HERMETIC HOT MELT
COVERINGS
"SERIES CHM"

   Caratteristiche generali
 
The Hot Melt moulded coverings of the Series CHM are used to hermetically insulate and protect electrical and electronic components that must not come into contact with other components, metal parts or the external atmosphere. The CHM covering is made by moulding polyamide glue called Macromelt® at a low pressure, directly onto the component to be protected. By means of this technology, called Hot Melt, custom- made coverings can be produced.
