Specific weight of rubber, properties, types and value table
Rubber is a natural or synthetic elastomer used as the basis for producing rubber compounds and many rubber products. Natural rubber is obtained from the latex of rubber-bearing plants, while synthetic types are produced chemically from monomers. The material is valued for its high elasticity, ability to recover its shape after deformation, and good resistance to water.
In industry, rubber is used not only as a raw material on its own but also as a component of rubber mixtures. Fillers, plasticizers, vulcanizing agents and other additives are added to such mixtures to obtain a material with the required hardness, strength, frost resistance, oil resistance or wear resistance.
Table of rubber specific weight
The weight of rubber depends on its composition, grade, amount of additives and measurement conditions. For reference calculations, a specific weight range from 0.91 to 0.92 g/cm³ is usually used. This means that 1 m³ of rubber weighs approximately 910 to 920 kg.
The table below helps quickly determine the approximate weight of rubber when calculating volume and mass.
| Material | Specific weight, g/cm³ | Weight of 1 m³, kg |
| Rubber | From 0.91 to 0.92 | From 910 to 920 |
Properties and types of rubber
Rubbers are commonly divided into general-purpose and special-purpose materials. General-purpose rubbers are used where elasticity, strength and versatility of the rubber compound are important. This group includes butadiene, polybutadiene, butyl, ethylene-propylene, EPDM and polyisoprene materials.
Special-purpose rubbers are used to obtain rubber products with specific properties, such as increased oil resistance, frost resistance, wear resistance, resistance to aggressive media or improved adhesion. These materials include chloroprene, nitrile-butadiene, urethane, halogenated, polysulfide and silicone rubbers.
The properties of a particular rubber determine its field of application. When products are manufactured, the rubber compound recipe is selected with regard to the type of rubber, fillers, plasticizers and processing additives. As a result, one base material can be used to obtain products with different performance characteristics.
The main properties of rubber include:
- high elasticity and the ability to recover shape after deformation;
- impermeability to water and many gases;
- the ability to change hardness, strength and resistance through the composition of the rubber compound;
- suitability for producing tires, seals, belts, gaskets, footwear materials and other rubber products.
Frequently Asked Questions
How much does 1 m³ of rubber weigh?
For reference calculations, the article uses 910-920 kg/m³, but the actual value depends on rubber type and compound formulation.
Why does vulcanized rubber density differ from raw rubber?
Rubber compounds contain fillers, plasticizers, vulcanizing agents and additives, so their density can differ significantly from base rubber.
How should a value be chosen for product calculation?
Use the specific rubber or compound type. For exact calculations, take the material datasheet.
