Products classified under HTS 4804.31.10.00
Electrical Grade Kraft Condenser Paper 28 g/m² Rolls
Unbleached kraft paper in rolls weighing 28 g/m², engineered for capacitor winding with superior tear resistance and insulation properties. Fits HTS 4804.31.10.00 as uncoated, unbleached condenser paper in the specified weight band, distinct from sack or liner grades. Sulfate process ensures >80% wood fibers for consistent electrical performance.
Dielectric Kraft Condenser Tissue 22 g/m²
22 g/m² unbleached kraft tissue serving as dielectric in power factor correction capacitors, in large rolls for automated winding. Precisely matches HTS 4804.31.10.00 for unbleached condenser paper weight specs and uncoated kraft makeup. High tensile strength in machine direction suits high-speed manufacturing.
Unbleached Kraft Condenser Tissue Paper 25 g/m²
This unbleached kraft paper, weighing 25 g/m², is specifically designed as condenser tissue for use in electrical capacitors to provide dielectric insulation between conductive layers. It meets the criteria for HTS 4804.31.10.00 as unbleached kraft paperboard in rolls or sheets, weighing over 15 but not over 30 g/m², and qualifies as condenser paper due to its high purity and density for electrical applications. The chemical sulfate process fibers ensure minimal impurities for reliable performance in high-voltage environments.
Kraft Condenser Separator Paper 20 g/m²
High-purity unbleached kraft separator paper at 20 g/m² used in electrolytic capacitors to separate electrodes while allowing ionic conduction. Classified under HTS 4804.31.10.00 for its unbleached kraft composition, low weight range, and role as specialty condenser paper in roll form. The paper's uniform fiber structure from sulfate pulping ensures low electrical conductivity and high breakdown voltage.
Capacitor Grade Unbleached Kraft Paper 18 g/m²
Specialty 18 g/m² unbleached kraft paper for metallized film capacitors, providing thin dielectric layers in high-frequency applications. HTS 4804.31.10.00 applies due to its condenser-specific properties, unbleached sulfate fibers, and precise weight in sheets or rolls. Optimized for minimal thickness variation essential in precision electronics.
