As an experienced manufacturer of moulded parts made of particle foam, we offer intelligent solutions for packaging, load carriers and technical parts up to a size of 2500 x 1200 x 600 mm or 1650 x 1550 x 600 mm moulded from one tool.
Our products are light-weight and elastic materials with shock-absorbing and insulating properties, whitch be given almost every imaginable shape. The high design freedom in combination with tailor-made product properties make it the ideal material.
Experience
since 1947
Since the production of body correction products under the Korrekta brand and the idea of developing an intelligent system that radically simplifies the installation of bathtubs, poresta systems has developed into a manufacturer of sophisticated parts made of particle foam.
The company's success is based on four main factors: committed employees, decades of experience, its own logistics centre and its own development department.
The numerous industrial property rights of poresta systems GmbH reflect the many innovations.
Quality and service are the top priorities at poresta systems. The approximately 160 employees, subsidiaries and representatives in Europe ensure that the requirements and wishes of our customers are granted.

Sustainability
Responsible use of our resources
Expanded polystyrene (EPS) consists of over 90% air by volume, the best prerequisite for sustainable material recycling.
At poresta, amongst other things, we recycle the rejects from the production of bathtub supports directly, so that they find a second life in new products. This is good for the environment, saves resources and helps to optimize production and finally reduce manufacturing costs.
The mechanical properties of EPS allow repeated usage over several years. When molded parts made of EPS reach the end of their life cycle, there are numerous established collection and recycling systems for them, because EPS is extremely easy to recycle.
