ELASTOSIL® LR 3005/30 A/B

ELASTOSIL® LR 3005/30 A/B is a liquid silicone rubber of the ELASTOSIL® LR 3005 series. It is a paste-like, easily pigmentable, two-component compound with short curing times. The vulcanizates of this product are renowned for their high transparency as well as their exceptional mechanical and electrical properties. Due to the excellent compression set, there is no need to post-cure technical parts.

Application Details

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 molded articles. They can generally be used for technical applications without post-curing, but do not comply with regulations in the pharmaceutical and food industry.

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 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-molded articles.
