Creating strong bonds with LSR technology and Tritan
Medical devices and housings are getting a surge of chemical resistance and impact strength thanks to the integration of new liquid silicone rubber (LSR) technology with medical grades of Eastman Tritan™ copolyester. Momentive’s Silopren LSR 47×9 series provides strong in-mold adhesion with Tritan—without the need for primers.
Clear and opaque grades of Tritan have a lower Tg and require a lower processing temperature than other engineering polymers. Because Silopren LSR 47×9 can cure rapidly at relatively low temperatures, it’s possible to achieve optimal functional performance and efficient processing with Tritan.
This combination is ideal for applications that require properties like handling comfort, waterproofing, durability, and aging stability. Incorporating LSR technology enhances the advantages of Tritan, which include:

This combination is ideal for applications that require properties like handling comfort, waterproofing, durability, and aging stability. Incorporating LSR technology enhances the advantages of Tritan, which include:
- Outstanding chemical resistance
- Excellent impact strength and durability
- Made without bisphenol A (BPA) and halogens
- Superior noise-damping characteristics
- Excellent clarity and color retention after sterilization
- Color match (with certain opaque grades)
- Design flexibility
