Room Temperature Vulcanizing (RTV-2)
Medical Grade RTV Silicone
Medical Grade RTV Silicone
Room Temperatures Vulcanizing (RTVs) are 2-part systems which can be easily mixed and cured into soft and durable elastomers. Silicone RTVs have long been used in the manufacturing of soft parts in contact with the patient because of their inherent comfort and biocompatibility.
Our Silbione™ RTVs allow designers and manufacturers to :
- Create end products with a life-like feel
- Optimize comfort for the end user thanks to a wide range of hardness (starting from Shore A 1)
- Improve the durability of the final piece with exceptional mechanical properties
- Increase their productivity with easy to mix and degas low viscosity silicone RTVs
Example of applications include :
- Prosthetic liners
- Shoe insoles
- Pellots, bandages & orthotics inserts
- Medical training aids
- High-end adult novelties
Elkem Silicones offers the following ranges for Room Temperature Vulcanizing (RTV) silicones under the Silbione™ brand:
