Purchasing Guide

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

  • For procurement requirements that require the use of COC, it is recommended to prioritize confirming key technical parameters such as the melt index and glass transition temperature of the material, which directly affect the applicability of injection molding processes.
  • COC is widely used in the fields of medical packaging and optical devices. When purchasing, the performance differences of materials such as light transmittance and chemical resistance should be evaluated according to specific scenario requirements.
  • When selecting COC suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistics, with a particular focus on application case data in the medical or electronics industries.
  • Different batches of COC may have performance fluctuations. It is recommended to request suppliers to provide recent testing reports and compare stability with historical data before procurement.
  • If used in precision scenarios such as high-frequency communication devices, special attention should be paid to whether the dielectric constant and loss factor parameters of COC meet industry standards.
