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:

  • Coating surface analysis
  • Fiber impregnation
  • Fracture analysis
  • Polymer and composite analysis
  • Elemental analysis of impurities (down to 0.1 atomic %)
  • Pigment and filler dispersion analysis
  • Image processing for sample feature dimensions (down to 500 nm)

Test specimens must be solids. Cross-sectional surface analysis of a cured material is possible for specimens at thickness less than 3 mm.

Gemini 2 Bohlin Rheometer

Rheological Analysis

 

Our advanced measurements tool, the Malvern Gemini 2 Bohlin Rheometer, can perform standard viscosity measurements as well as polymer formula cure response. Equipped with a thermoelectric heating and cooling plate, it can enable isothermal and programmed temperature schedules, operating from 10 to 120 °C.

ResinLab also utilizes the Gardco Gel Timer and Gardco Hot Pot Gel Timer to generate a gel time value for a 150 cc or 100 cc sample. The Gardco Hot Pot Gel Timer can cure at ambient room temperature, as well as elevated temperature ranging from 65 to 175 °C. The digital Brookfield DV-II Viscometer aids in measuring vicosity.

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. *NOTE* ResinLab is not a certified test laboratory, and UL certifications cannot be provided by ResinLab. This test 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 by measuring samples in a variety of forms, then using an ATR attachment for non-destructive analysis.

Properties include:

  • Surface chemical composition
  • Impurity analysis of a known substance
  • Raw material database for quality assurance

Electrical Property Characterization

 

Our Jandel RM3000 is a 4-point probe that can measure electrical properties of both thin film and bulk materials, including electrically conductive adhesives.

It can be used for characterization of the electrical resistivity (conductivity):

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 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 1” 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.
