What is the density of nitrile rubber?
around 1.00 g/cm3
Properties of Nitrile (NBR) Rubber
| Property | Typical Value |
| 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 are the mechanical properties of nitrile rubber?
Nitrile-butadiene rubber (NBR) exhibits a relatively low density, moderate tensile strength, and high oil resistance [1,2]. A higher acrylonitrile content in NBR leads to higher heat resistance, gas impermeability, and tensile strength; however, it also decreases elasticity and frost resistance [3].
What is NBR hardness?
Durometer or Hardness Range: 20 – 95 Shore A. Tensile Strength Range: 200 – 3,500 PSI. Elongation (Range %): 350% – 650% Abrasion Resistance: Good to Excellent.
What is the density of rubber?
Soft rubber for example has a density of 69 lb/foot cubed, while hard rubber has a density of 74 lb/foot cubed. Very soft rubber can have a rubber density of 57-58 lb/foot cubed, so there’s quite some difference within the kind of rubber parts and O-rings.
What is the density of natural rubber?
0.91 g/cm3
Introduction
| Glass transition temperature | ∼ − 71 °C |
|---|---|
| Mass density (amorphous phase) | 0.91 g/cm3 |
| Mass density (crystalline phase) | 1.0 g/cm3 |
| Molecular weight of raw natural rubber | ∼1.5 × 106 g mol−1 |
| Strain at break | >500 % |
What are the properties of NBR rubber?
It has the highest thermal conductivity and a moderately high tensile strength among rubber materials. The graph bars on the material properties cards below compare NBR rubber to other rubber materials (top) and the entire database (bottom).
How do the graph bars compare NBR rubber to other materials?
The graph bars on the material properties cards below compare NBR rubber to other rubber materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set.
What is the resistance of NBR to oil?
NBR has good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkalines. An important factor in the properties of NBR is the ratio of acrylonitrile groups to butadiene groups in the polymer backbone, referred to as the ACN content.
What is the best nitrile content for NBR?
High Nitrile: > 45 % acrylonitrile Medium Nitrile: 30 – 45% Low Nitrile: < 30% The best overall balance for most applications is a medium nitrile content. COMMERCIAL NBR Elastomers
