Mullen® Testers manufacturers the industry-renowned Mullen Burst Tester used worldwide to measure the burst strength of paper, textiles and board fibers in accordance with ASTM, TAPPI and international standards. What started as an innovative contribution to the paper industry eventually served to define the "standard grades" in commerce - and when it comes to quality control, our tester is an integral part of any well-equipped lab.
With pulp and paper products, the Mullen Burst Tester measures the material's physical strength and fiber bond. For textiles, the Mullen Burst Tester is used to guage the fabric's strength along with the immediate or eventual effects of dyes, chemicals, and processes. It also demonstrates the results of wear, age and environment, and evaluates the comparative strength of alternative fibers. In addition to these materials, we've extended our testing capabilities to include:

Mullen also offers a Hydrostatic Tester that measures the resistance of material to water-for geotextiles and other such products as raincoats, umbrellas, and ski & swim attire. Our Deflectometer Tester gauges the distension and grain cracking of soft leather material for shoe uppers, garments, gloves, and upholstery.
