Vamac®

A copolymer of ethylene and methyl acrylate, with a small amount of third monomer added to provide cure active group in the polymer chain, vamac® exhibits properties similar to those of polyacrylate, but with an extended low temperature limit and better mechanicals.

Key Use:

seals foe automotive applications, such as automatic transmission & power steering systems.

Working Temperature Range: -40 °F to + 300°F. (Dry Heat Only.)

Features:

• Ideal for automotive sealing uses, Vamac® features excellent heat resistance, outstanding resistance to ozone and sunlight aging, moderate resistance to swelling in oils, and very low permeability to gases.
• With a maximum reinforced tensile strength of 2,500 psi, Vamac® mechanical properties of adhesion to metal, tear resistance, flex life, abrasion resistance and compression set resistance are all rated as "good".
• Resistance to water, engine coolant mixture (glycols), dilutes acids and alkaline is also good.

Note: Vamac® is a Registered Trade Mark of DuPont Dow Elastomers
