EPDM rubber Potential Application in building
EPDM rubber is used in vibrators and seals; glass-run channel; radiator, garden and appliance hose; tubing; washers; belts; electrical insulation, and speaker cone surrounds.
Ethylene Propylene Diene Monomer is a synthetic rubber most commonly used in single-ply roofing because it is readily available and relatively simple to apply. EPDM Waterproofing Membrane has properties of light, long life,ageing resistance, high extensibility and draftability .
EPDM exhibits satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, and alkalis, and unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents, and concentrated acids.
It is also used as a medium for water resistance in electrical cable-jointing, roofing membranes, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, and many other applications. EPDM Waterproof Sheet has cold construction operation, no environment pollution and simple operation.
The new generation of EPDM, with a FleeceBack, has been combined with a polyester fleece backing and fabricated with a patented hot melt adhesive technology which provides consistent bond strength between the fleece backing and the membrane.
The main properties of EPDM are its outstanding heat, ozone and weather resistance. The resistance to polar substances and steam are also good. It has excellent electrical insulating properties.
It is a low cost membrane, but when properly applied in appropriate places, its current warranted life-span has reached 30 years and its expected life-span has reached 50 years and this continues to rise with every year that passes.
Typical properties of EPDM vulcanisates are given below. EPDM can be compounded to meet specific properties to a limit depending first on the EPDM polymers available, then the processing and curing method(s) employed.
