Nicolet Avatar360 Taber 5150 Rheometer

Fourier Transformed Infrared Spectroscopy utilizes an infrared signal to excite the functional groups of an organic molecule, resulting in a unique spectrum that is used to identify the purity and structure of a compound. The attenuated total reflectance (ATR) accessory requires no sample preparation.

Applications:

  • Quality control of rubber chemicals
  • Identification of unknowns
  • Characterization of rubber compounds
  • Quality control of PTFE
  • Quality control of rubber compounds
  • Instrument output sample

Used to evaluate to abrasion.

Applications:

  • Abrasion resistance of rubber compounds

An oscillating disc rheometer that measures the viscosity, cure time and final cure state of rubber compounds.

Applications:

Perkin Elmer DSC 7

Perkin Elmer DSC7

Differential scanning calorimetry measures the
differences in the amount of heat required to
increase the temperature of a sample and a reference
as a function of temperature.

Applications:

  • Determination of Tg, Tm and crystallinity of polymers
  • Degree of cross link, cure characteristics
    and heat of reaction of polymers
  • Quality control of polymers and PTFE
  • Instrument output sample
