	Roof Choices - EPDM
		EPDM is classified as a Thermoset material which means it is either fully-cured prior to being installed or that it cures during natural weathering after installation.
		EPDM has been in use on roofs in the USA since the 1960's and is one of the most common types of low-slope roofing materials.
		EPDM is a rubber material whose principal components consist of the compounds ethylene and propylene.

	EPDM rubber
		EPDM (ethylene propylene diene monomer) is a durable geomembrane with a 20-year proven performance history in exposed applications.
		EPDM rubber has been used for channel remediation by the USBR and has demonstrated effectively no change in properties after 9 years of service in both a covered and exposed application.
		Installation of the EPDM rubber liner was initially planned by Murrumbidgee Irrigation for August 2001 for the Lakeview Branch Canal, but did not proceed as the material could not be sourced before the recommencement of the channel operating season.

	SPRI - The recognized technical and statistical authority on the Single Ply Roofing Industry
		EPDM is an elastomeric polymer synthesized from ethylene, propylene and a small amount of diene monomer.
		In its typical form for roofing applications, EPDM sheeting is a cured, or vulcanized, material and is thus classified as a "thermoset." Simply defined, this means that the polymer's molecular structure is "set" as a result of heating during the manufacturing process.
		EPDM compounds have been shown to exhibit a high degree of stability under conditions of exposure to ultraviolet light, ozone, and extremes of both high and low temperatures.

	EPDM Synthetic Rubber for your roof and DIY roofing projects
		EPDM rubber will flex and resists all changes in temperature without cracking or peeling and is totally resistant to atmospheric pollution.
		EPDM synthetic rubber is not as new as you might imagine the first Synthetic Rubber Membranes, developed in America and were laid in the 1960's and are still protecting flat roofs some 40 years later.
		EPDM Synthetic Rubber Membrane is a remarkable material that can stretch, will not tear, split or crack and is unaffected by UV light and ozone.

	Contact adhesive and adhesive system for EPDM elastomers - Patent 4657958
		Adhesive compositions for bonding EPDM elastomers comprise (a) a neutralized sulfonated EPDM elastomeric terpolymer; (b) an organic hydrocarbon solvent; (c) an ionic plasticizer or mixture of ionic plasticiziers; (d) a phenolic hydrocarbon resin or mixture of phenolic hydrocarbon resins and (e) a material selected from mineral oils, petroleum oils, polybutenes, polyisobutylenes and ethylene/propylene copolymers.
		EPDM elastomers are of interest as roofing materials due to the fact that such elastomers provide significant advantages in flexibility and long term weathering resistance over conventional built up roofing (BUR) materials which are composed of tar paper composites which have poor flexibility and only very limited weathering resistance.
		The term "EPDM" as used throughout the specification and claims is used in the sense of its definition as found in ASTM-D-1418-64 and is intended to mean a terpolymer of ethylene, propylene and a diene monomer.

	Method for seaming wide panels of EPDM membrane to form a composite EPDM roofing membrane - Patent 6866732
		The longitudinal marginal edges of the cured EPDM membranes are positioned in an overlapping relationship as the cured EPDM membranes are fed in the first direction and then the overlapping longitudinal marginal edges are continuously seamed to form a composite sheet of indefinite length.
		The longitudinal marginal edges of the wide panels of cured EPDM membranes are positioned in an overlapping relationship as the wide panels of cured EPDM membranes are fed in the first direction and then the overlapping longitudinal marginal edges are continuously seamed to form a composite sheet of EPDM roofing membrane of indefinite length.
		As the overlapping edges of the cured EPDM membranes 14 pass between pinch rollers 40 and 40a, the opposing pinch rollers compress the overlapping edges thereby securing the membranes together to form a seam and enhancing the permanency of the seam.

	FiberTite Single-Ply Roofing Membranes vs EPDM Roofing Membranes (Site not responding. Last check: 2007-10-16)
		EPDM is a thermoset material that exhibits good weathering characteristics but can be problematic when creating field seams to ensure water-tightness.
		Sealing EPDM is comparable to patching an inner tube; the difference is that an inner tube patch is not expected to endure the heat, moisture and UV encountered in the roof environment.
		EPDM membranes generally forgo the expense of using "fiber" as an internal puncture barrier in favor of using mass or thickness to provide the illusion of durability.
