EPDM Rubber Sheet
EPDM Rubber SheeT KXT B400EPDM
EPDM has excellent weather resistant characteristics. Used as higher end applications on gasketing and seals for pumps. EPDM rubber, commercial grade, is similar to the EPDM rubber roofing, however the commercial grade is less rigid and formable than the roofing rubber. Commercial grade EPDM rubber is very resilient to alkaloids and detergents, it does have some mild resistant to petroleum. High pressure lines and pipe gaskets use EPDM rubber because of its resistance to ultraviolet light and temperature cycling. UV and temperature extremes cause most rubber material to become cracked brittle.
EPDM rubber material sheet is a great weather resistant material.
Advantages
• Completely UV stabilised making it highly resistant to ozone effects
and extreme weather conditions

• Very durable and long time usage
• Good low electrical conductivity
• Good Tensile Strength
• Excellent color stability
Application
• Harsh extremes as marine and underwater applications
• UV, ozone and general weathering applications
• High temperature water environments
• Pipe gasket seals and weather strips
• Outdoor and automotive applications
• Good for use with drinking water
