Purpose and User

This is a pack of 100 rolls of blue vinyl electrical tape designed for general-purpose insulation. Each roll measures 1/2 inch wide by 20 feet long with a 7 mil thickness. The rubber-resin adhesive bonds reliably in temperatures from 32 to 221 degrees Fahrenheit. It suits electricians, maintenance crews and automotive technicians who need consistent colour coding.

Build and Handling

The vinyl backing resists abrasion and moisture while the rubber-resin adhesive provides immediate grip on wire and cable. Supplied as continuous single-sided rolls, the tape unwinds cleanly for quick wrapping and splicing. Blue colour allows easy circuit identification in panels or harnesses. The 7 mil thickness balances conformability with mechanical protection for everyday use.

Voltage and Temperature Limits

Rated for 600 volts, the tape meets standard low-voltage insulation requirements. Performance is guaranteed only between 32 and 221 degrees Fahrenheit, so it is not suited for extreme cold or high-heat environments. Users must verify that local codes accept this rating for their specific application. The product carries no additional certifications beyond the stated voltage and temperature range.
