Rubber cords are in demand for exacting commercial and industrial applications. No longer are rubber cords used only in applications where flexibility is needed. Types of rubber used in making cords
- Nitrile Rubber (NBR)
- Ethylene Propylene Diene Monomer (EPM, EPDM)
- Silicone Rubber
Different rubber materials used to make rubber cords have different properties. Some common properties of rubber cords are as follows:
- Available in various Hardness (Durometer, Shore A: 20 to 80).
- Various colors are available. Natural or any color (translucent or opaque).
- Should avoid prolonged exposure.
- Low compression set requirements.
- Good resistance to oil.
- Good chemical resistance and resistance to alcohols and benzene.
- However not suitable for contact with acetone.
- Good ozone and weather resistant properties.
- Electrically conductive material.
- Low temperature grade suitable for use at -40 degree.
- High temperature sealing applications.
- Can be joined to o-rings.
- Food and medical equipment, machinery, transportation.
