A thermal insulation material for a battery pack includes: a thermal insulation layer; and a first base material and a second base material that are arranged with the thermal insulation layer interposed therebetween. The thermal insulation layer contains a porous structure in which a plurality of particles is connected to form a skeleton, reinforcing fibers, and metal oxide nanoparticles serving as a binder, the porous structure having pores inside and having hydrophobic sites at least on a surface of the porous structure out of the surface and inside of the porous structure, and a percentage mass loss of the thermal insulation layer in thermogravimetric analysis in which the thermal insulation layer is held at 500° C. for 30 minutes is 10% or less.

Thermal insulation material for battery pack and battery pack

A heat insulating material () includes a heat insulating layer () which has a porous structural body, a reinforcing fiber, and nanoparticles of a metal oxide used as a binder, wherein the porous structural body has a skeleton formed by connecting a plurality of particles, has pores inside, and has a hydrophobic portion on at least one surface between a surface and an inside of the porous structural body. The heat insulating layer () has a mass loss rate of 10% or less in thermogravimetric analysis held at 500&#xb0; C. for 30 minutes.

Heat insulating material and manufacturing method thereof

A fluid device composite member includes: a silicone member that includes a body part which is made of silicone and which has a flow-path-defining section for defining a flow path on one surface of the body part, and that includes barrier layer having hydrophilicity or hydrophobicity disposed in at least a portion of the flow-path-defining section; and a resin substrate disposed on another surface of the body part opposite to the one surface. This method for manufacturing the fluid device composite member includes a layered body manufacturing step in which a liquid silicone material is placed on a surface of the resin substrate, and the liquid silicone material is cured at a temperature of 100&#xb0; C. or less to obtain a layered body in which a silicone cured product is bonded to the resin substrate.

Method for manufacturing fluid device composite member

A blade memberis used for removal of residual tonerremaining on a surface of a counterpart memberin an image forming device employing an electrophotographic system, by sliding contact with the counterpart member. The blade memberincludes a blade bodymade of a polyurethane rubber using diphenylmethane diisocyanate and a polyester polyol as main raw materials, and a filmthat covers at least a surface of a sliding contact portion of the blade bodyto contact with the counterpart member. The polyurethane rubber has an international rubber hardness degree of 65 to 85 IRHD, a tan &#x3b4; peak temperature of 8&#xb0; C. or lower, and a tan &#x3b4; peak value of 1.1 or less. The filmcontains a hydrocarbon polymer as a main component.
