- Application Details
These grades are particularly suitable for the economical production of large series of injection-molded articles. Parts made from ELASTOSIL® LR 3040/40 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. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least one day. The vulcanization (t90 value) is 20 to 40% shorter than of products in the ELASTOSIL® LR 3043 series. This consequently leads to a decrease in cycle times and thus to cost savings, depending on the injection-molded articles.
