Our values

expert advising

We dedicate ourselves to provide our customers a rapid and expert advice at all times (rapid advice and expertise) by choosing an appropriate compound or solution, which enables our customers the journey from idea to realization with ease.

Our main focus has always been to produce compounds of the highest quality with superior processability at competitive prices.

Highest quality compounds with constant repeatability

Commitment to provide compounds of the highest quality with constant repeatability. In the laboratory, in addition to the development of new compounds, we regularly carry out checks of newly arrived raw materials and perform control checks of all outgoing compounds. On this basis we issue a test report, which is enclosed to every single compound dispatched. This way the final customer can verify the quality of the material received.

We keep track records of every single compound produced, experimental or commercial. All ingredients are checked using bar code and have to match the code on the work order; after that they get precisely weighted and checked again by computer for tolerance limits, All this is done to eliminate human error and hence maintain the highest quality and repeatability. We work in partnership with our customers, suppliers and staff, endlessly striving for improvements. Quality is our obsession.


best compromise between price and performance

As a rubber compounder we try to achieve the best compromise between the price and the performance of compounds by choosing the right elastomer or blend of polymers to which various additives and fillers are added in order to fulfil the requirements or to satisfy customers' request.

We are certified according to ISO 9001 standard already since 2009, as well as according to ISO 14001 since 2018. We have received a Platinum AAA Credit Rating by Bisonde.
