Testing Capabilities

Analytical testing performed by our laboratory includes:

  • Chemical composition
  • Tribological
  • Rheological
  • Mechanical
  • Thermal

When required, we also design product test stands.

Our laboratory uses a robust spectrum of plastic and elastomer test methods to ensure that material properties meet specifications. Conducted applicable standards such as ASTM, DIN, ISO, JIS; these tests include:

Hardness – Durometer testing for control purposes, since no simple relationship exists between hardness and any fundamental physical property.

Tensile properties – Physical properties for tensile strength, ultimate elongation and modulus (tensile strength at a given elongation).

Thermal properties – Measures the performance of the material in a broad range of temperatures considering transition temperatures, coefficient of thermal expansion, and thermal stability.

Deflection temperature – A comparison of the relative behavior of various materials.

Compressive properties – Useful in determining specifications for different grades of materials, and in conjunction with other data to determine overall strength.

Specific gravity – The ratio of the density of a material to the density of a reference substance, generally water. It is used as a quality assurance measurement to assure lot-to-lot consistency.

Tear resistance – A relative measure of a material's resistance to tear.

Compression set – A measure of a material's retention of elastic properties, particularly useful with squeeze-type seals

Immersion testing – Provides insight regarding the effect of a particular medium on a specific material.

Heat aging – Used to determine a material's deterioration due to dry heat.

Adhesion – Primarily a quality control test for coating quality and application.
