The chemical and physical properties of PA6 are simir to that of PA66. However, its melting point is low and the process temperature range is wide. Its impact resistance and solubility are better than PA66, but its hygroscopicity is also stronger. Because many quality characteristics of pstic parts are affed by hygroscopicity, it should be fully considered when using PA6 to design products. In order to improve the mechanical properties of PA6, various modifiers are often added. Gss fiber is the most coon additive, sometimes in order to improve the impact resistance of synthetic rubber, such as EPDM and SBR. For products without additives, the shrinkage of PA6 is between 1% and 1.5%. The addition of gss fiber additive can reduce the shrinkage to 0.3% (but it is slightly higher in the dirion perpendicur to the process).
PA6的化学物理特和PA66很相似,然而,它的熔点较低,而且工艺温度范围很宽。它的抗冲击和抗溶解比PA66要好,但吸湿也更强。因为塑件的许多品质特都要受到吸湿的影响,因此使用PA6设计产品时要充分考虑这一点。为了提高PA6的机械特,经常加入各种各样的改剂。玻璃纤维就是常见的添加剂,有时为了提高抗冲击还加入合成橡胶,如EPDM和SBR等。对于没有添加剂的产品,PA6的收缩1%到1.5%之间。加入玻璃纤维添加剂可以使收缩率降低到0.3%(但和流程相垂直的方向还要稍高一些)。
The mold temperature of PA6 processing is 80-90 ℃, and the mold temperature has a significant eff on the crystallinity, which in turn affs the mechanical properties of pstic parts. The crystallinity is very important for structural parts, so it is recoended that the mold temperature be 80-90 ℃. For thin-walled and long process parts, higher mold temperature is also recoended. Increasing mold temperature can improve the strength and stiffness of pstic parts, but reduce the toughness. If the wall thickness is greater than 3 , it is recoended to use a low-temperature die with 20-40 ℃. For gss fiber reinforced materials, the mold temperature should be higher than 80 ℃.
BASF has a long history of trade with China, more than a century ago. As r back as 1885, BASF, which was founded only 20 years ago, has already sold the mous textile dye in to China, making China the most important market of BASF magenta outside Germany. In addition to providing dyestuffs for China, BASF has been expanding its product range. Today, BASF has a wide range of products. The list of products produced by joint ventures or imported into the Chinese market from other pces is simir to a chemical boratory manual. It can fully refl the business scope of BASF: pstics, chemical fiber intermediates, fertilizers, industrial chemicals, fine chemicals and textile and leather chemicals.
PA processing due to iature technology can reduce the product, or can not meet the product requirements after molding, so some technical personnel of our company soe the processing technical problems for customers, because of the different model performance of PA6, the price will be different, so the online price is only reference price, the actual price please consult online or call to negotiate! Jinghong pstic will serve you wholeheartedly!
