- Application Details
- 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.
Processing
The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer.
