Purchasing Guide

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

  • For procurement requirements that require the use of general grade engineering plastics, it is recommended to prioritize confirming key technical parameters such as temperature resistance, mechanical strength, and chemical corrosion resistance of the materials to ensure compliance with specific application scenarios such as automotive components or electronic casings.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. Such suppliers are usually able to consistently provide general-purpose engineering plastics that meet industrial standards.
  • In the field of industrial equipment or consumer goods manufacturing, there are significant differences in the requirements for the flowability (melt index) and dimensional stability of general-purpose engineering plastics in different application scenarios. Therefore, it is necessary to clarify the processing conditions before procurement.
  • If the procurement volume is large, the stability of the supplier's production capacity can be evaluated based on their industry data support capabilities, while paying attention to their actual case performance in injection molding, extrusion and other processing fields in the past.
