Vamac is a type of ethylene acrylic elastomer (AEM) material that offers a unique combination of properties, including excellent heat resistance, chemical resistance, and low-temperature flexibility. These properties make Vamac ideal for use in a wide range of automotive, industrial, and oil and gas applications.

Vamac is a synthetic rubber material that is made by copolymerizing ethylene with acrylic acid or methacrylic acid. The resulting polymer has a unique combination of properties that make it highly resistant to heat, chemicals, and abrasion. Vamac is also highly flexible at low temperatures, making it ideal for use in cold weather applications.

One of the key advantages of Vamac is its excellent heat resistance. Vamac can withstand temperatures up to 175°C (347°F) without losing its shape or breaking down. This makes it ideal for use in high-temperature applications such as engine seals, gaskets, and hoses.

Vamac also has excellent chemical resistance, making it ideal for use in applications where exposure to harsh chemicals is common. Vamac can resist exposure to a wide range of chemicals, including acids, bases, solvents, and oils. This makes it ideal for use in automotive and industrial applications such as fuel systems, transmission seals, and pump components.

Another important property of Vamac is its low-temperature flexibility. Vamac remains flexible at temperatures as low as -40°C (-40°F), making it ideal for use in cold weather applications. Vamac is often used in applications such as air intake hoses, fuel system components, and engine seals in cold weather regions.

Vamac is available in a range of grades, each with different properties tailored to specific applications. For example, some Vamac grades may have improved heat resistance, while others may have improved chemical resistance or low-temperature flexibility. Some grades may also be optimized for specific processing methods, such as injection molding or extrusion.

One of the most popular Vamac grades is Vamac G, which is a general-purpose grade used in a wide range of automotive and industrial applications. Vamac G is known for its excellent heat resistance, chemical resistance, and low-temperature flexibility, making it ideal for use in applications such as engine seals, gaskets, and hoses.

Another popular Vamac grade is Vamac AEM, which is a high-performance grade used in applications such as turbocharger hoses, air intake hoses, and fuel system components. Vamac AEM has improved heat resistance and chemical resistance compared to Vamac G, making it suitable for use in more demanding applications.

In addition to its properties, Vamac is also easy to process and can be molded into a wide range of shapes and sizes. Vamac can be processed using a variety of methods, including injection molding, extrusion, and compression molding.
