EPDM Bellows

EPDM Bellows, also known as EPR Bellows and ethylene propylene Bellows, are designed as a cover or expansion bellows to take over axial, lateral and angular movements in pipeline systems and protect components against alkalis, strong alkaline, detergent, hot water, steam, ozone, etc.

EPDM Bellows | EPDM Rubber Bellows

EPDM Bellows & Rubber Bellows, also known as EPR Bellows and ethylene propylene Bellows, are designed as a cover or expansion bellows to take over axial, lateral and angular movements in pipeline systems and protect components against alkalis, strong alkaline, detergent, hot water, steam, ozone, etc.
EPDM Rubber Bellows and dust boots have wide sealing applications due to these excellent chemical resistance properties and its superior ozone resistance.
EPDM Bellows are usually produced by silicone rubber compression molding, extrusion moulding or rubber injection & transfer moulding. 
  

EPDM Bellows

EPDM Rubber Bellows Advantages:

  • Anti-ozone and weather resistance

  • Aging & Corrosion resistance

  • Waterproof and steam resistance: bathroom equipment, auto radiator && brake system.

  • Electrical insulation: wire & cable 
  • Good heat resistance (dry heat): Working Temperature range -50oC-150oC. (-60oF-300oF)
  • Low density and high filling property: can be made into low-cost rubber compounds bue to absorption of lots of oils and fillings.
 
EPDM Bellows Disadvantages:
1. Slow curing rate
2. Poor self-adhension and mutual viscosity 
3. Poor processability: difficult to blend with other unsaturated rubbers

4. Not recommanded for petroleum oils, mineral oil, die-ester lubricants or fuel exposure

Our Advantage for Rubber Bellows Production

  • Precision Own Mold-making Plant and Technology : Bellows Wall Thickness Tolerance can less: +/- 0.05mm and +/-0.1mm

  • In-depth knowledge of different elastomer rubber materials molded for rubber expansion joint & dust covers

  • Mature experience of flexible silicone rubber bellows quality controls:

a. Silicone Rubber bellows wall thickness sizes telorance: less +/- 0.05mm and +/-0.1

b. mini or less expansion joint flashing

c. mold maintenance in aim to up and down mold plate with horizontal stripe in exact position

d. good ejected molding to improve silicone bellows production efficiency

  • Rapid prototyping with full sizes production equipment and production materials.

  • In-depth knowledge of overmolded metal + silicone rubber bellows production
