A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld.

A method of making a dispenser includes: mixing a plurality of materials, the materials including plant fiber, vegetable gum, starch, a toughening agent, and a dispersing agent; utilizing a granulator to form the mixture of the plant fiber, the vegetable gum, the starch, the toughening agent, and the dispersing agent into pellets; and forming a dispenser by moving the pellets into a processing machine; wherein the processing machine melts the pellets and disposes the melted material into a cavity configured as a forming mold, and after cooling the dispenser is obtained.

A composite structure with high pressure resistance that is suitable for a flow channel is produced by reducing the number of components while maintaining the excellent chemical resistance and high stress tolerance inherent to a glass substrate and a resin substrate. A glass substrate surface is modified with a hydrolyzable silicon compound, and the glass substrate is brought into contact with the resin substrate. Subsequently, the contact surface between the glass substrate and the resin substrate is heated to a temperature from the glass transition temperature to the pyrolysis temperature of the resin substrate, eliminating gaps between the glass substrate and the resin substrate to bring them into close contact with each other, and causing chemical binding or anchor effects between the glass substrate and the resin substrate via the hydrolyzable silicon compound. Thus, the glass substrate and the resin substrate are firmly fixed to each other.

To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.

Provided is a syringe gasket including a first member, and a second member connected to the first member and coupled to a plunger rod of a syringe. The first member includes a top face contacting with the liquid, and a first side circumferential face that faces an inner circumferential face of a barrel of the syringe. The first side circumferential face has, at an end portion thereof close to the second member, a ring-like trimmed face. An inert film is laminated on the top face and the portion of the first side circumferential face other than the ring-like trimmed face. The second member includes a second side circumferential face that faces the inner circumferential face of the barrel, and a ring-like protruding portion that projects outward in the radial direction from the second side circumferential face. The ring-like protruding portion at least partially covers the ring-like trimmed face.
