Glass-filled Nylon, or PA6-GF, employs PA6 (polyamide 6) as the basic compounds. Polycaprolactam (PA6) is another name for Nylon 6 or PA6. PA6-GF performs well at low temperatures and has strong toughness and impact resistance. It also has high dimensional stability and moisture absorption. Glass fiber content in PA6 GF range from 20% to 60%. Strength and rigidity increase with increasing glass fiber content, while toughness and impact resistance decrease.
