Purchasing Guide

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

  • For procurement requirements that require the use of insulation materials, it is recommended to prioritize checking key technical parameters such as voltage rating and dielectric constant to ensure compatibility with the operating conditions of power equipment or electronic components, such as significant differences in material performance requirements between high-voltage substations and low-voltage circuits.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support, especially in fields such as new energy or rail transit that require high reliability of insulation materials.
  • Different application scenarios such as cable sheaths, motor windings, or PCB substrates require differentiation of material types. The temperature resistance and mechanical strength of different materials such as silicone rubber and epoxy resin directly affect their service life.
  • When purchasing insulation materials in the industrial sector, it is recommended to evaluate the stability of the supplier's products based on their industry data support. For example, in precision scenarios such as aerospace or medical equipment, batch consistency of materials is particularly critical.
