Abstract

The invention relates to an element for a housing for electrical apparatus, comprising a composite composition comprising a polymer matrix comprising at least one polyamide polymer, having dispersed therein: glass fibres, titanium dioxide and a compound in the form of magnesium dihydroxide Mg(OH)[2] particles coated with a layer comprising a vinylsilane compound.

Description

technical field [0001] The present invention relates to housing elements for electrical equipment comprising a flame retardant composite composition comprising a novel combination of at least one polymer belonging to the category of polyamides, at least two specific types filler and at least one specific flame retardant, the composition corresponds to very favorable mechanical properties combined with excellent flame retardancy and more particularly exhibits: [0002] - low water absorption; [0003] - High arc tracking resistance; [0004] - High flame resistance; [0005] - is not corrosive to the appliance with which the composition comes into contact during its shaping; and [0006] - not harmful to the environment and human health intended to come into contact with the constituent composition of the housing element. Background technique [0007] Composite compositions based on at least one thermoplastic polymer, such as polyamide-based compositions, are commonly use...
