CERTIFICATIONS
90% of all manufactured goods produced worldwide are touched by abrasives in some way, in some part of the process. Global leadership in the field of coated abrasive splice technology requires the highest quality products and the strongest technical capabilities. Market reputation, economic risk and safety – much is at stake.
Sheldahl® creates, manufactures, and distributes technically advanced coatings, dry film adhesives, special performance tapes and engineered flexible laminates. Sheldahl® brand technical materials are renowned worldwide. Sheldahl® brand innovative material solutions began in 1955. More than 70% of abrasive belt manufactures in the world choose Sheldahl® brand adhesive and tape products.
Sheldahl’s brand splicing tapes are the undisputed, worldwide leading brand of abrasive belt splicing products. Our scientists and engineers patented Unidirectional tape technology more than 30 years ago. We continue to advance our process and product capabilities:
