Why is it important to distinguish the quality of granule and polymer compound?
Appearance signs of polymer granule quality
Uniformity of shape and size
Uniform color without stains
Absence of impurities and foreign particles
Examination of the smell of granules and compounds
The role of raw materials in the final quality
Technical tests to determine the quality of granules and compounds
Melt flow index
Density and density
Moisture test
Mechanical strength
Thermal stability
The importance of the production process in the final quality
packaging and storage; Part of quality
How to distinguish the quality better when buying?
- Consignment sampling and appearance uniformity check
- Technical specification sheet request
- Color and texture stability check
- Performance test on the actual device
- Paying attention to the manufacturer's history and quality stability in different orders
- Comparison of several samples in terms of processability and final output
The difference between high-quality and low-quality granules in the production line
- Fluctuation in piece weight
- Creation of bubbles or cavities
- Reduction of product strength
- Unwanted color change
- Increased production waste
- Frequent line stops
The role of polymer compounds in improving properties
- Uniform mixing
- Appropriate distribution of additives
- Stability in color and properties
- No problems in the process
- Compatibility with the final application
