NYMAX™ BIO BIO-BASED POLYAMIDE SOLUTIONS PROCESSING GUIDE 1 NYMAX BIO Formulated in glass fiber-filled or unfilled materials, Nymax™ BIO formulations utilize between 16 and 47 percent natural filler from renewable plant-based raw materials, reducing the carbon footprint value significantly at the beginning of the product lifecycle. These highly engineered formulations deliver comparable performance to traditional PA66 glass fiber- filled materials, plus the bio-derived solutions offer lower warpage and have excellent surface appearance and colorability. Regrind is not suggested—glass fiber reinforce material will lose strength after regrind Mold Design Recommendations Gates 1.
