Silpuran® & Elastosil® Silicone

Silpuran® & Elastosil® Silicone Rubbers

Foster is the an authorized distributor of Wacker silicone rubbers for medical applications in the United States. 

Silpuran® and Elastosil® offer a range of liquid silicone rubber (LSR) and high consistency rubber (HCR) products that provide excellent heat resistance as well as chemical and physical resistance without additional stabilizers. Both Silpuran® and Elastosil® offer a high level of transparency and colorability in addition to good resistance to UV radiation.

While both have history in the medical market, Silpuran® is unique in that all grades have met selected biocompatibility test requirements of ISO 10993 and United States Pharmacopoeia (USP) Class VI, as well as specifications in European Pharmacopoeia 3.1.9. Silpuran® grades are also supported by Device Master Files listed with the FDA. Silpuran® is intended for medical and pharmaceutical applications including those implantation for < 30 days.

When identifying grades within the Wacker portfolio, the first number represents the polymer series (6000, 6600, etc.), while the second number signifies durometer (shore A).
