Import Core Board Paper — Buy in Bulk from Supplier in China

Core board paper F400 is a high-density specialty paper engineered for industrial use, offering strong mechanical properties and electrical insulation. The grade designation F400 indicates a dense composition suited for structural and protective applications, with thickness and dimensional stability meeting standard industry tolerances for core board materials.

The material is typically produced from virgin kraft pulp, with a smooth, uniform surface and low moisture content to ensure stability in humid environments. Standard industry grades like F400 are often used in layers for added rigidity, with a typical basis weight range of 200 to 600 GSM depending on the application. The paper’s resistance to compression and bending makes it a reliable choice for packaging, electrical insulation, and construction.

This product is sourced by manufacturers in electronics, packaging, and construction sectors where durability and consistency are critical. It is often used as a core material for honeycomb boards, protective edge boards, or as a layer in composite panels. Buyers should confirm the exact GSM, thickness tolerance, and moisture content for their specific use case, as these parameters directly impact performance in high-stress applications.
