The Applied Technical Services Family of Companies (ATS FoC) measures polymer viscosity according to ISO 1628-1, helping companies maintain compliance and monitor batch quality.
How Does ISO 1628-1 Help Determine Polymer Molecular Properties?
ISO 1628-1 establishes the standard for determining polymer viscosity using capillary viscometers.
When no specific standard exists, ISO 1628-1 provides a general method to measure an organic polymer’s intrinsic viscosity, reduced viscosity, and K-value. These measurements offer insight into the polymer’s molecular properties.
Why is Assessing Polymer Viscosity Important?
A material’s molecular weight significantly impacts its viscosity. Larger, heavier molecules tend to increase solution viscosity, which we can measure to determine their general molecular weight. This information is valuable for several applications, including:
- Detecting Batch Variation
- Determining Molecular Weight Changes
- Distinguishing Polymer Alterations
- Optimizing Manufacturing Processes
- Research and Development
- Quantification of Molecular Weight Degredation
Which Industries Rely on ISO 1628-1?
ISO 1628 applies to many industries that rely on polymer viscosity for quality control and product development, including:
- Plastic & Polymer Manufacturing
- Automotive Industries
- Packaging Manufacturing
- Aerospace Industries
Testing polymer products to applicable standards supports product conformance. Working with qualified testing labs ensures accurate and reliable results.
