Rostabil TNF is a specialist additive for plastics used as a process stabilizer. It prevents degradation of polymer materials during processing, strengthens the colour stability of materials containing pigments and provides transparency to non-pigmented products. The Rostabil TNF stabilizer is in the form of a homogeneous liquid, which makes it possible for it to be used it already at the stage of synthesis of macromolecular compounds. In addition, high hydrolytic stability enables the use of the stabilizer in processes occurring in a strongly alkaline environment.
During processing, plastics may decompose, and therefore thermal stabilizers are used to prevent further degradation already at the processing stage. In the context of polymeric materials, the term degradation (aging) is used to determine changes in physical properties caused by chemical reactions. As a result of these reactions, the polymer chain ruptures, which causes a decrease in the molar mass of the macromolecular compound. These changes directly affect the course of the processing process and the functional properties of finished products, i.e. colour, gloss, shade.
In order to prevent the destructive effects of oxygen, temperature or ozone, stabilizers or mixtures thereof are used that exhibit synergistic synergistic effects. Rostabil TNF can be used as a co-stabilizer with primary stabilizers (zinc, barium, calcium stearates) during PVC processing. It is widely used in the production of powder paints. Rostabil TNF is one of the most commonly used antioxidants in the production of synthetic rubbers. Due to its unique non-staining properties, it is widely used in SBR processing, in particular in synergy with phenolic stabilizers.
