Our aeration discs are made using pressure-molded diaphragms. Milled with modern equipment and utilizing individual thermocouples and vacuum technology, we ensure repeatable high-quality products. Standard materials

Aeration Disc

For EPDM and Fluororubber coated EPDM. Molding ensures our film sheets have uniform density and balanced tear resistance. Other molding techniques, such as injection molding, produce products that look similar to ours, but those made by molding have multi-directional tear resistance, while injection molding products resemble wood with grain patterns, featuring单向 tear resistance.

Mastering the art of using plasticizers in EPDM film is crucial; excessive amounts or incorrect types can cause emulsified oils to draw out the plasticizers, leading to film shrinkage or increased hardness. Conversely, too little plasticizer can make the rubber lose elasticity, increase bubble size, and risk film bending failure. Extensive testing has been conducted on plasticizers and other SSI components of EPDM rubber, such as different types and quantities of additives, accumulating rich experience that is applied in practice. Punching holes and surface treatment of the film should also be considered. SSI uses specially shaped blades to punch holes into the disc-shaped film from the inside out, minimizing the size of the holes on the film surface.

By utilizing proprietary synthesis and surface treatment technologies, we are able to process smooth holes on hydrophilic surfaces. We inspect the uniformity of each membrane's hole depth to ensure even air release. It can quickly release small bubbles with a diameter of only 1-2mm. At all times, SSI strives to use environmentally friendly materials. Our aeration disks are mainly made of polypropylene, capable of withstanding temperatures up to 212°F (100°C) while maintaining stable performance.
