Ethylene glycol, antifreeze, is extremely toxic to dogs. It has a sweet taste and thus dogs will drink it. As little as 2 1/2 tablespoons can kill a medium-sized dog in 2–3 days. This type of poisoning is often fatal as dog owners do not know their pet has ingested the antifreeze. De-icing fluids can also contain ethylene glycol.
Silicone rubber is an elastomer 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 rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.
Silicone granulomas are a skin condition that occur as a reaction to liquid silicones, and are characterized by the formation of nodules. [1]: 46 Formation of a granuloma is a common tissue response to a range of foreign bodies. Silicone can be directly injected into tissue as part of a cosmetic procedure or it can leak from silicone implants.
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 ...
The silicone polymers are often made by reacting dimethyl dichlorosilane with water. [4] Linear dimethylpolysiloxane polymer reaction. Fillers such as acetic acid can provide a fast cure time, while oxides and nitrides can provide better thermal conductivity. Tack-free times are typically on the order of minutes, with cure times on the order of ...

Toxic gases – Gases which: are known to be so toxic or corrosive to humans as to pose a hazard to health; or; are presumed to be toxic or corrosive to humans because they have an LC 50 value equal to or less than 5000 ml/m 3 (ppm). e.g. hydrogen cyanide. Division 2.3
Silicone grease is soluble in organic solvents such as toluene, xylene, mineral spirits, and chlorinated hydrocarbons. It is insoluble in methanol, ethanol, and water. [2] Thermal grease often consists of a silicone-grease base, along with added thermally conductive fillers. It is used for heat-transfer abilities, rather than friction reduction.
