What are the benefits of nylon 66?

Nylon 66 is a kind of high performance engineering plastic, with excellent physical and chemical properties, widely used in automotive, electronics, aerospace, medical equipment and other fields. The way to identify nylon 66 is as follows:

1. Observe the appearance: The appearance of nylon 66 shows the characteristics of good gloss, hard texture and smooth surface.

2. Feel: Nylon 66 feels hard and has certain elasticity, but it will not be as soft as rubber.

3. Thermal stability: Nylon 66 has good thermal stability and can maintain stability at high temperatures.

4. Wear resistance: Nylon 66 wear resistance is better, can maintain good performance in the case of friction, wear and so on.

5. Chemical properties: Nylon 66 has good tolerance to acid, alkali, oil and other chemicals, and is not easy to be corroded.

6. Melting point: the melting point of nylon 66 is relatively large, generally above 250℃.

Through the above several aspects of judgment, nylon 66 can be more accurately identified. This article will introduce the benefits of nylon 66, process and precautions.

First, the benefits of nylon 66

High strength: Nylon 66 has good tensile strength and bending strength, and can withstand large loads and shocks.

Heat resistance: Nylon 66 has good heat resistance and can run for a long time in a high temperature environment.

Corrosion resistance: Nylon 66 has good corrosion resistance, can resist acid, alkali, oil and other chemical substances erosion.

Wear resistance: Nylon 66 has good wear resistance and can run for a long time under friction and wear environment.

Good processing performance: Nylon 66 has good processing performance and can be processed by injection molding, extrusion, blow molding and other processes.

Second, nylon 66 process

Injection molding process: It can be processed by injection molding process, it should be noted that the melting point of nylon 66 is large, and it needs to be heated to a larger temperature to melt.

Extrusion process: It can be processed by extrusion process, it should be noted that the melting point of nylon 66 is large, and it needs to be heated to a larger temperature to melt.

Blow molding process: It can be processed by blow molding process, it should be noted that the melting point of nylon 66 is large, and it needs to be heated to a larger temperature to melt.

Precautions for nylon 66

Heating temperature: Its melting point is large, and it needs to be heated to a higher temperature to melt, but too high a temperature will lead to the decomposition and deterioration of nylon 66, affecting its performance.

Mold design: Its shrinkage rate is large, which needs to be taken into account in mold design to avoid product deformation and size inaccuracies.

Processing pressure: Its melting point is large, and it requires a large processing pressure to process, but too much pressure will lead to product deformation and surface is not smooth.

Processing speed: Its melting point is large, and it needs a faster processing speed to avoid excessive heating and decomposition, but too fast a speed will lead to the product surface is not smooth and the size is not accurate.

Storage conditions: Nylon 66 needs to be stored in a dry environment to avoid moisture absorption and deterioration, affecting its performance.

In short, nylon 66 is a high-performance engineering plastic, with excellent physical and chemical properties, widely used in automotive, electronics, aerospace, medical equipment and other fields. When processing nylon 66, it is necessary to pay attention to the heating temperature, mold design, processing pressure, processing speed and storage conditions to ensure the quality and performance of the product.
