Abstract

Electrical component comprises a casing of synthetic material which encapsulates the component hermetically with respect to the atmos. The synthetic material contains a filler, pref. up to 60% comprising a material which absorbs or adsorbs noxious reagents penetrating within the casing. The casing is pref. surrounded by a sealing agent e.g. epoxy resin. The synthetic material is conventional e.g. thermoplastic or thermosetting plastic material, to which the absorbent material e.g. active C or a molecular sieve (zeolite) is added in powdered or granulated form, by a conventional method. After shaping by injection or pressing, the synthetic material is heated to degasify the synthetic fraction of the moulded article and activate the absorbent material embedded in it.
