Mimoyin ePTFE waterproof breathable membrane adopts high-strength expanded polytetrafluoroethylene base material, designed for fully sealed electronic housings that need pressure balance and long-term dust & waterproof protection.
The micro-pores of ePTFE block liquid water, dust, oil mist and contaminants completely, while allowing air molecules to circulate freely. It quickly balances internal and external pressure difference, eliminates condensation and prevents housing bulging or suction deformation caused by temperature changes.
