Can thermal silicone sheets be recycled? How long is the shelf life? How should it be stored?

The topic of product recycling and reuse is a hot topic in any industry, and there has been a lot of chatter about the topic of recycling. Some advocate recycling, and some advocate not recycling and discarding directly. But then again, can thermally conductive silicone sheets be recycled? Moreover, the country is also deeply promoting the topic of garbage classification, so can the thermally conductive silicone sheet be classified and recycled? The following is a detailed and in-depth explanation and analysis of the thermally conductive silicone sheet material of our CoolThermo.

We can start from the relevant properties of the raw materials of the thermally conductive silicone sheet, and deeply discuss the recyclability and availability of the thermally conductive silicone sheet material. At present, the raw materials of general thermally conductive silicone sheets are nothing more than divided into materials with high thermal conductivity and medium and low thermal conductivity. Materials with high thermal conductivity generally include polymer nitrides, carbides, etc. Metal oxides (alumina, oxidase, etc.) generally have medium and low thermal conductivity. The thermal conductivity of thermally conductive silicone sheet material directly affects and determines the overall performance of the material and its function and role.

Secondly, from the processing technology of the raw material of the thermally conductive silicone sheet, the raw material of the thermally conductive silicone sheet needs to be vulcanized at a high temperature of 150 ° C, and the process of converting from liquid to solid. At this time, a very important part of the thermally conductive silicone sheet has been completed – molding, which simply means the appearance of the thermally conductive silicone sheet. Therefore, if there is material loss or defective products in the future, due to irreversible changes in the material itself, the material cannot be effectively recycled.

From the perspective of customers, the performance of the thermally conductive silicone sheet will undergo some slight changes after several years of use, but it will not affect the main performance indicators of the thermally conductive silicone sheet. For example, the thickness and hardness of the thermally conductive silicone sheet will vary greatly, so the thermally conductive silicone sheet is not recyclable. Although the thermally conductive silicone sheet is not recyclable, the material itself of CoolThermo thermally conductive silicone sheet is environmentally friendly and pollution-free. Please use it with confidence.

Through CoolThermo’s specific and in-depth explanation and analysis of the thermally conductive silicone sheet material, we understand that the thermally conductive silicone sheet cannot be recycled. Therefore, users will pay more attention to the use, life, storage period and storage conditions of the thermally conductive silicone sheet.

We know that thermally conductive material products have a certain shelf life and a certain storage time. It’s just that the length of time is different. As a professional thermal conductive silicone sheet manufacturer, Nuofeng NFION will attach great importance to the product’s life, storage time and storage conditions. Many customers worry that the product’s shelf life is very short. It will affect the use of their products, so as to cause problems such as short order delivery time and short delivery cycle for materials.

The shelf life of thermally conductive silicone sheets is related to many factors. Among them, the most important is the raw material and molecular composition of the thermal conductive silicone sheet. The shelf life and durability of the raw material directly determine the shelf life of the finished thermal conductive silicone sheet. Generally speaking, the shelf life of thermally conductive silicone sheets can be kept for at least 6 months. Of course, the shelf life of the finished thermal conductive silicone sheet corresponding to materials with higher thermal conductivity will be longer, and the currently known shelf life can reach 18 months.​​

In addition, this is the data tested under normal temperature conditions. The higher the storage temperature, the shorter the shelf life of the thermally conductive silicone sheet, the less conducive to the preservation and storage of the thermally conductive silicone sheet. Once the material is applied to the product, the life of the product will be greatly increased. The reliability life of the product can reach more than 6 to 8 years, which guarantees the service life of the product to the greatest extent. Therefore, the shelf life of the thermally conductive silicone sheet will be affected by the material itself and the external temperature.

What should be paid attention to in the storage conditions of thermally conductive silicone sheets?

  1. First of all, be sure to avoid sun exposure;
  2. Store the thermally conductive silicone sheet in a dry and cool place;
  3. The storage temperature should be 15-30 degrees Celsius, do not store at high temperature;
  4. The humidity of the storage environment should be less than 75% as much as possible.
