Our company profile

The PolymerTechnik Ortrand GmbH (PTO) is a medium-sized enterprise (SME), whose roots date back to 1927. The main focus of our business is in the development and production of elastomer-coated fabrics and elastomer sheets without fabric lining.

Our competitive edge is particularly due to the fact that we can apply all the elastomers available on the market (including silicone rubber) to a wide variety of fabrics as well as knitted and crocheted materials. For this purpose, we make use of diverse coating and vulcanisation possibilities.


With our state-of-the-art machine park, we are not only able to vulcanise the coated fabric, but also design distinct textures according to customer requirements. In addition, we also offer a variety of different colour variations. We possess the necessary expertise and know-how and – together with our customers and partners – develop customised products that meet the highest standards. Our products are used in all branches of industry. We continually invest in progress while paying attention to an optimal combination of corporate values and company development. As a matter of principle, we act reliably on a customer-specific basis and set standards with our quality requirements.

Unsere Unternehmensgeschichte



The entrepreneur Gustav Schwarzwald founded the rubber factory in Ortrand. Here sanitary rubber products were produced until 1945.



A total of 400 employees produced rubberised fabrics, rubber sheeting and clothing. Furthermore, two new production plants and an administration building were built and investment took place in modern impregnation, calendering and vulcanisation lines.


Political transformation

Following the reunification of Germany, the new »Gummiwerk Ortrand GmbH« company was initially launched. Notwithstanding this, however, it ceased production in 1995.


New company

Three shareholders – Peter Schulz, Albrecht Clemens and Gernot Lange – established the new company »PolymerTechnik Ortrand GmbH« in 1996. Production was restarted with 6 employees, with the focus on the manufacture of rubberised fabrics, rubber sheeting and convertible tops.



The HÜBNER GmbH & Co. KG company, based in Kassel, acquires shares of the previous PTO shareholders. The operating business is managed by Peter Schulz and Harald Ossendorff is appointed as a further Managing Director of HÜBNER GmbH & Co. KG.


Change in Managing Director

In 2010, Kirsten Schmaler succeeds Peter Schulz. 2012 witnessed the biggest volume of investment in the history of PTO to date.


PTO awarded the Zukunftspreis Brandenburg

This Zukunftspreis, honouring companies for creative investing in the future, has been advertised and awarded since 2014 by the various Chambers of Commerce in Brandenburg acting in concert. .

2016 -2018

20th anniversary of the company

In 2016, PTO celebrates its 20th anniversary with its partners and employees. At the beginning of 2018, Ingolf Cedra succeeds Harald Ossendorff as Managing Director of HÜBNER GmbH & Co. KG.
