Specifications
This table contains Selenis Maven NF 421 characteristics and their methods of analysis. Some properties are subject to limits; others are presented with their typical values. Small variations of the typical values do not affect the application performance of the polymer.
All properties are measured under laboratory conditions by the analytical method shown. Limits in these specifications are applicable only to data obtained by the referenced test methods. Different methods or conditions of analysis may give rise to different values. A Certificate of Analysis, with representative average values of certain properties, can be sent to the customer when requested.
Processing
In order to obtain maximum product performance, Selenis Maven NF 421 should be dried to achieve a moisture level below 0.004 % (40 ppm) before processing. Typical drying requirements include a dehumidifying air hopper dryer with regenerative desiccant beds, -40°C dew point air, and 60 - 65°C drying temperature for at least 6– 8 hours. During drying it is important that the temperature of the processed air does not exceed 70°C in order to avoid chips sticking together in the hopper of the dryer.
Typical processing temperatures are between 180°C to 250°C and should be chosen in function of the needs of the transformation technology.
Safety & Health
- Health and Safety Consideration
Read and follow all information presented in the Safety Data Sheet (SDS) for this product.
Storage & Handling
- Storage and Handling Conditions
- Selenis Maven NF 421 is an inert material in storage and no hazards are likely to arise; however the polymer should be stored in an area properly protected from risk of fire.
- Selenis Maven NF 421 should be stored in the original container, tightly closed in a dry, cool and well-ventilated place. Avoid direct light contact if the container is stored indoors.
