Purchasing Guide

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

  • In the actual procurement process of molded polystyrene boards, it is recommended to prioritize checking key technical parameters such as density, thermal conductivity, and compressive strength to ensure compliance with specific scenario requirements such as building exterior wall insulation or cold storage insulation.
  • When selecting suppliers, priority can be given to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to screen suppliers that meet long-term cooperation conditions.
  • For different application scenarios such as roof insulation or underfloor heating installation, attention should be paid to the thickness specifications and fire rating differences of molded polystyrene boards to avoid affecting the engineering effect due to parameter mismatch.
  • Molded polystyrene board is prone to performance fluctuations in low-temperature environments. When purchasing, suppliers can be requested to provide measured data under relevant climatic conditions as a basis for selection.
