"Peers rely on trial and error, glpoly uses theoretical calculations" Whenever we introduce thermally conductive silicone materials to customers, we define our brand in this way. Our target markets are front-line high-end applications such as automotive, 5G communications, industrial control medical, and intelligent systems, so materials focus on functional testing, product stability, and durability.
In recent years, the supply resources of many customers have gradually shifted from imports to local procurement, which is an opportunity to promote the development of domestic thermal conductive silicone manufacturers. However, only a few of them can come out on top, and glpoly is one of them. Most of the peers have not crossed the threshold set by customers, the reason is that the product reliability is not good, or the hardware level of the production line is insufficient, and more may be insufficient test equipment and so on.
Thermal calculation formula
Glpoly has R&D capabilities to support customers in thermal design, material applications and other aspects of the questions encountered. One of the key points is the "heat balance" relationship of heat dissipation demand. Take an example of a "wireless charging" use case for cars.
We can calculate the value by the heat transfer coefficient k and the thermal conductivity λ, substituted into the formula δ. When the customer does not exceed the numerical value when designing the gap thickness δ the required heat balance can be achieved. Assuming that the heat source heat q1 is known, the temperature of the heat source and the aluminum plate t, the heat source area a, the thermal conductivity λ, the simplified formula δ =k/λ
Under the above conditions, we can get the following reference information: "The thermal conductivity of 2.0w/m·k is sufficient for this design." “
In addition, we discuss with our customers the relationship between balancing temperature and heat. As shown in the following figure, when q1 < q2, the relationship between equilibrium temperature and heat is linear

Knowing the details of the component drawings and the application environment, in order to calculate the accurate mathematical simulation, our derivation, in advance to give the customer engineer a heat transfer idea.
Choose glpoly, the same quality assurance as imported brands, more meticulous professional answers than big brands.
