EPDM has good low-temperature properties, with elastic properties to temperatures as low as −40 °C depending on the grade and the formulation. A roll of EPDM flashing with fleece on the back, used for waterproofing roofs. EPDM is stable towards fireproof hydraulic fluids, ketones, hot and cold water, and alkalis.
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in either closed-cell or open-cell form.
TPV can be used to make durable seals, gaskets, and grommets that are resistant to flex fatigue, harsh temperatures, and chemicals, as well as for a variety of sealing applications, including pipe seals, bridge expansion joints and curtain walls, parts for potable water, and pipe seals for sewer and drainage.
Butyl rubber sealant is used for damp proofing, rubber roof repair and for maintenance of roof membranes (especially around the edges). It is important [ citation needed ] to have the roof membrane fixed, as a lot of fixtures (e.g., air conditioner vents, plumbing, and other pipes) can considerably loosen it.
The most commonly used Cured Elastomer membranes are Ethylene Propylene Diene Monomer (commonly EPDM) and Neoprene, although all thermoset products combined fail to account for more than 10% of all commercial roofing. This is in part due to studies being released in the 1980s-early 2000's showing the average lifespan of thermoset membranes ...
