Universal Tensile Testers for Rubber & Polymers

Universal Tensile Tester for Rubber & Polymers

Comprehensive Mechanical Property Evaluation

In the rubber and polymer industry, understanding a material's physical strength is just as crucial as its chemical formulation. EKTRON TEK's Universal Tensile Tester Series provides highly accurate, multi-functional platforms designed to subject vulcanized rubber, plastics, and composites to rigorous mechanical stress evaluations.

Multi-functional Capability: Perform tension, compression, tear, and adhesion tests on a single machine.
Broad Applications: Ideal for evaluating O-rings, nylon cords, steel wires, belts, and dynamic seals.
Precision Engineering: Built to meet strict global testing standards with highly accurate load cells and drive systems.

Frequently Asked Questions: Mechanical Testing Basics

What is the difference between Tensile, Compression, and Tear testing? ▼

Tensile testing pulls a sample apart to measure its ultimate strength and elongation. Compression testing pushes down on a sample to evaluate its resistance to crushing and its deflection properties. Tear testing measures the force required to propagate a pre-existing cut or slit in a fabric or rubber sample. A universal tester can perform all three simply by changing the grips and software parameters.

Why is grip and die selection important for tensile testing? ▼

Rubber and polymers behave differently under stress compared to metals; they thin out dramatically as they stretch. Using the correct pneumatic or self-tightening grips prevents the sample from slipping or breaking prematurely at the jaw face. Similarly, using standard sample cutting dies (like dumbbell shapes) ensures the stress concentrates in the proper testing zone, guaranteeing standard-compliant data.
