Which is better PVC or EPDM?
Composed of synthetic rubber, an ethylene propylene diene monomer (EPDM) roofing membrane offers superior weather resistance while remaining a cost-effective option. PVC, on the other hand, delivers exceptional seam strength; in fact, heat-welded PVC seams are stronger than the PVC roofing membrane itself.
What is better than EPDM?
Though more expensive, we recommend TPO roofing over EPDM roofing simply because it offers better rain protection and better performance. You'll get a longer lifespan from TPO, which helps to offset its higher cost. Plus, TPO is simpler to repair than EPDM.

Silicone is seen as the superior elastomer to EPDM due to the added benefits it provides, as well as generally providing longer life in service meaning less replacement costs and/or downtime.
Does EPDM deteriorate?
With the use of EPDM roofing adhesives, flashing problems occur where walls and roofs intersect. Over time, these adhesives degrade from prolonged exposure to harmful UV rays, because the heat that penetrates the thin membrane, causes premature separation from the flashing.

Disadvantages of EPDM rubber include: Poor resistance to petroleum oils and fuel. Poor resistance to mineral oils. Poor resistance to petroleum-based lubricants.
How is EPDM strength measured?
A: EPDM’s strength depends on the formulation, which depends on the application of the product. There are two major ways that strength is measured in most rubber formulas. One is tensile strength, or the amount of pressure it takes to stretch the rubber until it breaks.
What is an EDPM?
There are hundreds of thousands of different types of formulas that are simply referred to as “EDPM” despite slightly different makeups. The main qualification is that each one is based on an EPDM polymer that is then mixed with additives, cured or changed in some other way. Common ingredients added to EPDM polymers include carbon black or light fillers, antioxidants, processing aids, zinc oxide, petroleum-based plasticizers and curing materials.

What is EPDM compounded with?
As with most rubbers, EPDM is always used compounded with fillers such as carbon black and calcium carbonate, with plasticisers such as paraffinic oils, and has useful rubbery properties only when crosslinked. Crosslinking mostly takes place via vulcanisation with sulfur, but is also accomplished with peroxides (for better heat resistance) or with phenolic resins. High-energy radiation such as from electron beams is sometimes used for producing foams and wire and cable.
Why does EPDM rubber squeak?
EPDM seals can be a source of squeaking noise, due to movement of the seal against the opposing surface (and its attendant friction). The noise can be alleviated using specialty coatings that are applied at the time of manufacture of the seal. Such coatings can also improve the chemical resistance of EPDM rubber.

The molecular-level traits of EPDM products may be irrelevant to most people that are simply looking for a flexible material that will work well as a weather resistant rubber. That is perfectly fine since every piece of EPDM sheet rubber will have the same degree of functionality.
Is EPDM ozone resistant?
EPDM elastomer does have a few unsaturated groups in its molecular structure, which means it is not completely UV- and ozone-resistant, but the saturated backbone is sufficient enough to give the rubber such a high degree of weather resistance that it might as well be considered close to immune.
