Fine Bubble Diffusers

SSI manufactures fine bubble diffusers with compression molded membranes. Standard materials are EPDM and fluoroelastomer layered EPDM. Our disc diffusers include compression molding that ensures production of a part with even specific gravity and uniform tear resistance.

The tear resistance of a compression molded part is multidirectional, whereas the tear resistance of an injection molded part tends to be unidirectional just like wood which has a grain.
