Spoiler rubber dam, also known as disturbed flow rubber dam, adds the spoiler seismic structure at the base of common rubber dam. It is made of rubber cloth vulcanized by EPDM and synthetic fabrics. Rubber dam can be inflated by air or water. It can effectively prevent rubber dam oscillating or squirming, thereby reduce the friction with downstream rubber protective layer result from rubber dam vibration. It is usually used to retain water, control flood, agricultural irrigation, power generation, beautify environment, etc.

Spoiler rubber dam consists of rubber bladder, anchoring clamping system, air evacuation system, anti vibration and anti vibration spoiler, abrasion resistant protective layer. Following I will introduce the five parts in detail.
Rubber bladder
Spoiler rubber dam is made of 90% EPDM. EPDM is a kind of special rubber with notable features in extreme temperatures, also can be resistant to weathering, ozone, UV. Spoiler rubber dam uses high strength polyester fab
