Polymer Testing Instruments

The range of products from Thermo Scientific HAAKE, Optical Control Systems(OCS) and Marimex are specifically designed as measurement and material testing equipment for polymer manufacturers and polymer processing. These products provide measurement of: specific heat, no-flow temperature, freeze temperature, degradation temperature, viscosity, thermal conductivity, melt density, pvT behaviour. They also allow for the measurements and recording of in-homogeneities and black specks as well as other physical, chemical and rheological parameters important in the production of polymers.

Marimex Systems

Sensors

The sensor can be mounted in any direction into a reactor, tank, pipe or sample cell. To obtain consistent results, the sensor has to be fully inserted into the liquid. Sensors are manufactured for various viscosity and temperature ranges. To bridge areas of no flow, a non-active extension can be employed. Such a non-active extension is an integral part of the sensor construction and placed between the flange and the probe. A PT100 temperature sensor is integrated in the viscosity sensor for measuring the process temperature.

Software

The Marimex Software provides an easy interface for the configuration of all customer accessible parameters via a PC compatible computer.

Transmitters

A special transmission cable connects the sensor and the transmitter. If the sensor is being mounted in a hazardous area, safety barriers are placed additionally between the transmitter and the sensor. The transmission cable and the safety barriers form part of the calibration. The distance between the transmitter and the sensor can be a maximum of 1,000 meters.

Optical Control Systems – Raw Material Inspection Systems

Chemical & Physical Property

Are designed to test the consistency of the external and physical conditions of the polymer & petrochemical material or exposures in it. These are measurable in gloss-, thickness-, haze loss, partial unevenness or by testing the chemical consistency, additive and density composition of the material by infrared spectroscopy. The systems are applicable on several cast- and blow film lines. As laboratory systems they ensure quality control (QC) and quality assurance (QA), while as on-line systems they improve the process control.

Extrusion / Cast & Blown Film Lines

Are used to produce sample films at a laboratory level to provide the raw material a real time quality control during production process by mounting optical, physical, rheological and chemical control systems.

Impurity / Contamination

Films, plaques, liquids contamination detection in polymers and other substances. The “stand alone” laboratory systems are used in research and development (R&D) centres, or for the quality control (QC) and quality assurance (QA) of polymer film samples. Plaques, liquids and the film surface analysers are used for on-line systems that monitor the polymer quality during the production and improve the process control, and well as for the off-line systems that detect impurities and contamination in slender sheets.

Pellet / Powder

In the laboratory, these systems are used for quality assurance (QA) and quality control (QC) of the pellets and powder, as on-line systems they monitor the polymer quality during the production and improve the process control.

Rheological & Physical Property

Determine on-line viscosity with continuous melt measurements removing the need for manual measurement to be taken. Measuring the environmental stress cracking behaviour classifies polyethylene materials in regards to their slow crack growth behaviour under accelerated conditions.
