Our customers expect precise solutions to meet their exact design criteria. Property challenges like impact resistance, flame retardant properties, conductivity,  lubricated wear resistance, or highly transparent products with exceptional scratch resistance can be met.

Our technicians and engineers use their expertise to match any desired color or appearance to the final part. They adapt production processes to modify the properties of compounds i.e. using special fillers and fibers.

Sitraplas is an independent and privately owned company. We maintain our expertise by offering apprenticeships and further education with a special focus on training our junior staff.  We are involved in longterm research and development projects with
universities, and  participate in EU funded projects related to our field of interest.

In essence, we are continuously working on the improvement of our own products in order to be able to offer our customers exactly the “right mix”.


Our team of experts will support you at your facility beginning with the development of a prototype and up until the part starts series production. We not only assist you with adapting  the compound to your manufacturing process but can also make suggestions on improving process conditions on your machines.The product lead time during the initial development stage up to the first sample or order starting at 25 kg will be as short as possible.If you require toll compounding a short lead time is also possible. Any manufactured product will be available on short notice even several years after discontinued production.



SITRAPLAS serves many market segments. You can benefit from our experience in areas like automotive, electric and electronic industries, lighting fixtures, appliances, toys and many other special applications.
We also offer support in our pilot plant to companies who are not familiar with the compounding industry, to test formulations and find fresh applications for their newly developed raw materials.
