Adhesive Applications

Recently, more and more manufacturers have learned of the superiority of structural adhesives to conventional joining techniques. As a result, the amount of structural adhesive applications has grown. Today, adhesives bond materials across every industry, including:

  • Automotive
  • Aerospace
  • Electronics
  • Medical
  • Athletics
  • Construction.

Polymer Adhesive Testing

Most structural adhesives today are based on polymers, long chainlike molecules in which the links are smaller molecules called “mers,” and the backbones are carbon atoms. These polymers become adhesives when combined with various additives that improve their ability to adhere to different surfaces. We test these adhesives in our polymer testing lab, including thermosets and thermoplastics. Thermosets are polymer resins that are cured, set, and hardened into a permanent shape. Thermoplastics are polymers that soften when heated and harden when cooled.

Organic Polymers

Rely on NSL Analytical’s team of experienced specialists for organic polymers testing for mechanical properties and capabilities to analyze failed parts.

Organic Polymers Testing

Polymers are high-molecular-weight organic compounds formed by long chains of simple molecules called monomers on a backbone of carbon atoms. Polymers are classified as thermosets or thermoplastics. Thermosets are polymer resins that form permanent shapes when heated because chemical crosslinks form between chains. Thermoplastics, on the other hand, can be repeatedly shaped and melted, as no chemical crosslinking takes place.

Polymer Testing Expertise

NSL Analytical’s experienced team of polymer specialists knows that the typical polymer part is much more complex than a simple thermoset or thermoplastic. Virtually every polymer product also contains fillers, binders, plasticizers, fire retardants, and other additives, and is also very likely to be alloyed with other polymers. In many cases, polymers serve as the matrix material for composites, and may be reinforced with fibers of carbon, glass, or metal – or with particles of ceramic, metal, carbon, or other materials.

These specialties use a variety of sensitive analytical instruments and techniques to determine physical and chemical characteristics of materials, including the detection of restricted chemicals such as phthalate plasticizers and brominated fire retardants (PBB and PBDE.) They test for mechanical properties such as strength and stiffness, and for physical characteristics such as melting point and crystallization temperature. They can also provide elemental analyses to determine that the polymers do not contain mercury, nickel, lead, or other restricted elements.

The depth of the team’s experience also enables them to analyze failed parts to find the root cause of failure; and to reverse-engineer products to determine not only the constituent materials, but also how parts were fabricated.


NSL Analytical provides comprehensive testing and identification of alloys and their chemical properties. Our certified team of specialists perform an array of metallurgical testing and analysis with reliable results for your material.

Composites serve an important function as versatile material solutions for a number of industries. As such, there are many possible materials present in their properties, which must be thoroughly tested to determine their use for a specific application. 

Our team of expert scientists execute a number of testing methods to determine the strength, corrosion resistance, impact capabilities and more for your operation. NSL’s analyses deliver repeatable, reliable results for a wide range of composite materials to be used in virtually every industry. 

Composite Testing

Because of the presence of different materials and laminates that are part of a composite part’s makeup, several types of metallurgical tests may be applied for redundancy. This comprehensive testing will also accurately determine the performance, safety and material data for composites, and may include:

  • Compression testing
  • Tensile testing
  • Compression after impact testing
  • Material verification and certification
  • Shear testing
  • Fatigue testing

Along with NSL’s roster of complete testing services, our team of experts can determine the properties and characteristics of your composites for safe, compliant use in a wide variety of applications.

Maintenance, Repair, and Overhaul

MRO includes a diverse range of materials and processes from brazing and welding to repair parts to ceramic thermal spray to repair coatings.  It also is beginning to include more advanced additive manufacturing processes including laser blown powder directed energy deposition as well as just in time spares made using advanced wire fed DED and laser powder bed fusion.

The MRO industry is critical to the commercial and defense supply chains as they maintain and sustain aircraft, engines, power plants, ships, and other critical infrastructure.

NSL services support MRO focused organizations through process verification and validation, materials chemistry testing to specification, metallography, and failure analysis when needed.
