ナイロン 6 としても知られる PA6 は、半透明または不透明な乳白色の粒子で、熱可塑性、軽量、優れた靭性、耐薬品性、耐久性の特性を備えており、自動車部品、機械部品、電子および電気製品、エンジニアリングアクセサリなどに一般的に使用されています。製品。

PA6 の化学的および物理的特性は PA66 の特性と類似しています。ただし、融点が低く、プロセス温度範囲が広いです。耐衝撃性と溶解性は PA66 よりも優れていますが、吸湿性も優れています。

プラスチック部品の多くの品質特性は吸湿性に影響されるため、PA6 を使用する製品を設計する際には吸湿性を十分に考慮する必要があります。PA6 の機械的特性を改善するために、さまざまな改質剤が添加されることがよくあります。最も一般的な添加剤はグラスファイバーであり、耐衝撃性を向上させるために合成ゴムが添加されることもあります。

PA66 plastic has a higher melting point in polyamide materials. It is a semi-crystalline - crystalline material. PA66 can also maintain strong strength and stiffness at higher temperatures. PA66 plastic still has hygroscopic properties after molding, the extent of which mainly depends on the composition of the material, wall thickness and environmental conditions. The effect of hygroscopicity on geometric stability must be considered in product design. In order to improve the mechanical properties of PA66, a variety of modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber is added to improve impact resistance. PA66 plastic is less viscous and therefore flows well (but not as well as PA6).

PA66 (polyamide 66 or nylon 66), compared with PA6, PA66 is more widely used in the automotive industry, instrument housing and other products requiring impact resistance and high strength requirements.

Widely used in the manufacture of machinery, automobile, chemical and electrical equipment parts, such as gear, roller, pulley, roller shaft, pump body impeller, fan blade, high pressure sealing, valve seat, gasket, bushing, various handles, support frame, wire package inner layer, etc.

PA66 plastic raw material is translucent or opaque opalescent crystalline polymer, with plasticity. Density 1.15g /cm3. Melting point 252℃. Embrittlement temperature -30℃. Thermal decomposition temperature is greater than 350℃. Continuous heat resistance 80-120℃, balanced water absorption rate of 2.5%. Resistant to acid, alkali, most aqueous inorganic salts, alkyl halides, hydrocarbons, esters, ketones and other corrosion, but easy to phenol, formic acid and other polar solvents. It has excellent wear resistance, self lubricity and high mechanical strength. But the water absorption is larger, so the dimensional stability is poor

PA66 is a variety of PA series with high mechanical strength and wide application. Due to its high crystallinity, it has high rigidity and heat resistance.
