The Most Extreme Environments. The Purest Solutions.

The NuSil™ brand, the global leader in Medical Grade silicones, brings over 40 years of success in developing products for the most extreme environments, from deep inside the human body to the harsh conditions of outer space.

Supported by our high-touch approach to customer care, our best-in-class product lines are the choice across the drug delivery, medical implants, general healthcare and skin care industries.

Let us show you how we're transforming the science of silicone into the Chemistry of Care™.

The extreme conditions inside the human body are as demanding as those of outer space. To create success in these environments, we look beyond standard methods.

We’ve incorporated controls to remove impurities at every step in the manufacturing process. We carefully select our raw materials and custom make equipment that produces the most refined intermediates and the purest finished products.

And we complete this with our Proprietary Purification Technology, purpose-built to produce silicones with the lowest volatility levels.

The result is our Medical Grade Ecosystem, which creates the purest silicones in the industry.
