Our Mission

Our mission is to be the reference supplier of high-quality, high-purity, well-defined polyoxazolines. Much of the success of the current gold standard, polyethylene glycol (PEG), has been connected to its availability in the purity and definition required for its application in biomedicine. We strive to offer easy access of novel polymers to the research community, providing solutions unachievable with the current technology. We are committed to enable and support the development of poly(2-oxazoline)s applications in industry via design and production of tailor made products.

In all, AVROXA aspires to act as a catalyst in the development of new applications, boosting the poly(2-oxazoline) breakthrough in the market, with a special focus on biomedicine, where the PAOx/POZ technology enables solutions for unmet clinical needs with a strong societal impact.

Our Scientific Excellence

We offer high quality polymers to customers in the biopharmaceutical industry and beyond. Over 30 years of combined scientific excellence in the poly(2-oxazoline) field and our patent portfolio has enabled us to build a strong business case. AVROXA is a spin-off from Ghent University, Belgium.

Avroxa is founded a strong team of scientists including top organic and polymer chemists with a long trajectory in the general polyoxazoline field combined with application specialists.

Avroxa counts with Prof. Richard Hoogenboom as Scientific Advisor. Prof. Hoogenboom is a worldwide recognized expert in the field of poly(2-oxazoline)s and derivatives, and his research accumulates over 12,000 citations (full publication list available here).

Avroxa Research

AVROXA: 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, preparing tailor-made polymers for your application.

We are experts in preparing tailor-made polymers to help you create innovative products in a wide range of areas. We make sure that the polymer is optimized to the application you envision. With AVROXA, 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 developed proprietary 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 (dispersity typically < 1.10), and high purity (> 95 %).

Besides offering our know-how and the source of the highest quality PAOx/POZ in the market, we offer you our robust and versatile functionalization technology, combined with the highest defined polymers available. Our proprietary technology is already the basis of highly effective hemostats and a disruptive new medical device, general adhesive tissue tape by GATT Technologies N.V.

Feel welcome to explore our product range and to contact us for more information.
