Thermoplastic polyimide is a new generation of high-performance special engineering plastics. It not only retains the traditional thermosetting polyimide's high strength, high temperature resistance, chemical resistance, good dielectric properties, radiation resistance and other characteristics, but also improves the processability, in addition to the use of hot molding method, it can also be used Extrusion or injection molding.

Main characteristics of thermoplastic polyimide

1. Outstanding machinability characteristics: injection molding, extrusion, hot molding, and spray molding; no small molecules are released during processing, the shrinkage rate is small, and the dimensional accuracy of the parts is high

2. Excellent comprehensive mechanical properties: high modulus, impact resistance, creep resistance, is an ideal structural functional material

3. High heat distortion temperature, good heat resistance, and good mechanical strength in a wide range of high and low temperatures

4. High insulation and excellent dielectric properties

5. Stable chemical properties, resistant to all kinds of grease, organic solvents; flame retardant, anti-aging

6. Abrasion resistance, an excellent anti-friction and anti-friction matrix material

7. Pure materials: no small molecule substances that pollute the environment during processing and use.

Thermoplastic polyimide applications

Thermoplastic polyimide can be widely used in aerospace, automotive, electronic appliances, precision machinery and other fields due to its excellent comprehensive performance. It can be made into precision parts such as plates, rods or pipes, films and structural composites, such as gears, bearings, connectors, etc. It is an ideal material for replacing metals, ceramics, low-temperature or difficult-to-process thermosetting resins in specific occasions.

At present, the advanced polymer materials with the highest temperature resistance grade on the market are thermosetting polyimides represented by VESPEL of DUPONT. However, due to the difficulty of processing and molding, the product form is mainly finished or semi-finished products, and the application is narrow. expensive. Secondly, thermoplastic polyimide (TPI) represented by MURUI's AURUM, and polyetheretherketone (PEEK) of VICTREX. Such materials can be formed by extrusion, injection and hot compression molding, which greatly improves the processability.

NGDJ—thermoplastic polyimide is the same type and grade of polymer material as AURUM of MITSUI Company, all performances reach AURUM resin index, and the molding temperature is much lower than AURUM resin; compared with PEEK and other special engineering plastics ( Such as PES, PPS) have obvious advantages in mechanical properties, thermal properties and friction and wear performance.

Our company specializes in the production of polymer composite materials such as PTFE PPS PEEK PI PEI and other wear-resistant and high-temperature self-lubricating materials.

热塑性聚酰亚胺

热塑性聚酰亚胺，是新一代的高性能特种工程塑料。它不仅保留了传统热固性聚酰亚胺的高强度、耐高温、耐化学腐蚀、介电性能好、抗辐射等特性，而且提高了可加工性，除可采用热模压成型方法外，也可采用挤出或注射方法成型。

热塑性聚酰亚胺主要特性

1. 突出的可加工特性：可注塑、挤出、热模压、喷涂成型；加工时无小分子放出，收缩率小，制件尺寸精度高

2. 综合力学性能优异：高模量，耐冲击，抗蠕变，是一种理想的结构功能材料

3. 热变形温度高，耐热性好，在较宽的高低温范围内具有良好的力学强度

4. 绝缘性高，介电性能优异

5. 化学性质稳定，耐各类油脂、有机溶剂；阻燃、抗老化

6. 耐磨损，为一种出色的减摩、增磨基体材料

7．材料纯净：加工和使用过程中无对环境污染小分子物质放出。

热塑性聚酰亚胺应用领域

热塑性聚酰亚胺以其优异的综合性能，可广泛应用于航空航天、汽车、电子电器、精密机械等领域。它可制成板材、棒材或管材、薄膜及结构复合的精密部件，如齿轮、轴承、接插件等，在特定场合下为替代金属、陶瓷、低温或难加工热固性树脂的理想材料。

目前，市场上耐温等级*高的先进聚合物材料是以DUPONT公司的VESPEL为代表的热固性聚酰亚胺，但由于其加工成型困难，产品形式主要以成品或半成品为主，应用面窄，价格昂贵。其次是以MITSUI公司的AURUM为代表的热塑性聚酰亚胺（TPI），以及VICTREX的聚醚醚酮（PEEK）。此类材料可采用挤出、注射和热模压成型的方法成型，大大改善了可加工性能。

NGDJ—热塑性聚酰亚胺与MITSUI公司AURUM属同一类型和级别聚合物材料，各方面性能均达到AURUM树脂指标，而且与AURUM树脂相比成型温度低得多；与PEEK及其它类特种工程塑料（如PES、PPS）相比在力学性能、热性能及摩擦磨损性能方面均有着明显优势。
