ELASTOSIL® LR 3015/50 A/B

1 of 114 products in this brand
ELASTOSIL® LR 3015/50 A/B is a liquid silicone rubber. It is a paste-like, readily pigmentable, two-component compound with a short curing time. Its vulcanizates are noted for their high oil resistance. It is colored off-white and has moderate mechanical properties. Thanks to the excellent compression set, there is no need to post-cure technical parts.

Application Details

ELASTOSIL® LR 3015/50 A/B is particularly suitable for the economical production of large series of injection molded articles. Parts made from ELASTOSIL® LR 3015/50 A/B can generally be used for technical applications without postcuring, but do not comply with regulations concerning use in the pharmaceutical and food industry. Due to their high oil resistance, ELASTOSIL® LR 3015/50 A/B is mainly used to produce gaskets for automotive and other mechanical engineering applications.

Processing

ELASTOSIL® LR 3015/50 A/B is less abrasive than common liquid silicone rubbers with improved oil resistance. This increases the lifetime of molds, dies and machinery. 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 three days.
