1 of 114 products in this brand
ELASTOSIL® LR 3066/40 A/B is a liquid silicone rubber from the ELASTOSIL® LR 3066 series. It is a paste-like, easily pigmentable, two-component compound with a short curing time and a low coefficient of friction. When compared to the ELASTOSIL® LR 3003 grade, the coefficient of friction is reduced by 50-70%. The vulcanizates of this product are renowned for their high transparency as well as their exceptional mechanical and electrical properties.

Application Details

These grades are particularly suitable for the economical production of large series of injection-molded articles. Provided appropriate processing, EL LR 3066/40 A/B parts can be used for food contact applications in accordance with the Recommendation "XV. Silicones" of the BfR and FDA 21 CFR § 177.2600 under observance of any given limitations on extractable and volatile substances.

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 three days.
