With over 75 years experience as the original manufacturer of the Elmendorf design, the Thwing-Albert Elmendorf Tear Tester is recognized as the worldwide standard.
Based on the classic design, ProTear Testers quickly and accurately measure the tear resistance of sheet materials including paper, textiles, roofing products, film and foils
There is the ProTear Electronic and ProTear Mechanical models
The ProTear Tester offers several capacity configurations ranging from 200 to 25,600 grams, and capacities are changed quickly and easily with augmenting weights. This configuration eliminates the necessity of multiple pendulums and simplifies the testing of different material.
The dart drop tester is an easy-to-use, ergonomically designed instrument used to measure the impact resistance of plastic film, coated paper and other materials.
The Spencer Impact Attachment was developed for use with Thwing-Albert’s Elmendorf Tear Tester. The material is clamped and the pendulum with a probe on the end swings and punctures the material
It provides a convenient method for determining the impact resistance of plastic films and packaging materials under conditions that closely approximate the strain rates that the material is subject to in end-use applications.
Extremely consistent, the Spencer Impact Attachment provides one of the most repeatable methods of testing impact resistance of plastic film.
The air-operated clamping assembly automates the clamping mechanism to ensure an even higher level of accuracy.
