Fight against press ganging ketone rubber o-rings, refers to the rubber o-rings, butanone, is made of the distribution of resistance to butanone rubber material production, usually choose fluorine rubber material in the majority.
Butyl ketone is a kind of colorless transparent liquid, with similar acetone smell, volatile, can with ethanol, ethyl ether, benzene, chloroform, oil miscibility.The water soluble in 4, but lower solubility at higher temperatures.11.3% can form azeotrope with water (water), azeotropic temperature 73.4 ºC (including butanone 88.7%).Relative density (d204) 0.805.Freezing point - 86 ºC.Boiling point 79.6 ºC.Refractive index (n15D) 1.3814.Flash point 1.1 ºC.Low toxicity, median lethal dose (rats, through the mouth) 3300 mg/kG.Flammable, can form explosive mixtures with air and steam explosion limit of 1.81% ~ 1.81% (volume).High concentrations of vapour has a narcotic.
Fight against press ganging ketone rubber o-rings, mainly is the resistance to corrosion of butanone, does not have the resistance to butanone rubber products, products will direct expansion or dissolved, and the resistance to butanone rubber o-rings wouldn't. Because of the harm of the butanone, therefore butanone rubber ring is applied more and more resistant, welcome the masses of customer calls to sample.
