Hitachi TM3030 Tabletop Scanning Electron Microscope

Imaging

Using the Hitachi TM3030 Tabletop Scanning Electron Microscope (SEM) with Bruker Energy Dispersive X-Ray Spectroscopy (EDX) attachment, ResinLab is capable of imaging samples at magnifications from 15 to 30,000x, including a chemical analysis of the sample surface – helpful for a variety of applications:

  • Fiber impregnation
  • Fracture analysis
  • Polymer and composite analysis
  • Elemental analysis of impurities (to 0.1 atomic %)
  • Pigment and filler dispersion analysis
  • Image processing for sample feature dimensions (down to 500 nm)
  • Cross-sectional surface analysis of a cured material is possible for specimens with thickness less than 3 mm.

Test specimens must be solids.

Flame Testing

 

We also are equipped to perform UL94 testing, both vertical (UL94V) and horizontal (UL94HB) burn methods, with capability to cast bars at 3 and 6 mm. Please note that ResinLab is not a certified test laboratory, and UL certifications cannot be provided by ResinLab. These tests provides data that support the pursuit of certification.

 

 

Chemical Characterization

 

Our Nicolet iS10 Attenuated Total Reflection Fourier Transform Infared Spectrometer (ATR-FTIR) generates a fingerprint of a sample’s chemical functional groups. The ATR attachment enables non-destructive analysis of the sample.

Properties include:

  • Chemical composition
  • Impurity analysis
  • Comparison of chemicals for quality assurance

Mechanical Property Characterization

 

Our Instron 3369 Universal Tester measures a wide variety of properties across a full spectrum of materials including plastics, metals, ceramics, textiles, adhesives, elastomers, foams, and more. We also have an Instron 3119-615 Environmental Chamber with a temperature range of -100 to +350 ­°C. It is tall enough to allow for tensile testing of materials with a significant elongation to break.

Properties include:

  • Adhesive strength (lap shear, 180° or 90° peel)

Keysight B2985A Resistivity Meter

 

Our Keysight B2985A Resistivity Meter with 16008B Resistivity Cell can measure volume and surface resistivity of electrically insulating materials. Temperature and humidity are measured in tandem with resistivity. The test meter is specified for use from 0 to 55 °C at less than 70 % RH. Values are typically generated at a source voltage of 500 V. A typical sample size is a 4” by 4” square with a thickness of 3 mm. The two faces of the square should be as flat and parallel as possible.

Resistivity measurement ranges are as follows:

  • Volume resistivity [1 x 107 ohm.cm to 4 x 1018 ohm-cm]
  • Surface resistivity [1 x 106 ohm/sq to 4 x 1017 ohm/sq]

Our Keysight E4908AL Dielectric Constant Meter and 16451B Test Cell measures dielectric constant (relative permittivity) and dissipation factor (tan delta). The test cell can be used at temperatures ranging from 0 to 55 °C. The test meter can provide measurements in the frequency range 20 Hz to 300 kHz. To generate accurate and reproducible results, the fixture requires disc-shaped specimens with thickness less than 10 mm, with 2 mm or less ideal, a diameter of 40 to 56 mm (1.6 to 2.2 inches), and surfaces as flat and parallel as possible.

Phenix 4TCE100 10/D149 Dielectric Strength Tester

 

Our Phenix 4TCE100-10/D149 DC Dielectric Strength Tester measures the dielectric strength, or voltage required to generate failure, in insulating materials. We have Type 2 and Type 5 electrodes and a room-temperature oil bath with transformer oil that conforms to ASTM D3487 Type II. The unit can source voltages up to 100 kV with minimum ramp rate of 500 V/s. Samples must be thin and flat with parallel faces. When using the Type 2 electrodes, the specimen must be at least 2” in diameter. Each specimen must also be thin enough to fail within the maximum range of the unit, which usually corresponds to 2 mm or less thickness for the most highly insulating specimens.
