ELASTOSIL® R 402/60 US

ELASTOSIL® R 402/60 US is a high-consistency silicone rubber (HCR) that is known for its high transparency and good mechanical properties. This product has a high green strength, making it suitable for the production of complex extruded profiles. Its vulcanizing characteristics allow for short cycle times in the manufacturing of rubber moldings through compression, transfer, and injection molding processes. The post-cured vulcanizates of this product are suitable for applications in the health care and food handling industries. ELASTOSIL® R 402/60 US is formulated with ingredients that are suitable for food contact applications, complying with Title 21 "Food and Drugs," Part 177.2600, which regulates rubber articles intended for repeated use. However, it is the responsibility of the user to ensure compliance with this regulation due to its limitations.
