Polymer Systems Technology presents the debut of the NuSil Technology Colour Masterbatches for Healthcare Silicones.

The MED-4502 and MED-4900 series consist of pigments dispersed in a vinyldimethylterminated, polydimethylsiloxane polymer and are offered in a range of colours, including black, red, orange, yellow, green and blue. Custom colours, obtained through the blending of eight base colours, are available upon request.

These masterbatches eliminate the use of powders that may contaminate clean room environments and reduce production time. In addition, their strict quality controls ensure colour consistency. “NuSil sees the advantage of these masterbatches as two-fold, as incorporating pigments into elastomers in accurate amounts and without the mess is beneficial to fabricators serving the medical device community,” said Derek Williams-Wynn, Director of PST. “The device manufacturer can benefit by enhancing the aesthetics of their devices and/or improving the identification of size-specific devices” MED-4502 offers simple, accurate pigmentation of high-consistency silicone materials, which may be molded, calendared or extruded, while MED-4900 allows easy and precise pigmentation of LSRs and low-consistency materials, which may be injection moulded.

Both product lines are supported by master access files with the U.S. FDA; USP Class VI biological testing, including systemic toxicity, intracutaneous, seven-day muscle implantation; and hemolysis and 90-day muscle implantation with histopathology studies.

NuSil’s MED-4502 colour masterbatches are available in 50-gram and 454 gm, and 11.35 kg packaging, MED-4900 are available in 50-gram and one-, 3.63 kg- and 18.2 kg packaging.
