Peel Strength Testing
National Technical Systems (NTS)
Peel Strength Testing is the average load per unit width of bond line required to separate bonded materials where the angle of separation is 180⁰. Peel testing is one way to characterize adhesive bonds. It is used extensively to evaluate the bonding strength of tape, adhesives and flexible substrates, including rubber, films, biomaterials, dental materials, medical packaging and consumables. Typical tests involve peeling two bonded flexible adhered from each other, or peeling a flexible bonded adhered from a rigid substrate. Peel tests are usually conducted at a constant rate at various angles, with 90° and 180° being the most common. Parameters such as peak peel load, average peel strength and statistical measures of peel strength variability are typically used to characterize behavior under peel loading.

Mechanical Testing Services
The physical and mechanical testing of a product comprises a critical part of the product and development process. Applied physical force such as vibration, shock stresses, and strain can reveal the inelastic behavior of the material. Mechanical testing allows the product developers to understand the product better, identify vulnerabilities, and establish stronger quality control. Mechanical testing employs a variety of strength tests that can determine the suitability of a material or component for the intended application. It measures characteristics such as elasticity, tensile strength, elongation, hardness, facture toughness, impact resistance, stress fracture, and the fatigue limit.
