Silicone is a common material for rubber bellow and dust boot applications in the medical, dairy, aerospace, food and beverage industries, due to its outstanding resistance to extreme temperatures and retention of compression and flexibility along with silicone's basic properties of being orderless, tasteless and noncorrosive. Additionally, silicone exhibits excellent resistance to ozone, oxygen, moisture and water swell which give the silicone bellows additional uses in the heating and air industries. Limiting factors of silicone rubber are low abrasion resistances and fuel resistances.
Our silicone BC-2273 rubber bellow is pre-engineered which means there are no set up or tooling cost, normally associated with rubber bellow applications. This makes the BC-2273 bellow a great "off the shelf" solution to finding obsolete replacement parts. Our customers also have found our pre-engineered bellows a cost effective solution for prototyping or applications requiring fast delivery such as the service or repair industries.
Bellows and rubber dust boots are versatile seals using in wide range of applications to seal dust and other environmental elements in applications with a stroke or designed range of motions.
