ELASTOSIL® LR 3005/60 A/B
Liquid silicone rubber of the ELASTOSIL® LR 3005 series are a paste-like, easily-pigmentable twocomponent compounds with extremely short curing times. The vulcanizates are noted for their excellent mechanical and electrical properties. Due to the excellent compression set, there is no need to post-cure technical parts.
Narrow Shore hardness range from 57 to 63 Shore A (60 ± 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".
Spezifische Merkmale von ELASTOSIL® LR 3005/60 A/B
- Niedriger Druckverformungsrest ohne zu tempern

These grades are particularly suitable for the economical production of large series of injection-molded articles.
Parts made from ELASTOSIL® LR 3005 are particularly suitable for the economical production of large series of injection moulded articles. They can generally be used for technical applications without post-curing, but do not comply with regulations in the pharmaceutical and food industry.
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 days.
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.
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.
