Rubber Sheet for Valves (Latex-free Rubber membrane)
A valve is made by a rubber membrane that opens up when the person exhales and closes when exhalation ends. This piece of rubber valve makes exhalation easier and helps to reduce temperature inside the mask, minimizing condensation and moisture build-up.
Min Yuen Rubber produces latex-free rubber sheet for mask suppliers to die cut into disk valves for respiration purpose. We offer different packaging roll sizes and colors as specified.
