Highest quality compounds with constant repeatability

Commitment, to provide the highest quality compounds 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 end 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, then they get precisely weighted and checked again by computer for tolerance limits, all to eliminate human error and hence maintain highest quality and repeatability.We work in partnership with our customers, suppliers and staff, endlessly striving for improvements. Quality is our obsession.


Always offer full technical resources and development, regardless of industry sector.

We cooperate in partnership with our cleints, closely and confidentially, to develop compounds or solutions to any given problem. Whatever the industry, we can provide the silicone compound that meets given specific needs by varing the hardness, colour, elongation, rebound, media resistance, self-extinguisig properties, etc.
We are always looking forward, ready to accept new chalanges. We constantly discover new innovative uses of silicone based products and provide tailored solutions to implement them on the market.

We invite you to trust us your requirements.
