UAB “Prustitas” has a wide network of partners since 2002. We work with reliable and trustworthy suppliers.


For over 30 years, CROMA® has been studying, developing and manufacturing computer-controlled hot wire cutting systems. These machines make it possible to cut practically all the Thermo-fusible foams, but also plastic materials of small thickness. Over the years, we have built the internal components of these systems. Our philosophy is to supply not only machines, but also complete means corresponding to the needs of our customers, either by a very wide range, by special machines on specifications or by our experience.

Polychem Systems

Pioneers in the polyurethane industry

The polyurethane sector has seen some difficult times on the Polish market. The experience gained over the nearly 35 years of our activities, during periods when the political landscape was transformed and economic trends changed, has taught us how to build our business future. When the polyurethane sector was at its larval stage, Polychem Systems Sp. z o.o. was developing the production technologies which would become the foundation of our success in the years to come.

Knauf Industries

Our offices and factories are in more than 80 countries.

We have gained global recognition for high quality products in the construction industry, which has given us the foundation to start out in the plastics industry as a Knauf Industries company.
We supply foam products including foam polystyrene (EPS), polypropylene foam (EPP) and thermoplastic injection molded components.

Knauf Industries is a company that has been operating in the market for more than thirty years. This period allowed us to gain experience in the production of plastics and gain the trust of customers.

The highest quality of our products and our idea of providing added value in the form of ready-made services that facilitate logistics, design and production processes have also gained the support of customers in the Polish market.
