Silicone Rubber Density Kg M3

Epdm is an m class rubber under astm standard d 1418.

Silicone rubber density kg m3.

For comparison water has a specific gravity of. At 25 c 77 f or 298 15k at standard atmospheric pressure in imperial or us customary measurement system the density is equal to 145 457 pound per cubic foot lb ft or 1 35 ounce per cubic inch oz inch. The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene. It is a hard brittle crystalline solid with a blue grey metallic lustre and is a tetravalent metalloid and semiconductor it is a member of group 14 in the periodic table.

To appropriately fit an application with the ideal type of neoprene durometer must be taken into account. Density of aqueous solutions of organic acids changes in density of aqueous solutions with changes in concentration at 20 c. Silicon weighs 2 33 gram per cubic centimeter or 2 330 kilogram per cubic meter i e. Density of acetic acid citric acid formic acid d lactic acid oxalic acid and trichloroacetic acid in water.

It is relatively unreactive. Main applications are flexible seals o rings etc. The silicone properties that are listed below are for our most popular silicone 70 durometer 70a rubber material. Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications.

165 c x 10 min press cure 200 c x 4 h post cure 1 standard addition quantity is the quantity of curing agent added to 100 parts compound. Silicones are polymers with a si o si backbone. Silicon is a chemical element with the symbol si and atomic number 14. That s 60 to 80 lbs per cubic foot.

Because of its high chemical affinity for oxygen it was not. Key properties include thermal stability chemical stability electrical insulation and low toxicity. If you need properties that are different than the ones in the chart below please take a look at our other popular rubber material specifications otherwise we can compound and reformulate the silicone rubber specifications to. Durometer is the measurement of a particular neoprene sheet rubber s hardness or softness.

2 linear shrinkage values differ according to the curing agent used. Density of inorganic sodium salts in water is plotted as function of wt mol kg water and mol l solution. 0 968 to 1 29 grams per cubic centimeter for the silicone most people think of implants.
