Purchasing Guide

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

  • For the purchase demand of sealant strip, it is recommended to give priority to check the technical parameters such as temperature resistance range (-40 ℃ to 120 ℃), anti-aging performance and compression deformation rate, which directly affect the sealing effect and service life of doors, windows or curtain walls.
  • Sealing strips in automotive manufacturing need to pay attention to oil resistance and rebound rate, while in the construction field, more emphasis is placed on UV resistance performance. When purchasing, suitable specifications should be selected according to specific scenarios.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information. For example, suppliers who have been serving in the rail transit field for a long time may be more familiar with sealing requirements in high-frequency vibration environments.
  • Sealing strips for industrial equipment need to consider medium compatibility (such as acid-base environment). It is recommended to conduct a comprehensive evaluation based on the measured data provided by the supplier and industry application cases.
