ELASTOSIL® LR 3015/70 A/B
ELASTOSIL® LR 3015/70 A/B liquid silicone rubber is a pastelike, readily pigmentable two-component compound with short curing time. Its vulcanizates are noted for their high oil resistance. They are colored off white and have moderate mechanical properties. Thanks to the excellent compression set, there is no need to post-cure technical parts.
ELASTOSIL® LR 3015/70 offers improved oil resistance, especially low compression set in contact with engine oils.
ELASTOSIL® LR 3015/70 A/B的特殊性能
ELASTOSIL® LR 3015/70 A/B is particularly suitable for the economical production of large series of injection molded articles. Parts made from ELASTOSIL® LR 3015/70 A/B can generally be used for technical applications without post-curing, but do not comply with regulations concerning use in the pharmaceutical and food industry. Due to their high oil resistance, ELASTOSIL® LR 3015/70 A/B is mainly used to produce gaskets for automotive and other mechanical engineering applications.
ELASTOSIL® LR 3015/70 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.
For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".
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.
