Moisture Monitoring Thermoplastics
Moisture monitoring in Plastics resins and thermoplastic materials with very low moisture content for high-specification moulded components or parts:
The Sartorious LMA100HP Quartz-infrared Moisture Analyser provides results in minutes with a higher 0.005% precision and very low standard deviation for heat sensitive materials with moisture levels as low as 50 ppm.
The LMA100HP conforms to ASTM standard D6980, “Standard Test method for Determination of Moisture in Plastics by Loss in Weight” and results correlate to oven and Karl Fischer coulometric titration.
Practical advantages of being usable in production environments, in using a large 25 – 50 gram sample, with no daily calibration and results in minutes for dynamic quality monitoring and dryer control to optimise throughput and conserve energy costs

Application benefits:
- Drying control in thermoplastics and engineering resins
- Many plastic resins being hygroscopic require monitoring routinely
- Moisture will change continuously during manufacturing
- Excess moisture results in processing issues affecting finished parts quality
- Bad parts need regrinding, reuse or scrapped – wasteful rework
- Resin manufacturers defines Maximum moisture content for optimal processing
- Moisture control reduces symptoms of-
- Drooling
- Bubble formation
- Spraying
- Formation flash
- Surface streaks
- Lower impact and tensile strength
