Technical Data
产品说明
Vamac® DHC is a dipolymer of ethylene and methylacrylate cured using peroxide vulcanization systems. This gum elastomer includes a small amount of processing aid, and has a nominal specific gravity of 1.04. It has a mild acrylic odor. Use adequate ventilation during storage, mixing, and processing to prevent accumulation of residual vapors. Storage stability is excellent.
Vamac® dipolymers are cured with peroxides and do not require a post cure cycle. Vamac® DHC was developed to improve the cure characteristics of the standard Vamac® dipolymer. Vamac® DHC provides for a higher state of cure and improved compression set. However, the heat age performance is impacted and slightly lower than the standard Vamac® dipolymer. Vamac® DHC is considered to be a 150°C continuous operating temperature elastomer. Vamac® DHC has better oil resistance with service lubricants exhibiting lower oil swell. Low-temperature flexibility is maintained.
Vamac® DHC would be of interest to those customers not needing the higher heat age performance of the standard Vamac® grades (165°C continuous) while wanting to maximize the properties from a non-post cure process with minimal cure time.
The properties of Vamac® DHC make it potentially suitable for a wide range of automotive applications, including powertrain seals and gaskets, rocker cover and bonded piston seals, oil coolant hoses, power steering hoses, crankcase ventilating tubes, coverings for fuel and coolant hoses, O-rings, grommets and spark plug boots.
Vamac® DHC is well suited for injection, transfer and compression molding, and is easily extruded.
