Polyamide-6 (PA6)
Product Features
The chemical and physical properties of PA6 are very similar to those of PA66; however, it has a lower melting point and a wider processing temperature range. Its impact resistance and solubility resistance are better than those of PA66, but its moisture absorption is also stronger. Since many quality characteristics of plastic parts are affected by moisture absorption, this should be fully considered when designing products with PA6. To improve the mechanical properties of PA6, various modifiers are often added. Glass fiber is the most common additive, and sometimes synthetic rubber, such as EPDM and SBR, is added to enhance impact resistance. For products without additives, the shrinkage of PA6 is between 1% and 1.5%. Adding glass fiber additives can reduce the shrinkage rate to 0.3% (but it is slightly higher in the direction perpendicular to the flow).
