Purchasing Guide

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

  • For procurement requirements that require the use of PI, it is recommended to prioritize confirming key technical parameters such as temperature resistance range and dielectric constant of the product to ensure compatibility with the existing production environment.
  • In application scenarios such as industrial automation or high-frequency circuits, the thickness uniformity and thermal stability of PI may directly affect the performance of the final product.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • There may be performance differences between different batches of PI, and it is recommended to verify the stability and consistency of supplier products through small-scale trials.
