What is the density of EPDM?
EPDM, Ethylene Propylene Diene Monomer, is a synthetic rubber elastomer. It is an “M” class rubber based on its classification in ASTM standard D-1418….Common Properties of EPDM.
|PROPERTIES||ASTM TEST METHOD||COMMON VALUES AND RANGES|
|Density (g/cm3)||ASTM D 790||1.10|
|Tensile strength, psi||D412||2523|
What is ethylene, propylene used for?
The principal uses of EPM are in automobile parts and as an impact modifier for polypropylene. EPDM is employed in flexible seals for automobiles, wire and cable insulation, weather stripping, tire sidewalls, hoses, and roofing film.
What is the density of nitrile rubber?
around 1.00 g/cm3
Properties of Nitrile (NBR) Rubber
|Hardness, Shore A||30 – 90|
|Tensile failure stress, ultimate||500 – 2500 PSI|
|Elongation after fracture in %||600% maximum|
|Density||Can be compounded around 1.00 g/cm3|
What is the density of rubber?
rubber and the known density of rhombic sulphur. sheet rubber varied from 0.9100 to 0.9126 with an average value of 0.9112. a density of 0.916.
Which is better nitrile or EPDM?
Although EPDM and nitrile are both synthetic rubbers, they are not the same material as EPDM is better resistant to outdoor environments than nitrile, and nitrile is better resistant to oils and greases than EPDM.
Is Buna-N the same as EPDM?
EPDM has specific resistence to bases, steam, phosphate ester hydraulic fluids, weathering and sunlight, glycol brake fluids (DOT 3, 4, 5.1), cleaning agents, ketones, brake fluids, some acids and steam <300ºF….EPDM (EP, EPR, Ethylene-Propylene Rubber)
|Short Name||Buna-N: Buna-N||EPDM: EPDM|
What is the difference between EPR and EPDM?
EPR (aka EPM, EP copolymer) contains only ethylene and propylene monomers. EPDM (aka EPT, EP terpolymer) is composed of ethylene, propylene, and a third monomer called a diene (three different dienes are in common use today, but discussing their differences gets extremely dry and technical.)
