Scotch® 2234 tape uses a vulcanized CSM rubber backing that is resistant to abrasion and stays intact even when exposed to various forms of chemical and environmental exposure. The flame-retardant mastic inner layer adheres strongly to heavy duty cable jackets and seals against moisture to ensure a powerful seal that keeps them safe. This repair tape is suitable for layering over cables used in different industries, including maintenance and repair services, commercial and residential construction, heavy industries, irrigation and wind energy.
