| Liquid silicone rubbers of the ELASTOSIL® LR 3020 series are paste-like, easily-pigmentable two-component compounds with short curing times. Their vulcanizates are noted for excellent steam resistance. Properties: The products can be used within a temperature range of - 55 °C to + 210 °C. The addition of heat stabilizers at service temperatures of more than 180 °C is recommended. Further information to improve the heat stability by use of specific ELASTOSIL® FL Color Pastes can be obtained from the Technical Information Sheet "ELASTOSIL® FL Color Pastes". Application: These grades are particularly suitable for the economical production of large series of injection-molded articles. Although most silicone rubbers show good resistance to boiling water, they degrade rapidly when subjected to superheated steam at temperatures of 150 °C and above (corresponding to 6 bar pressure). ELASTOSIL® LR 3020/60 A/B shows significantly improved performance under such conditions, especially with respect to the long term compression set. Parts made from ELASTOSIL® LR 3020/60 A/B can be used for technical applications. These articles are also suitable for use in conjunction with foodstuffs. Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances. Information provided by Wacker. |
