EPDM 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.

EPM/EPDM: Polymer of ethylene and propylene, generally divided into binary ethylene-propylene rubber and EPDM.It is characterized by excellent resistance to ozone, ULTRAVIOLET, weather and aging, ranking first in general rubber.Good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, low specific gravity, high filling fit.Heat resistant up to 150℃ , resistant to polar solvents such as ketones and esters, but not resistant to aliphatic and aromatic hydrocarbons, other physical and mechanical properties slightly inferior to natural rubber and better than styrene butadiene rubber.The disadvantage is that self - viscosity and mutual viscosity is very poor, not easy adhesion.Operating temperature range: about -50 ℃ ~+150 ℃.It is mainly used for lining of chemical equipment, covering of wire and cable, steam hose, heat-resistant transport belt, rubber products for automobile and other industrial products.

Flexible Expansion Joint & Bellows Main Manufacturing Process Quality Problems

We have the advantage of producing rubber bellows

1. Precision molding technology: the wall thickness tolerance of bellows can be less than +/ -0.05mm and +/-0.1mm.

2. Have an in-depth understanding of different elastomer rubber materials for rubber expansion joints and dust cover.

3. Rich experience in quality control of flexible silicone rubber bellows, with small wall thickness tolerance and small flash.

4. Good ejection molding, high production efficiency of silicone bellows.

5. Adopt full-size production equipment and production materials for rapid molding.
