| 摘要 |
<p>The present invention relates to a material, especially for the insulation of an electrical cable, based on a polysiloxane polymer of the VMQ type, this polymer being vulcanisable, without reheating, with the aid of organic peroxides and having a Shore A hardness at least equal to 40. The mixture furthermore includes: - between 15% and 35% by weight of the polymer, - between 0.35% and 1.4% by weight of an organic peroxide on a mineral-filler support, - between 0.3% and 1.2% by weight of a stabiliser (thermal agent) for the heat-stabilisation of the material, especially between 300 and 310@C, and - between 0.35% and 1.4% by weight of a stabiliser for the heat-stabilisation of the material, especially between 270 and 280@C.</p> |
