ELASTOSIL® LR 3011/50 FR A/B

1 of 114 products in this brand
ELASTOSIL® LR 3011/50 FR A/B is a liquid silicone rubber. It is a paste-like, low-inflammable, two-component compound. The excellent flame retardancy is confirmed by UL94-V0 listings at 0.75 mm and 3 mm thickness. Good heat resistance, low compression set, short curing times, and non-abrasive behavior in the LIM process are further benefits of this material.

Application Details

This grade is especially designed for economical manufacturing of flame retardant technical articles/parts by Liquid Injection Molding process.

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.
