The chemical and galvanic industry<\/strong> represents one of the most complex contexts for polymeric materials, due to the combination of high temperatures, highly corrosive environments and intense electrical currents<\/strong>. The experience of Progalvano<\/strong>, an Italian company leader in the production of rotary barrels for galvanic treatments<\/strong>, demonstrates how high-performance compounds<\/strong> can successfully replace traditional materials, such as PVDF<\/strong>, maintaining reliability and durability over time.<\/p>\n In galvanic processes<\/strong>, the barrels mounted on rotors must resist not only the aggression of acidic and alkaline solutions<\/strong>, but also the presence of free ionic species<\/strong> and strong electrical currents. The main challenge concerned the realization of the closing springs<\/strong> of the barrels:<\/p>\n The solution was identified in LATENE AG3H K\/10<\/strong>, a heat-resistant and mechanically reinforced compound<\/strong> based on polypropylene (PP)<\/strong> loaded with carbon fiber<\/strong>.<\/p>\n Main technical characteristics:<\/strong><\/p>\n The field tests<\/strong> confirmed that the new springs produced in LATENE AG3H K\/10<\/strong> fully meet the design specifications<\/strong>, offering:<\/p>\n Although the Progalvano case concerns chemical-mechanical resistance, the formulation technologies of advanced compounds<\/strong>, such as those based on carbon fiber or graphite<\/strong>, are the same used also for thermally conductive compounds for LED<\/strong> and electronic devices.<\/p>\n Both applications share similar objectives:<\/p>\n
\nIn these scenarios, the choice of material must guarantee mechanical resistance, thermal stability and chemical inertness<\/strong> even under extreme operating conditions.<\/p>\nFrom Galvanics to Advanced Compounds: the Progalvano Project<\/h2>\n
\nTraditionally, Progalvano used polyolefins and fluorinated resins for the construction of its components, but new strongly alkaline-based<\/strong> processes required a more performant material<\/strong>.<\/p>\n\n
