With its good elasticity and softness, processability, wear resistance, cold resistance, heat resistance and other characteristics, TPE materials can meet the needs of a variety of application scenarios, so they are widely used in various fields. However, in the process of using TPE materials, there are times when TPE materials cannot be melted due to various reasons. So do you know what causes TPE materials to not melt? Here's what you know:
Reasons why TPE materials cannot be melted:
1. Formula problem:
The elastomer composition of the TPE material may not be sufficient to melt. At this time, it is necessary to readjust the formulation of the TPE material, increase the content of the elastomer component, and improve its melt flow index.
2. Quality problems:
There may be quality problems in the TPE material itself, such as raw material quality problems, production process problems, etc. At this time, the TPE material needs to be rigorously tested and evaluated to ensure its quality and reliability.
3. Impurities:
The TPE material contains too many impurities or chemicals that may cause it to fail to melt. At this time, strict quality control of raw materials is required to avoid impurities and chemicals entering the TPE material.
4. Processing technology problems:
The TPE material may not be processed properly, resulting in its failure to melt. For example, the processing temperature is too low, the processing time is insufficient, or the processing pressure is too high. In this case, it is necessary to adjust the processing process to increase the processing temperature, extend the processing time, and increase the processing pressure.
To sum up, it is the reason why TPE materials cannot be melted, but in general, the failure to melt TPE materials is caused by the combined action of a variety of factors, therefore, in order to minimize the occurrence of the phenomenon that TPE materials cannot be melted, it is necessary to consider various factors in the process of production, processing and use, and take corresponding measures.
