Scotch Vinyl Mastic Pads 2200 are pre-cut insulating pads that protect electrical connections. Rubber-based insulating compounds are laminated to a flexible, high-quality PVC backing that seals out moisture and insulates connections up to 600 volts. The vinyl resists ultraviolet light, acids, alkalis, corrosion and moisture, making the tape a better choice for indoor and outdoor applications. It protects in extreme weather conditions, withstanding temperatures up to 176 °F (80 °C). These durable pads are self-fusing with a rubber-based, pressure-sensitive adhesive that provides excellent hold and mechanical protection. Each pad has a 5-year shelf life and measures 6-1/2 in x 4-1/2 in. Compatible with all common solid dielectric cable insulation, protect, insulate and safeguard your electrical connections with the Scotch® Vinyl Mastic Pads 2200 from 3M.
