Description
AYSM
Yellow stress relief void filling mastic is used on connectors and at screen cuts when doing medium voltage(MV) joints and termination installations.
Features include excellent adhesive and sealing capabilities, weather resistance, anti-aging, mildew, chemical resistance and excellent dielectric properties.
ARAM
Red anti-track mastic is used in MV termination installations to ensure a watertight seal on breakout boots, anti-track tubing and on lugs.
Features include excellent adhesive and sealing capabilities, weather resistance, anti-aging, mildew, chemical resistance and excellent dielectric properties.
ABFM & AGFM
Grey & black butyl self amalgamating sealing mastic is suitable for LV and MV applications. It is used for sealing and waterproofing of electrical installations such as joints and terminations, as well as in telekom installations.
Features include excellent adhesive, sealing, electrical and anti-aging properties and is UV resistance.
