Molded rubber bellows also called accordion rubber bellows,corrugatedpipe,rubber duct,are flexible seals that protect mechanical structures from the environment while permitting a range of motion. They are used inautoindustrial, transportation, and many other applications as a protective covering against dust, water, oil, grease, chemicals, and environmental elements such as mud, and snow. Rubber bellows can also reduce noise, resist shock and vibration, and withstand sunlight and ozone while remaining flexible at changing temperatures.
Fusteuses injection and compression molding to produce standard and custom rubber bellows in a range of materials, shapes, and sizes.

Molded rubber bellows are usually made ofNBR,NBR+PVC ,CR,silicone, or natural rubber. Each type of elastomer has different performance properties.
· EPDM rubber bellows have goodozone resistance and anti-age.
·NBRrubber bellows combine very good abrasion resistance with good tensile strength.
· Silicone rubber bellows lack abrasion resistance but haveexclent stretchresilience.
· Natural rubber bellows have good tensile strength and tear strength.
During material selection, it’s especially important to consider all of the environmental elements.For example,NBRprovideexcellent oil and solvent resistance but has poor flame resistance.EPDM provide high tensile and have excelent ozone and weather resistance . Siliconeresists a wide range of temperature but isn’t recommended for use with oils .
