Airfin ® "SILCOX" Silicone Membrane Diffuser

Product:  “SILICOX”-SILICON is silicon extruded/molded membrane product and  “SILICOX ” is proprietary material compounding code.
Characteristic:
Colour : white
Permanent Temperature Resistance: 140 C0

product1

Silicone material for plants which had potential problems with membrane failure such as fouling or chemical oxidation of rubber due to solvent exposure. silicone have a tendency over time to suffer from tearing due to flexure failure, which is something that does not significantly afflict EPDM membranes. Silicone is suited to cyclical operation, and does not  offers a cost benefit over  EPDM membranes.
