| Vydyne 21MST is a neat PA66 resin that is designed for extrusion-compounding applications. This general-purpose resin provides excellent viscosity stability against moisture throughout the extrusion process. Vydyne 21MST maintains its medium viscosity through the compounding step. Resistance of Vydyne 21MST to heat, oil and wear is typical of PA66 neat resins.&& |
