Neoprene Bellows | Custom Rubber Bellows | Dust Boots

Neoprene Bellows

Neoprene bellows, also known as Chloroprene Bellows, CR Bellows, or Expansion Joints, Convoluted Rubber Bellows, or Rubber Dust Boots, are usually used as sealing elements, and dust covers & dust boots in automotive industry, refrigeration industry and others.

Neoprene Bellows have better comprehensive performance than other rubbers.

Neoprene Expansion Joint Bellow is usually manufactured by compression mould, extrusion mould and rubber injection mould.

Custom Molded Rubber Bellows Manufacturing Process  

Neoprene Bellow Functions: 

• Machinery seal;

• Dustproof;

• Absorption of vibration;

• Noise Reduction;

• Electrical insulation.

Neoprene Bellow Advantages:

• Wide Working Temperature Range: -40℉ / -40℃—248℉ / 120℃

• Excellent Elongation: Up to 600%

• Good Tensile Strength

• Good Aging Resistance

• Oil & Grease Resistance

• Chemical Resistance: Acid and alkali can hardly destroy the neoprene material.

• Weather Resistance: Excellent performance in anti-ozone and anti-weather.

• Better flame resistance: Neoprene is the best flame-resistance material among general rubbers. Neoprene cannot combust spontaneously. It burns when contacting flame, but puts out by itself once isolating the flame.

Neoprene Bellow Disadvantages:

• Poor cold resistance

• Raw rubber has poor stock stability.
