ULTROXA®: Not only polymers

Beyond our product offer we provide you with key know-how to get the most out of the poly(2-oxazoline) platform.

We are experts in preparing tailor-made polymers to help you create innovative products in a wide range of areas. With ULTROXA®, you assure a scalable supply of high-quality materials, and the confidence of having the support of a world-leading team of experts committed to help you succeed.

We have adapted production methods to meet both the medical and the larger-scale non-medical industries, always providing the highest quality product for your application. ULTROXA® polymers have very narrow molar mass distributions (dispersities typically < 1.10), and high purity (> 95 %). In addition, we are also able to provide with cGMP grade materials.

We make the polymer you need…

… so you can focus on doing great science
