Rubber compounds for molding
Termogomma is specialized in the design and production of high quality rubber compounds, following the client’s specific requirements. Nbr,natural rubber,Epdm,Irr,Butil,Sbr,Fkm(Fpm9), Poliluteran(PU) and Silicon are only some of the regularly processed compounds.
The expertise, the possibility of a customized compound and the high flexibility ( fast delivery and minimum batches of about 35 kg) represent the added value of the company thanks to its internal mixers, it produces compounds for every sector, implementing mixed cuts between the elastomers and adding filler to increase specific characteristics.
For the compounds and the products created with them, it is possible to begin certification processes , for example MOCA 1935:2004 FDA for the food industry or KTW and ACS for drinking water.
What is a compound and how is it created?
The production of the compound represents the crucial stage in the production of rubber items.
The compound is realized through the combination of the elastomer (polymer of the rubber) with specific additives and chemical essences that allows characterization and conferment of physical and mechanical properties as well as a specific color.
The compound obtained from the mix of this recipe does not correspond to the rubber as we normally understand it. This compound has not the ability of vulcanizing, that means creating chemical bonds that make the material elastic.
The blending
The manufacturing of rubber goes through a double blending phase. The first (closed mixer), softens the elastomer and blends it to the other liquid and solid components. On the other hand, the second phase (opened mixers) flanks the compound making it more homogeneous and adding additional additives, such as accelerants, in order to prepare the material for the following vulcanization.
Sulfur and Peroxide are the mainly used mixtures for the acceleration, however the rubber technologists wisely measure the chemical mix depending on the sought result. .
In the lines of the opened and closed mixers, Termogomma produces continuously high quality compounds for its own rubber molding departments, and if necessary, for the direct use of some clients.
The wrought elastomers , depending on the polymers and charges used, obtain highly different physical and mechanical charcteristics, answering the needs of endless applications.
Once rubber is characterized and loaded, it is vulcanized in the injection and compression presses where the rubber compound is pressed and warmed and where the elastic bonds, which allow a better resistance to wear, traction forces and weather agents’ action, are created.
