WMA101 is a type of sioplas method moisture cured insulation material which is applied for electric wires and cables. It has advantages of excellent electrical insulation properties, anti-ageing ability and tensile strength, the highest continuous working temperature is 90℃ and excellent low-temperature brittleness property.
WMA101 must be mixed with the catalyst B material (WMA101: B=95:5).
