High temperature and ozone nemesis: How does EPDM rubber withstand environmental challenges?
EPDM rubber (ethylene propylene diene monomer rubber) is a synthetic rubber that is widely used in a variety of industries. This M-grade rubber is classified according to ASTM standard D-1418 and is a high-performance material with a chemical structure of saturated polyethylene chains. EPDM is a combination of ethylene, propylene and a diene copolymer that supports vulcanization cross-linking to achieve the required elasticity and durability.
The true potential of EPDM rubber lies in its chemical composition and manufacturing process, which enable it to perform exceptionally well in extreme conditions.
Characteristics and advantages of EPDM
The properties of EPDM rubber make it excel in many applications. Specifically, this rubber performs better in terms of heat resistance, light resistance and ozone resistance than traditional unsaturated rubbers such as natural rubber, SBR and chloroprene rubber. This property makes EPDM have excellent durability in harsh external environments.
EPDM has a heat resistance of up to 150°C, making it ideal for applications that require prolonged exposure to high temperatures.
Wide Application of EPDM
EPDM is widely used in the automotive industry, including door seals, window seals, etc. In addition to these, EPDM is also used to make many waterproof materials and sealing materials, such as seals for refrigerator doors and components of industrial respiratory protection masks. These applications require materials that are not only elastic but also impermeable to liquids.
In addition, EPDM's low temperature resistance also makes it not succumb to the -40°C environment. This is a very important feature for equipment that needs to operate in extreme climates.
EPDM demonstrates its superior performance both as an electrical insulation material and as a stabilizing material for fire-resistant hydraulic oils.
EPDM maintenance and ductility
The durability of EPDM is particularly important in terms of maintenance costs. Due to its long-term stability, EPDM's service life can reach decades, which can bring considerable economic benefits to companies that want to save maintenance resources. However, certain characteristics of EPDM, such as chemical interactions with bituminous materials, still require attention to avoid potential corrosion issues.
Environmental potential
With environmental protection gaining increasing attention today, EPDM's low maintenance cost and sustainability make it an ideal choice. Especially in the construction industry, the use of EPDM roofing materials not only provides excellent waterproof performance, but also ensures that rainwater is not polluted, which is especially important for rainwater collection systems.
Using EPDM as the material for safety ground also effectively reduces the risk of accidental injuries in playgrounds.
Future Outlook
The output of synthetic rubber exceeded 10 million tons per year in the 2010s, and even reached more than 15 million tons per year in 2017 and 2019. With the continuous advancement of technology and the market demand for more durable and environmentally friendly materials, EPDM rubber still has huge growth potential in the future.
The comprehensive properties of EPDM rubber make it an ideal choice for many applications, whether in the industrial, construction or automotive sectors, where it continues to face environmental challenges. So, in future applications, how should we further improve the performance of EPDM to cope with ever-changing environmental demands?
