Natural or synthetic rubber
For a rough definition of natural rubber or synthetic rubber, natural rubber (NR) is a material produced by nature, all synthetically produced elastomeric materials, is a model in terms of its structure. NR has a very high tensile strength, especially in soft elastomer qualities, a high elasticity, flexibility at low temperatures and excellent dynamic properties, which are hardly ever achieved by synthetic elastomers in this combination and therefore make NR indispensable for some applications, especially for vibration insulation systems, even today.
When designing elastomer springs, dynamic hardening must also be taken into account. With low-damping elastomer materials such as NR, it can generally be neglected. With highly damping compounds, the dynamic spring stiffness can be several times higher than the static one.
If, however, extreme demands are made on a product with regard to certain resistances, including oxidation and damping properties, it is essential to switch to synthetic rubber.
