MAVEN NF 421
- Chemical Family
- Polyesters
Selenis Maven NF 421 is an amorphous copolyester that has been specifically developed for the extrusion of heavy gage sheets, allowing for high thicknesses without crystallization occurring. Selenis Maven NF 421 is the best possible solution when exceptional clarity, surface gloss, and neutral edge color are required. Selenis Maven NF 421 is recommended when a very demanding performance and outstanding toughness are essential, such as, ultimate impact strength at low temperatures and good chemical resistance to detergents and other household cleaning agents. Thanks to its inherent toughness, sheets produced from Selenis Maven NF 421 may be down-gaged without compromising performance. Cost-savings are possible given that there is no need to pre-dry the sheets. Selenis Maven NF 421 is easy to process on standard extrusion lines. Sheets made with Selenis Maven NF 421 may be easily thermoformed, cold-bent, drilled, sawed, screwed, adhesive bonded, routed and personalized though different methods of decoration. All Maven grades are BPA and styrene free.

- Technical Details
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.
