Brimrose AOTF-NIR Spectrometers are ideal instruments for measuring and monitoring various components and parameters of polymers. The parameters that can be monitored include mechanical, physical and chemical properties. Typical applications include polyolefins such as polyethylene and polypropylene and other polymers such as rubber, polyamides (nylon), polyesters and various plastics. Measurements can be made on powders, pellets and on melt.
Calibration transfers are possible and if necessary, the calibration can be developed in the laboratory and transferred to the industrial process analyzer. If Brimrose's customized engineering and application support are properly used, a "turnkey" solution can be achieved.
Using the Brimrose 2020 Free Space Spectrometer to measure density in polyethylene powder. A Free Space optical module is mounted to the pipe in which the polyethylene powder is transported. Spectral data is collected during the transport and the density measurement determined.
Chemical Properties
Additives such as Irganox, Irgafos, Tinuin, calcium stearate and zinc searate can be monitored in real-time. Utilizing the Brimrose 3010 Process Analyzer with fiber optic cable and high pressure transmission probes, measurements can be made directly in the extruder or at the rheometer. Other measurements can be obtained on soluble components such as xylene.
Mechanical Properties
An important mechanical property in many polymer applications is Flexural Modulus. In the picture to the left a Brimrose Free Space spectrometer, mounted in the transport line and collects spectra. A model is applied to the spectra and Flexural Modulus is determined. The resulting data can then be used by the DCS. Brimrose AOTF-NIR Spectrometers are "adaptable" to real process environments via varying types of electronic communication:
Ethernet communication
Modbus protocol (RS232/485/422)
4-20mA outputs
Other factors that can be analyzed are:
Physical property:
Intrinsic (pertaining to the essential nature of a thing) Viscosity (IV)
Mechanical property
