MuCell Technology

Dupont Automotivel is a microcellular technology for encapsulating electrical and electronic components. Operating parameters are typical: at least 20% faster cycle time, 20°F lower melt temperature, 50% lower injection pressure and 75% lower clamp pressure than with solid materials.

The technology provides economical, damage-free encapsulation of coil-wound devices, sensors, integrated circuits and other delicate electrical and electronic assemblies. The process also makes it easier to mold parts to close dimensional tolerances.

In the MuCell process, a supercritical fluid, typically nitrogen or carbon dioxide, is introduced into the polymer melt in the molding machine barrel. When the polymer is injected into the mold, pressure drops, causing the formation of microcells. The dissolved fluid also acts as a temporary plasticizer that lowers polymer viscosity.
