Liquid silicone rubber technology enhances Eastman Tritan™ copolyesters.

There’s a growing demand in today’s medical market for innovative medical devices and housings that provide a superior combination of chemical resistance and impact strength. Thanks to advancements in liquid silicone rubber (LSR) technology, manufacturers are now able to meet this demand using medical grades of Eastman Tritancopolyester. 
Momentive's Silopren LSR 47×9 series provides strong in-mold adhesion with Tritan™ without the need for primers. This combination is ideal for applications that require properties like handling comfort, waterproofing, durability, and aging stability, including:
  • Respiratory devices
  • Sealing elements
  • Gaskets for joints in housings and hardware
  • Buttons and switches on electronic housings and hardware
  • Vibration reduction
  • Membranes and lenses for electronic device housings
Clear and opaque grades of Tritan™ have a lower Tg and require a lower processing temperature than other engineering polymers. The ability of Silopren LSR 47×9 to cure rapidly at relatively low temperatures is optimal for achieving functional performance and efficient processing with Tritan™. Incorporating LSR technology enhances the advantages of Tritan™, which include outstanding chemical resistance, excellent impact strength and durability, clarity and color retention, and design flexibility.
This single-step, integrated molding process can shorten cycle times and reduce input costs. Contact us to learn more about optimizing overmolding with Tritan™ medical grades.
