Momentive Self-Bonding LSR Solutions For Healthcare
What is Self-Bonding Liquid Silicone Rubber (LSR)?
Momentive performance materials are the global leader in silicones and elastomers, providing outstanding solutions for many industries and applications. Momentive Liquid Silicone Rubber (LSR) is a two-component versatile class of pumpable silicone elastomers that can be molded and cured with fast cycle times and at elevated temperatures. Momentive offers a broad range of self-bonding LSR products that can be molded into precise shapes and dimensions, maintaining their flexibility and resistance in injection molding applications.
Momentive Liquid Silicone Rubber In Health Care Applications:
Healthcare silicone elastomers must encompass a particular set of characteristics from purity, clarity, and durability. Momentive offers a range of LSR products that enable the production of a broad range of disposable and reusable medical devices and supplies. It meets regulatory compliance, biocompatibility, and withstands repeated sterilization processes. Furthermore, Momentive performance materials exhibit outstanding stability properties when exposed to a diverse range of temperature conditions.
They also offer primer-less adhesion without post-curing to various substrates. Momentive Liquid Silicone Rubber (LSR) solutions also enable the manufacturing of articles for healthcare parts when plastics and elastomers need to be combined in over-molding or insert-molding processes. Lastly, LSR self-bonding capabilities for two-component molding improve pump life with low hysteresis, strength after repeat sterilizations, and x-ray radio-opaque detection materials.
