Round rubber cord are a good alternative in areas where the sealing is not too aggressive or under very high pressure. These cords can be installed very easily in inaccessible work areas and can be joint on site with adequate adhesive. They provide sufficient resistance and elasticity in the sealing applications.
NBR Nitrile Rubber Cord
NBR cord is compatible with hydraulic oils, water/glycol, oil in water emulsions, animal, minerals and vegetable oils, fuels and heavy oils. They have good mechanical properties, low compression set.
They are however not suitable for high temperature applications, protection against ozone, ketones, esters, aldehydes, chlorinated and nitro hydrocarbons
EPDM Rubber Extruded Cord
Good use in applications such as steam, hot water, air, UV, diluted acids and non-mineral oil base.
Can withstand temperature range from -50°C To + 150°C
EPDM Sponge Rubber Cord (Closed Cell)
Applicable in areas where rubber requires to withstand atmospheric conditions, ozone, sunlight UV ageing, moisture.
Used mainly as sealing applications.
Viton FKM Rubber Cords
This rubber cord offers excellent resistance to a wide variety of corrosive fluids at elevated temperature without major degradation.
Viton rubber cords have excellent resistance to ozone, oxygen, have good mechanical properties and low compression set.
Can be used in demanding work environments where temperatures can be between – 25°C To + 200°C
Silicone Rubber Cord
Silicone Cord is good in hot air up to 210°C. They have good insulating properties and tend to be physiologically neutral. They have excellent temperature resistance ranging from -55°C to + 200°C.
They however have low tensile strength, poor tear and wear resistance.
