What are the properties of EPDM?
EPDM elastomers have excellent heat, ozone/weathering, and aging resistance. They also exhibit excellent electrical insulation, compression set, and low temperature properties, but only fair physical strength properties. Their resistance to chemicals is generally good.
What is the composition of EPDM?
EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers (3% – 9%) which provide cross-linking sites for vulcanization (rubber hardening).
What is EPDM rubber used for?
EPDM rubber is a type of synthetic rubber. It is extremely durable and flexible and therefore has a wide range of applications, including in vehicles (where it is used for window and door seals, as well as cooling system hoses), cold-rooms, non-slip coatings for decks and playgrounds and many others besides.
Is EPDM thermoplastic or thermoset?
EPDM rubber belongs to the thermoset elastomers (rubber) classification, while thermoplastic PI belongs to the thermoplastics. There are 8 material properties with values for both materials.
Is EPDM an insulator?
EPDM exhibits outstanding resistance to heat, ozone, steam, and weather. It is an electrical insulator.
Is EPDM conductive?
EPDM Properties With similar properties to silicone rubber below 250 degrees F, EPDM is resilient, has low electrical conductivity, and adheres easily to metals. Additionally, unlike silicone, it’s not flame resistant, and it’s also not recommended for food application.
Is EPDM UV stable?
EPDM and Silicone have excellent resistance to environmental conditions. Both rubbers can withstand general weathering, Ozone and UV making them ideal for outdoor applications.
Is EPDM water resistant?
Of all the rubbers, EPDM is the most water resistant, which is why it’s so popular for outdoor applications and is often used as a roofing material. EPDM also offers good electrical resistance. Its chemical properties make it especially suitable for electrical insulation and gaskets.
Does EPDM melt?
The thermal behavior of an EPDM rubber mixture was measured between –125°C and 160°C at 10 K/min. The melting above the glass transition (peak temperature at 31.4°C) is typical for the behavior of a sequence-type EPDM.
Is EPDM elastomeric?
EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers having a saturated chain of the polyethylene type (the M deriving from the more correct term polymethylene). EPDM is made from ethylene, propylene, and a diene comonomer that enables crosslinking via sulfur vulcanization.
Is EPDM flammable?
However, EPDM is a flammable material with a very low limiting oxygen index (LOI) value, which greatly limits its further development and application [1].
What temperature is EPDM?
EPDM – excellent heat and steam resistance for o-rings Ethylene propylene rubber has a temperature range of -50°C to +120°/150°C (-60°F to +250°/300°F), depending on the curing system.
What does EPDM mean?
EPDM stands for Ethylene Propylene Diene Monomer, a synthetic rubber used in a range of applications.
What does EPDM roofing stand for?
Invented in the 1970s, EPDM roofing is a highly durable rubber roofing membrane with effective applications for commercial roofing with a low slope. The acronym EPDM stands for Ethylene Propylene DieneTerpolymer, a name that reflects its chemical origins, being the derivative of natural gas and oil.
What is EPDM sheet gasket material?
EPDM Gasket Materials. EPDM Gaskets made using this material are highly resistive against water, ozone as well as oxygen which makes it useful to be applied in open condition sealing. They can be used in different weather conditions and are commonly used in low pressure pipe seals. Ethylene Propylene Diene Monomer (EPDM): EPDM is a black plate finish sheet with superior resistance to weathering, ozone and UV exposure.
Is EPDM UV resistant?
EPDM (Ethylene Propylene Diene Monomer) all-weather bands are UV and ozone resistant and are not affected by changes in temperature. These attributes make EPDM the perfect banding/bundling material for all-weather outdoor use.
