Diffuser Membrane Inner Slit Protection

SSI patent-pending fEPDM fine bubble diffusers are the first in the industry to offer significant inner slit protection from ageing and chemical attack. See below SEM report, thanks again to Mr. Kunihiko Sasajima, President of Nippon Plawder Co. Ltd, which identifies the presence of F within the inner slit, under 500x magnification.
PTFE membranes from SSI offer significant barrier layer protection on the top surface of the membrane.
fEPDM membranes provide barrier protection on the air side of the membrane, the water side, and within the inner slit. This means protection from fouling, chemical attack, ozone exposure, high temperature, etc… and there are far fewer places from which plasticizers within the EPDM substrate can leech.
