Purchasing Guide

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

  • When selecting the expansion series, it is recommended to prioritize checking the product specifications such as expansion coefficient, temperature resistance range, and pressure bearing capacity. These indicators directly affect its applicability in scenarios such as building joints or pipeline sealing.
  • The expansion series is widely used in chemical equipment protection and underground engineering waterproofing scenarios. Before procurement, it is necessary to clarify the specific requirements of the use environment for material corrosion resistance and expansion rate.
  • Supplier selection can refer to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information to ensure that their technical solutions match project requirements.
  • For the procurement of expansion series under high temperature conditions, it is necessary to pay extra attention to the thermal stability test data provided by the supplier and compare the lateral parameters with similar products.
