Silicone (formally called polymerized siloxane or polysiloxane) identifies any one of a number of polymers containing alternate silicon and oxygen atoms, whose properties are determined by the organic groups mounted on the silicon atoms. Silicone is fluid, resinous, rubbery, extremely stable in high temperatures, and water-repellent, making them suitable for use as adhesives, lubricants, hydraulic oils and insulation in a wide array of fields.
One of the key elements of silicone is its ability to maintain it’s mechanical properties over a wide selection Bento lunch box of temperatures, -80° F – 400° F (60° C – 205° C) and sometimes normality could be sustained in an even broader range of temperatures.
Silicone is usually mistakenly called “silicon” ;.Although silicones contain silicon atoms, they are not made up exclusively of silicon, and have different physical characteristics from the element silicon.
Silicone gaskets and pads can be purchased in open cell foams, closed cell sponges, various durometer solids, and is readily molded in a wide variety of colors. There are high tear strength silicones, reinforced silicones, electrically conductive silicones, and thermally conductive silicones.
There are silicone foams which can be UL94-V0 rated which is commonly required in the transit and electronic sectors. It performs well in compression set tests, and silicone can also be naturally UV resistant which makes it suitable for numerous outdoor applications.
Extreme temperature resistance, stability with extreme environmental and chemical stress, and durability are some of the reasons silicone benefits aviation and aerospace. Silicone rubber sealants are used to fasten interior and exterior doors, windows and paneling. Fluid resistance makes silicone suitable for fuel control diaphragms, hydraulic lines and cable clamp blocks. Silicone rubber keypads are even used in computers in the world and in space.
Silicone sealants are commonly used to seal gaps, joints, and crevices in buildings being constructed or renovated. Both professional and retail grade silicones are abundantly designed for this purpose. These one-part silicone sealants cure by absorbing atmospheric moisture, which supports in the professional installation. A moistened finger or damp cloth is all that is needed to apply, and many do-it-yourselfers typically use this process to apply silicone caulking. Similar methods work for urethane caulking, the greatest competitor of silicone caulking.
Silicone demand in the US will grow 4.7 percent annually through 2010, driven by performance and environmental advantages over acrylic, polyurethane, and rubber. Silicone fluids have, and will continue to have the highest demand. Demand for silicone gels will grow faster predicated on renewed growth in the electronics sector.
Silicone gels are necessary to the electronics sector, where highly specialized applications demand greater demands on the sealing materials. Silicone rubber is used to insulate, seal and protect circuits, engine gaskets, control unit gaskets, electronic encapsulation, and special elements for decoupling noise.
