QUADRANT EPP is a world leader in the production of structural plastics.

In our offer you will find both semi-finished products (plates, rods and sleeves) as well as finished plastic parts (machining, injection and casting).

We have over 70 years of experience in the processing of plastics. Quadrant in the field of engineering plastics has become synonymous with innovation. We have brought many key or even revolutionary changes since the invention of plastics. The pioneers of processing and technology like Polymer Corporation / Polypenco, Erta, Poly Hi Solidur, Cestidur and Symalit have been linked by us and work under the sign of the Quadrant group. In Poland, we were also pioneers when, as Kaprolan, we started our activity in 1989.

Quadrant was founded in 1996 as a bold idea to consolidate knowledge, experience and innovation in the field of engineering plastics. Less than 10 years later, thanks to the consequences and determination on the fast-growing niche market for engineering plastics, Quadrant has become a leading company in this segment, employing over 2,000 employees in 20 countries.

The year 2009 was the start of strategic cooperation with Mitsubishi Plastics, which allowed to strengthen the global position of the group, and in May 2013 Quadrant AG became a part of Mitsubishi Plastics.
