Purchasing Guide

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

  • For procurement requirements that require the use of plastic alloys, it is recommended to prioritize confirming key technical parameters such as temperature resistance range, impact strength, and flame retardant rating of the materials. These indicators directly affect their applicability in scenarios such as electronic casings or automotive components.
  • 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 and material performance consistency.
  • In different application scenarios such as industrial gears or medical devices, it is necessary to select product specifications that meet the actual working conditions based on the differences in wear resistance and biocompatibility of plastic alloys.
  • When purchasing plastic alloys, it is recommended to evaluate the melt flow rate (MFR) parameters based on injection molding process requirements, while also paying attention to the actual project case data of suppliers in the field of chemical new materials.
