A radio frequency shield door system is provided. The radio frequency shield door system provides an effective RF and electromagnetic seal between a door and the perimeter of the doorway through a continuous interface of conductive or magnetic material between peripheral sealing surface of the door and a perimeter frame of the doorway. The perimeter frame may provide spring-loaded contact rails electrically or magnetically coupled thereto so that when the door is in a closed configuration a RF seal is formed between the interfacing sealing surface and contract rails, yet the door is still readably between an open configuration and closed configuration.

An astragal is described having a housing and a weather-strip extending along a length of the housing. An end cap is mounted to the housing. The end cap has a bottom wall positioned substantially horizontally along the bottom end of the housing. The bottom wall has an interior edge, an exterior edge opposite the interior edge, an upper surface, and a lower surface opposite the upper surface. At least one projection extends upwardly from the upper surface at a location along the upper surface closer to the interior edge than the exterior edge. The projection sized and positioned to project into the weather-strip and at least partially seal with a cavity opening at a lower end of the weather-strip.

A coupling part of a weather strip is fixed between a first anchoring part and a second anchoring part on an outer peripheral part of a sash of a door. A hollow seal member and an outer lip are integrally formed with the coupling part and make elastic contact with a second surface and a first surface of a door opening edge of a body panel, respectively, when the door is in the closed position. The weather strip is fixed to the sash only by fixing the coupling part. A pillar part couples the coupling part with the hollow seal member. A body seal lip is provided on the hollow seal member and makes elastic contact with the door opening edge when the door is in the closed position.

A gasket for a refrigerator door is provided. The gasket includes a body configured to be arranged between a main body of a refrigerator and a refrigerator door, and a magnet inserted to the body and arranged to be attached to or detached from the main body of the refrigerator. The body includes, by weight % (wt %), about 30 to 60% of thermoplastic resin, about 20 to 40% of plasticizer, about 3 to 30% of filler, and one or more other additives. The filler is provided with one or more hollow particles or a porous material having a diameter of about 1 to 100 μm, the filler having a heat conductivity of about 0.0001 to 0.2 W/m.Math.K.
