The chemical and physical properties of nylon Pa6 are very similar to the polyamide nylon 66, but it has a lower melting point and a wider processing temperature range. Impact and resistance of nylon 66 material
The solubility is better than PA66, but it is also more hygroscopic. Since many quality properties of plastic parts are affected by hygroscopicity, PA6 design is used
This should be fully taken into account when considering the product. In order to improve the mechanical properties of PA6, various modifiers are often added. Fiberglass is the most common
Additives, sometimes synthetic rubbers like EPDM and SBR, are added to improve impact resistance. Polyamide Nylon 6 Shrinkage of Additive-Free Products
Between 1% and 1.5%. Adding glass fiber additives reduces shrinkage to 0.3% (but slightly higher perpendicular to the process).
Shrinkage of molded components is primarily affected by the crystallinity and hygroscopicity of the material. The actual shrinkage rate also depends o…
