SILPURANĀ® 6600/60 A/B

SILPURANĀ® 6600/60 A/B is a paste-like, easily pigmentable two-component compound with short curing times. Its vulcanizates are noted for their high transparency and excellent mechanical and electrical properties. Compared to the SILPURANĀ® 6000 series, the coefficient of friction of a post-cured article made of SILPURANĀ® 6600 is reduced by 50ā€“70%. SILPURANĀ® 6600/60 A/B is designed for medical applications in compliance with the Wacker Silicones Health Care Policy, including implantation for less than 30 days.

Application Details
  • The following studies were performed on vulcanizates of SILPURAN® 6600/60 A/B according to ISO 10993:
    • Cytotoxicity (ISO 10993-5)
    • Sensitation LLNA (ISO 10993-10)
    • Pyrogenicity (ISO 10993-11)
  • The following studies were performed on vulcanizates of SILPURAN® 6600/60 A/B according to USP class VI:
    • Acute systemic toxicity
    • Intracutaneous toxicity
    • Implantation test
  • No adverse effects have been detected at any of the studies performed.
  • Properly cured and post-cured vulcanizates of SILPURAN® 6600/60 A/B can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA 21 CFR §177.2600 "Rubber Articles Intended for Repeated Use" considering any given limitations on extractable and volatile substances.

Processing

The A and B components are delivered ready to use in 20 kg pail kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days.

Properties

SILPURAN® 6600/60 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.
