Its main feature is the springback, or elasticity. You can stretch a rubber strip till it reaches a length much greater than its original one, without breaking; then letting it go it returns to the original shape and length. The rubber materials are called “ELASTOMERS”. Elastomers have many features: almost all have a good impermeability to water and air and abrasion resistance and tensile strength. There are rubbers that can withstand temperatures higher than 200°C and are not eaten by most aggressive chemical products. Other special qualities allow to preserve and maintain their elasticity to about -100°C
