Peel Adhesion Methods

Vartest upgraded our Instron with a 90-degree peel fixture earlier this year.  It allows us to now perform the following methods:

  • ASTM B571: Standard Practice for Qualitative Adhesion Testing of Metallic Coatings
  • ASTM D429 Method B: Standard Test Methods for Rubber Property—Adhesion to Rigid Substrates
  • ASTM D3330 Method F: Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape
  • ASTM D6252: Standard Test Method for Peel Adhesion of Pressure-Sensitive Label Stocks at a 90° Angle
  • ASTM D6862: Standard Test Method for 90 Degree Peel Resistance of Adhesives

Puncture Propagation Tear Testing via ASTM D2582 at Vartest

Vartest tests coated and uncoated fabrics used primarily in Personal Protective Equipment (PPE) using ASTM D2582. This test is often used in the medical and military markets and Vartest also has the capacity to provide anti-bacterial, moisture management, physical, flammability, washing and dry-cleaning tests that performance specifications calling for ASTM D2582 often include.

Vartest Laboratories supported the Drexel effort to bring the National Network for Advanced Functional Fabrics Manufacturing to Philadelphia

“The U.S. Department of Defense has tapped Drexel University as a key leader in the creation of a $75 million national research institute that will support American textile manufacturers in bringing sophisticated new materials and textiles to the marketplace. [1]”

Vartest looks forward to being a technical resource for AFFOA projects, as part of the Fabric Innovation Initiative (FIN). This resurgence of cutting-edge textile technology in the North East harkens back to the birth of the US textile industry in the North East and the development of a significant textile technology department at MIT, but with a pleasant and welcome, modern high-tech twist.
