A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

The invention relates to a laminate comprising a first layer and a second layer directly covering the first layer, the first layer being a layer of a silicone rubber composition comprising a micrometric silicone powder and a mixture of crosslinkable organopolysiloxanes, the second layer being a layer of a silicone rubber composition comprising a hydrophobic silica and a mixture of crosslinkable organopolysiloxanes, the first layer and the second layer being crosslinked. The laminate, in particular when it is used as a coating for the outer surface of an expandable bladder for a tyre curing mould, makes it possible to eliminate moulding defects on the inner liner of the tyre.

A laminate body including a base material and a flat silicone sealing layer adhered thereto, generally without any voids, is provided. Also provided is a curable hot melt silicone composition layer with a particular curable hot melt silicone composition, providing a laminate body that does not readily cause stress on a substrate after the curable hot melt silicone composition is cured. A laminate body comprises a base material, and a curable hot melt silicone composition layer in contact with the base material. The curable hot melt silicone composition includes an organopolysiloxane resin containing siloxane units selected from a group containing T units or Q units making up at least 20 mol % or more of all siloxane units. The curable hot melt silicone composition generally has a melt viscosity as measured using a flow tester at a pressure of 2.5 MPa and at 100° C. of 5,000 Pa.Math.s or less.
