Description
Natural rubber (CAS 9006-04-6) is a biopolymer derived from the latex of Hevea brasiliensis, commercially available under trade designations including VS 65, WB 60, AMA 7, V 145, and UNITEX. It consists predominantly of cis-1,4-polyisoprene chains and is classified within the Polymers and Resins category.
In rubber and tire manufacturing, natural rubber provides the high tensile strength and vibration damping required for passenger and commercial vehicle tyres, conveyor belts, and engine mounts. Its high electrical resistivity makes it suitable for insulating components in automotive and aerospace wiring assemblies, where consistent performance under mechanical stress is critical.
Natural rubber is supplied in solid grades including ribbed smoked sheet, technically specified rubber, and crepe, conforming to ISO 2000 and ASTM D2227 standards where applicable. It falls under REACH regulation requirements for supply within the EU. Packaging formats typically include bales of approximately 33 kg.

Physical Properties
| Density | 0.906-0.916 g/cm³ @ Temp: 20 °C |
| Appearance | High tensile strength; relatively low per- manent set; insensitive to temperature changes. Attacked by heat, atmospheric oxygen, ozone, hydrocarbons, and unsaturated fats and oils. Insol- uble in acetone. Permeable to gases; supports combustion; abrasion resistance poor unless com- pounded with carbon black; dissipates vibration shock; high electrical resistivity. |
| Form | milky fluid; solid. |
