SILPURAN® 6610/40 A/B
- Chemical Family
- Silicones
SILPURAN® 6610/40 A/B is a paste-like, two-component compound. Its vulcanizates are noted for their significantly reduced tendency towards radical-induced reattachment, i.e., healing, of slit valve surfaces during sterilization by gamma irradiation and e-beam (≤ 75 kGy). SILPURAN® 6610/40 A/B is designed for medical applications in compliance with the Wacker Silicones Health Care Policy, including implantation for less than 30 days.

- Properties
SILPURAN® 6610/40 A/B meets selected test requirements of ISO 10993 and United States Pharmacopeia (USP) Class VI. It is designed for medical applications in compliance with the WACKER SILICONES HEALTH CARE POLICY including implantation for < 30 days and is particularly suitable for the economical production of large series of injection molded articles. At service temperatures above approx. 180°C the addition of heat stabilizers is recommended. Further information about an improvement of the heat stability by use of specific ELASTOSIL® Color Pastes FL can be obtained from the Technical Information Sheet "ELASTOSIL® Color Pastes FL" or the latest edition of our brochures.
