EVA Foam Properties Table (small)


Tear Resistance is the force required to rip a sample of plastic film, sheeting or rubber product. An unnicked 90-degree angle specimen is used to measure the tear resistance of foam.

Calculate the resistance to tear from the maximum force registered by the testing machine and the thickness of the specimen, and express as the force in newtons (or kilogram, pounds-force) required to tear a specimen 1 m (or 1cm, 1 inch) in thickness.

Tear Resistance = F / t

F = force, N (kg, lbf).
t = specimen thickness, m (cm, inch).
