Carpinteria, California - June 15, 2004 - NuSil Technology, a leading formulator and manufacturer of silicone compounds for the healthcare, aerospace, electronics and photonics industries, announced today the launch of its pigmented masterbatches for liquid silicone rubbers. Targeted for companies serving healthcare markets, this product was designed for use with silicone elastomers meeting Class VI biological testing requirements and are available in two versions: unrestricted (may be considered for use in long term implantable applications) and restricted (may be considered for short term implantable applications, < 30 days, or for external applications).

“We realized that adding powder-based pigments such as titanium dioxide or barium sulfate to silicone systems can be a messy and inaccurate process,” said Brian Nash, VP of Marketing & Sales for NuSil Technology. “So NuSil’s solution is to add pigment to functional polymers, creating a user-friendly ‘solid/liquid’ mass that can be easily added to elastomer systems.”

The liquid silicone rubber pigmented masterbatches have a consistency similar to many liquid silicone rubbers. MED2-4800 (unrestricted) and MED2-4900 (restricted) contain 50% barium sulfate and MED3-4800 (unrestricted) and MED3-4900 (restricted) contain 50% titanium dioxide by weight. NuSil designed these products to be pumped by a third line into the dynamic mixing chamber in liquid injection molding equipment. This material can also be easily added by hand to other liquid silicone systems for compression molding (with a necessary de-airing step after mixing). For more information on these products, interested parties can contact technical sales at (805) 684-8780.

NuSil formulates standard and customized products based on silicone’s vast, unique array of properties. The company’s Quality System provides product quality by beginning with an effective design protocol and continuing up the supply chain from vendor qualification through re-inspection of finished product inventories.
