Elastack material is so soft, it seals out air on contact to form a suction bond. Adherence releases easily and is never sticky, making Elastack tapes ideal to prevent sliding and enhance grips. The ultra soft grade is the most adherent, transparent, and softest, but is not intended for use above room temperature. The medium grade is firmer, translucent, and durable at elevated temperature (dishwasher safe to 220°F/104°C). The tape is 20mm (0.8") wide and 3.6m (12') long. Latex free.
