Purchasing Guide

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

  • For procurement requirements that require the use of PU, it is recommended to prioritize confirming key technical parameters such as material hardness and rebound coefficient, which directly affect the performance of the product in industrial buffering or sealing scenarios.
  • In the fields of automotive interior and furniture manufacturing, the application of PU needs to pay attention to its differences in weather resistance and wear resistance, and there are clear distinctions in the adaptation scenarios of products with different thicknesses and densities.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply chain stability.
  • When purchasing PU, it is necessary to consider the consistency requirements of the production batch. Some electronic device packaging scenarios have high standards for material purity and anti-static properties.
