Purchasing Guide

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

  • For procurement requirements that require the use of silicone sealing strips, it is recommended to prioritize confirming key technical parameters such as hardness, tensile strength, and temperature resistance range of the product to ensure its suitability for sealing requirements in different scenarios such as doors, windows, automobiles, or industrial equipment.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable supply solutions for silicone sealing strips.
  • Silicone sealing strips used in high temperature or humid environments require additional attention to their aging resistance and compression set rate to avoid sealing failure due to environmental factors.
  • For special scenarios such as building curtain walls or food grade equipment, it is recommended to choose silicone sealing strips with smooth surfaces that meet environmental standards, and to evaluate them comprehensively based on the supplier's industry performance data.
