  1. Our PP plastic honeycomb is a lightweight, high\u2011stiffness core material made from polypropylene and formed into a stable hexagonal cell structure. Compared with solid plastic sheets and plywood, it offers an excellent strength\u2011to\u2011weight ratio, impact resistance, low water absorption and good chemical resistance. Laminated with fiberglass, aluminum or decorative skins, it becomes a durable sandwich panel widely used in truck and van bodies, caravan floors, ship and boat decks, packaging pallets and industrial enclosures.<\/li>\n

    Polypropylene honeycomb is corrosion\u2011free, moisture\u2011proof and easy to process by cutting, CNC machining, thermoforming and bonding. It maintains dimensional stability in humid and marine environments and provides good vibration damping and noise reduction when combined with suitable facings. We offer multiple cell sizes, densities, thicknesses and panel dimensions, allowing you to customize PP honeycomb solutions for automotive, marine, construction and interior applications on your independent website.<\/p>\n

    \uc720\ud615<\/td>\nPP plastic honeycomb core \/ honeycomb sandwich panels \/ blocks; supplied as core-only or bonded with skins (fiberglass, aluminum, steel, decorative laminates, FRP, etc.) for lightweight structural, impact\u2011resistant, and corrosion\u2011free applications.<\/td>\n<\/tr>\n
    Structure<\/td>\nRegular hexagonal or thermo\u2011welded cell structure made from polypropylene sheets\/film, heat\u2011bonded to form an ultra\u2011lightweight, high\u2011stiffness honeycomb core with good energy absorption and vibration damping.<\/td>\n<\/tr>\n
    PP Grade<\/td>\nTypically high\u2011quality polypropylene (PP) with good chemical resistance and low water absorption; UV\u2011stabilized or flame\u2011retardant grades available on request according to outdoor, marine, or building requirements.<\/td>\n<\/tr>\n
    Cell Size<\/td>\nTypical cell size from about 4 mm to 12 mm (or customized); smaller cells provide higher compressive and shear strength and better surface flatness, while larger cells reduce weight and material cost and can improve acoustic and thermal performance in sandwich panels.<\/td>\n<\/tr>\n
    Cell Shape<\/td>\nStandard hexagonal or \u201ctubular\u201d cell configuration as default; special geometries and slit\u2011oriented cores available to meet specific stiffness, forming, or weight\u2011saving requirements.<\/td>\n<\/tr>\n
    Film \/ Web Thickness<\/td>\nPP film\/web thickness typically from about 0.2 mm to 0.8 mm, selected according to required density, compressive strength, shear strength, and weight; higher thickness\/density grades used for heavy\u2011duty or high\u2011load applications such as truck floors and industrial platforms.<\/td>\n<\/tr>\n
    Overall Thickness Range<\/td>\nCore thickness typically from about 5 mm to 100 mm or more; finished sandwich panel thickness depends on core height and facing skins, commonly in the range of 10\u201360 mm for transportation, marine, building, and industrial panels.<\/td>\n<\/tr>\n
    Panel Size (L \u00d7 W)<\/td>\nCore blocks and panels available from small cut pieces to large\u2011format panels (e.g., up to approx. 1220 \u00d7 2440 mm or larger, depending on production line and transport conditions); special sizes, shapes, and pre\u2011cut components available on request.<\/td>\n<\/tr>\n
    Density Range<\/td>\nDensity adjustable via cell size and web thickness; typical densities from approx. 60 kg\/m\u00b3 to 160 kg\/m\u00b3, offering very low weight with tailored stiffness, compression strength, and impact performance.<\/td>\n<\/tr>\n
    Mechanical Properties<\/td>\nHigh stiffness\u2011to\u2011weight and strength\u2011to\u2011weight ratio; good in\u2011plane and out\u2011of\u2011plane shear properties; excellent impact resistance and energy absorption; widely used as a load\u2011bearing or stiffening core in sandwich panels where low weight and corrosion\u2011free performance are required.<\/td>\n<\/tr>\n
