymeric material having the first thickness.
