ELASTOSIL® LR 3004/30 A/B
Liquid silicone rubbers of the ELASTOSIL® LR 3004 series are paste-like, easily-pigmentable two-component compounds with very short curing times. Their vulcanizates are noted for their high transparency and excellent mechanical and electrical properties.
Eigenschaften
Narrow Shore hardness range from 28 to 34 Shore A (31 ± 3 Shore A). This product 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® Color Pastes FL can be obtained from the Technical Information Sheet "ELASTOSIL® Color Pastes FL".

Datenblätter
These grades are particularly suitable for the economical production of large series of injection-moulded articles. Parts made from ELASTOSIL® LR 3004 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.
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.
For detailed information refer to our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".
The vulcanization (t90 value) is 20 to 50% shorter than of products in the ELASTOSIL® LR 3003 series. This consequently leads to a decrease in cycle times and thus to cost savings, depending on the injection-moulded articles.
Verpackung / Gebinde
This product is available in 20 kg pail and 200 kg drum kits.
Lagerung
Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