    Thermal & Acoustic<\/td>\nLow thermal conductivity for basic insulation and thermal comfort; honeycomb structure contributes to vibration damping and noise reduction when combined with suitable facings and optional acoustic layers; commonly used in vehicle bodies, cabins, and building interiors.<\/td>\n<\/tr>\n
    Moisture & Corrosion<\/td>\nPolypropylene honeycomb is inherently corrosion\u2011free and moisture\u2011resistant; it does not rot, rust, or delaminate in humid or marine environments, making it ideal for boat decks, truck bodies, and outdoor constructions.<\/td>\n<\/tr>\n
    Surface Finish (Core)<\/td>\nCore typically supplied in natural or colored PP with as\u2011formed cell surfaces; edges can be cut, CNC\u2011machined, or sealed (edge\u2011potted or capped) to suit bonding, cleanliness, and environmental protection requirements.<\/td>\n<\/tr>\n
    Surface Finish (Panels)<\/td>\nWith skins: compatible with fiberglass, carbon fiber, aluminum sheets, steel, HPL, PVC, and decorative laminates; external surfaces can be finished with gelcoat, paint, films, anti\u2011slip textures, or decorative layers according to aesthetic and functional requirements.<\/td>\n<\/tr>\n
    Bonding & Adhesives<\/td>\nCores bonded to skins using suitable adhesive systems for PP and the chosen facing (e.g., PUR hot\u2011melt, PP\u2011compatible adhesives, epoxy with surface treatment, etc.); heat\u2011lamination and vacuum press processes commonly used for panel production.<\/td>\n<\/tr>\n
    Temperature Performance<\/td>\nDesigned primarily for ambient to moderate service temperatures typical of automotive, marine, and building applications; specific heat\u2011stabilized or flame\u2011retardant grades available where higher temperature or fire\u2011performance requirements apply.<\/td>\n<\/tr>\n
    Chemical Resistance<\/td>\nGood resistance to many acids, alkalis, salts, and common cleaning agents; suitable for use in wet, dirty, or chemically aggressive environments where traditional wood\u2011based cores would degrade.<\/td>\n<\/tr>\n
    Processing & Forming<\/td>\nCore can be cut, sawn, CNC\u2011machined, water\u2011jet cut, and thermoformed for gentle curvature; panels can be routed, folded, drilled, and mechanically fastened according to design; suitable for bonding inserts, profiles, and edge\u2011closures for assembly.<\/td>\n<\/tr>\n
    Dimensional Tolerances<\/td>\nControlled cell size, density, core thickness, and flatness; specific tolerances for core and finished panels can be supplied according to project specifications or applicable industrial\/building standards (e.g., thickness, bow, twist, and dimensional accuracy).<\/td>\n<\/tr>\n
    Standards & Reference<\/td>\nManufactured with reference to relevant plastics, sandwich panel, and building\/transport standards (e.g., EN, ASTM) covering mechanical performance, dimensional control, and where applicable, fire behavior and emission requirements.<\/td>\n<\/tr>\n
    Application Range<\/td>\nTruck and trailer bodies, caravan and motorhome floors, ship and boat decks, yacht interiors, clean\u2011room and cold\u2011room panels, building fa\u00e7ades and partitions, exhibition stands, sport and leisure equipment, and other lightweight, corrosion\u2011free structural components.<\/td>\n<\/tr>\n
    Customization<\/td>\nCustom cell size, density, core thickness, block size, machining, and contouring; compatible with a wide range of skin materials (fiberglass, aluminum, steel, decorative laminates, etc.); supplied according to drawings, CAD models, or specific project requirements.<\/td>\n<\/tr>\n
    Form of Supply<\/td>\nSupplied as raw PP honeycomb core blocks, cut\u2011to\u2011size sheets, machined or pre\u2011shaped cores, or fully assembled sandwich panels ready for installation or further fabrication; optional edge\u2011close\u2011out, inserts, and profiles available.<\/td>\n<\/tr>\n
    Packaging<\/td>\nCores and panels packed with edge protection and moisture\u2011resistant wrapping; suitable separators, cartons, or wooden pallets used to maintain flatness and prevent mechanical damage or contamination during transport and storage; special packaging available for export or high\u2011value projects.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/li>\n<\/ol>\n
