Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Animation of heat-shrink tubing, before and after shrinking. Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical wiring.
Foam fixer pump used to draw silicone foam individual components, then mix them at the nozzle and dispense into desired location. Silicone foam having been dispensed into hole in a wall, above a door. Silicone foam is a synthetic rubber product used in gasketing, sheets and firestops. It is available in solid, cured form as well as in ...
A flexible coating of an insulator is often applied to electric wire and cable; this assembly is called insulated wire. Wires sometimes don't use an insulating coating, just air, when a solid (e.g. plastic) coating may be impractical. Wires that touch each other produce cross connections, short circuits, and fire hazards.
Rigid panel insulation, also known as continuous insulation [13] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
[1] Electricians may use various colors of tape to insulate wire and to indicate the voltage level and phase of the wire (colored tape sometimes is called "phasing tape"). When wires are phased, a ring of tape is placed on each end near the termination so that the purpose of the wire is obvious. The following table(s) describe the use of ...
In this case, the plastic at the substrate surface is dissolved by the solvent contained in the adhesive. This leads to an increased mobility of the plastic's polymer chains, which in turn allows penetration by those of the adhesive. Ultimately, additional interactions occur between the polymer chains of the adhesive and the substrate.
