Nashua 357 Premium Grade Duct Tape is the duct tape professional contractors choose when they require a consistent trouble-free product. It has high tensile strength and is very durable. Its clean release resists delamination and it conforms to a wide variety of surfaces. It also tears straight resists curling and has outstanding performance over a wide temperature range. Low VOC Content and can contribute toward satisfying EQ Credit 4.1 (Low Emitting Materials) under LEED. Nashua 357 uses include HVAC (heating ventilating air conditioning) and refrigeration applications. Also asbestos removal applications sealing of seams and joints in metal air handling systems sand and media blasting applications and the manufacture of flexible duct equipped with metal collars. It is a great tape for bonding protecting holding repairing patching packaging bundling and motorsports. Also please note that Nashua 357 comes to our converter in log roll format (that is why the tape can be offered in non-standard widths) and because of that rolls will more often than not ship on plain white cores. This tape was featured in the MythBusters Duct Tape Hour episode. It offers close to the strength of Gorilla tape yet is easier to work with and handle since only 13 mils thick instead of 17 mils like Gorilla tape. Its thick adhesive also has a viscosity that allows it to easily flow over irregular surfaces. Country of Origin: United States.
