PA12原料颗粒
聚酰胺PA12的快速发展离不开其优良的结构：聚酰胺PA12的分子主链含有大量极性酰胺基，这使得聚酰胺分子具有强大的作用力，并能形成氢键（一般氢键密度越大，机械强度越好，碳原子数越多，强度越差），同时使聚酰胺PA12分子排列整齐，结晶度好；聚酰胺PA12分子主链段还含有*，这使聚酰胺具有柔性，并会影响聚酰胺PA12的熔点和玻璃化转变温度（Tg）；此外，聚酰胺大分子的主链端含有氨基和羧基。反应性很容易改变。与其他材料相比，具有酰胺基（-CONH-）结构的聚酰胺PA12具有一系列优异的性能。聚酰胺PA12树脂是一种综合性能优异的材料，但它也有明显的缺点，如温度敏感性、吸水性对尺寸稳定性影响很大，低温韧性差。通过化学或物理方法进行改性可以大大提高其性能。例如，通过添加玻璃纤维材料，可以大大提高吸水率和尺寸稳定性，提高树脂的强度和韧性；各种合金可以通过与其他聚合物混合来代替金属，如木材等传统材料
聚酰胺12弹性体（尼龙12弹性体）是一种热塑性弹性体（TPE）材料。它是一种嵌段聚合物，包括PA12段和聚醚段（聚醚嵌段酰胺）。富含PA12的产品具有PA12的主要性能，随着聚醚含量的增加，弹性体的性能变得更加明显：即聚合物变得更柔软，具有更高的低温冲击强度。由于其优异的性能，这种聚合物在许多应用中不可或缺

Product Details
PA12 raw material particles
The rapid development of polyamide PA12 is inseparable from its excellent structure: the molecular backbone of polyamide PA12 contains a large number of polar amide groups, which makes the polyamide molecules have a strong force. , And can form hydrogen bonds (generally the greater the hydrogen bond density, the better the mechanical strength, the more the number of carbon atoms, the worse the strength), and at the same time make the molecules of polyamide PA12 neatly arranged, with crystallinity; polyamide PA12 molecular main The chain segment also contains *, which makes the polyamide flexible and can affect the melting point and glass transition temperature (Tg) of polyamide PA12; in addition, the main chain end of the polyamide macromolecule contains amino and carboxyl groups. The reactivity is easily modified. Compared with other materials, these polyamide PA12 with amide group (-CONH-) structure have a series of excellent properties. Polyamide PA12 resin is a material with excellent comprehensive properties, but it also has obvious shortcomings, such as temperature sensitivity, water absorption greatly affects dimensional stability, and poor low-temperature toughness. Modification through chemical or physical methods can greatly improve its performance. For example, by adding glass fiber materials, the water absorption and dimensional stability can be greatly improved, and the strength and toughness of the resin can be improved; various alloys can be made by blending with other polymers to replace metals, Traditional materials such as wood.
Polyamide 12 elastomer (nylon 12 elastomer) is a thermoplastic elastomer (TPE) material. It is a block polymer, including PA12 segment and polyether segment (polyether block amide). Products rich in PA12 have the main properties of PA12, and the properties of elastomers become more obvious with the increase of polyether content: that is, the polymer becomes softer and has higher low-temperature impact strength. Due to its excellent properties, this polymer is indispensable in many applications.
