Other than fiber-reinforced polyamide 6, the unreinforced nylon type 6 produced by Anmei, one of the professional nylon 6 suppliers/manufacturers, is also divided into toughened, heat-resistant, alloy and flame-retardant modified PA6.
Nylon 6 (PA6) is made up of a group of 6 carbon atoms. PA type 6 plastic has a low melting point, a wide process temperature range, and strong impact resistance and solubility resistance. Both high tensile strength and super-high tensile strength Nylon6 (PA6) have excellent flexibility, impact resistance, low-temperature resistance, wear-resistance and dimensional stability of the nylon 6 material. PA6 flame retardant is mainly achieved by adding halogen-free flame retardant and halogen flame retardant to achieve the flame retardant effect. The physical and mechanical properties of these nylon 6 plastic materials are comparable to similar products in Europe and America. This series of halogen-free flame retardant products comply with RoHS environmental protection standards. The nylon 6 PA6 price provided by Anmei is reasonable and high-quality nylon 6 plastic is available.
The nylon 6 PA6 plastic material we offer including the following three types: high tensile strength type, heat stabilized type and nylon flame retardants. Click below to get more!
The main varieties of nylon are nylon 6 (PA6) and nylon 66 (PA66), which are absolutely dominant. The difference between the two is as follows.
1. The basic difference in physical properties.
Nylon PA6 is poly-caprolactam, while nylon 66 PA66 is poly-adipic acid adipamide, PA66 is 12% harder than nylon PA6. PA6's chemical and physical properties are very similar to PA66, however, it has a lower melting point and a wide range of process temperatures. Nylon 6 plastic has better impact resistance and dissolution resistance than PA66, but it is also more hygroscopic. PA66 is a semi-crystalline - crystalline material with a higher melting point, which can also maintain strong strength and stiffness at higher temperatures.
2. Product performance difference
Polyamide nylon 6 has excellent thermal stability, high heat resistance; good dimensional stability; high surface quality; good anti-warping properties; PA66 has excellent wear resistance, good high impact resistance and good dimensional stability.
3. Use difference
Nylon PA6 is generally used in automotive parts, mechanical parts, electronic and electrical products, engineering parts, etc. PA66 is more widely used in the automotive industry, instrument housings and other products that require impact resistance and high strength requirements, such as marine propellers, gears, rollers, pulleys, rollers, impellers in pump bodies, fan blades, high-pressure sealing enclosures, valve seats, gaskets, bushings, various handles, support frames, wire packages Inner layer, etc.
4. Injection molding process difference
Drying process (If the material is sealed before processing, then there is no need to dry. If the storage container is opened, then it is recommended to dry the process in hot air at 85℃. (If the humidity is greater than 0.2%, vacuum drying at 105°C for 12 hours is also required.)
Melting temperature (230~280℃ for PA6, 250~280℃ for reinforced nylon; 260~290℃ for PA66. (275~280℃ for glass-modified products, melting temperature should be avoided higher than 300℃.)
Mold temperature (80~90℃, the mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product)
Injection pressure (usually at 750~1250bar, depending on the material and product design.)
Injection speed (high speed (to be slightly reduced for reinforced nylon))
Runners and gates (solidification time is very short, so the location of the gates is very important)
Nylon flame retardants of polyamide nylon 6 are divided into two categories: halogen series and halogen-free flame retardants according to whether they contain halogen.
▲ Halogen-based flame-retardant nylon PA6 has good thermal stability and good fluidity during processing. It is mainly suitable for the production of small, thin-walled, complex-structured components, such as switches, reconnectors, and plug-ins;
▲ Halogen-free flame-retardant nylon PA6 is used in flame-retardant reinforced nylon varieties with strict environmental protection requirements. Phosphorus flame-retardant nylon has good mechanical properties and is suitable for electronic and electrical parts.

Polyamide has poor impact strength at low temperature and dry statement and has a large water absorption rate. In response to these shortcomings, the tensile strength polyamide of Anmei is adding a certain amount of rubber or elastomer to nylon to double its impact strength. And more is toughened by the elastomer. It can effectively improve the impact resistance and low-temperature performance of our nylon 6 plastic material. And toughening by elastomer can effectively improve the impact resistance and low-temperature performance of nylon PA6.
After toughening:
1. The low-temperature toughness and impact resistance of Anmei Nylon 6 products are significantly improved, and the rigidity is significantly reduced;
2. The surface finish of nylon PA6 has a certain decrease;
3. Conducive to reducing water absorption;
4. Decreased processing fluidity;
5. The molding shrinkage rate increases.
