Characteristic:
The chemical and physical properties of nylon-6 are very similar to those of nylon 66. It has a lower melting point and a wide process temperature range. It has better impact and dissolution resistance than nylon 66 plastic, but is also more hygroscopic. Because many quality characteristics of plastic parts are affected by hygroscopicity, it is important to take this into account when designing products using nylon 6. In order to improve the mechanical properties of nylon 6, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubbers such as EPDM and SBR are added to improve impact resistance. For products without additives, the shrinkage of nylon 6 plastic material is between 1% and 1.5%. Adding glass fiber additives can reduce the shrinkage to 0.3% (but slightly higher in the direction perpendicular to the process). The shrinkage of molding assembly is mainly affected by the crystallinity and hygroscopicity of the material. Actual shrinkage is also a function of part design, wall thickness and other process parameters. Nylon 6 injection drying treatment Since nylon 6 easily absorbs moisture, special attention should be paid to the drying before processing. If the material is supplied in waterproof packaging, the container should be kept tightly closed. If the humidity is greater than 0.2%, it is recommended to dry in hot air above 80C for 16 hours. If the material has been exposed to air for more than 8 hours, vacuum drying at 105C for more than 8 hours is recommended. Nylon 6 injection molding process parameters Melt temperature: 240-250°C, 250-280°C for reinforced varieties.
