Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of thermal conductive silicone, it is recommended to prioritize confirming key technical parameters such as thermal conductivity and temperature resistance range to ensure compatibility with scenarios such as electronic device heat dissipation or LED packaging.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. For example, suppliers who have been serving new energy vehicle battery modules for a long time may be more reliable.
  • In different scenarios such as industrial power supplies or consumer electronics, the viscosity and insulation performance of thermal conductive silicone need to be adjusted according to specific applications, and high-density packaging usually requires products with lower viscosity.
  • If the procurement involves a large number of orders, it is recommended to evaluate the stability of the supplier's production capacity and delivery cycle based on their industry performance and platform statistical information, in order to avoid the impact of supply chain fluctuations on production progress.
