Low-density chipboard (extruded tubular particleboard) functions as an engineered wood core panel designed to reduce overall assembly weight without compromising structural rigidity or acoustic insulation.
Manufactured through continuous vertical extrusion, the internal parallel air channels decrease panel weight by up to 40% compared to solid particleboards. This configuration ensures uniform thickness and high compression resistance across the flat surfaces, making it a reliable semi-finished core material for door and furniture manufacturers.
Key Features
Extruded Tubular Structure: Internal parallel air channels distribute weight evenly, reducing overall door or panel mass while retaining perpendicular load resistance.
Dimensional Stability: Balanced cross-section minimizes moisture-induced warping, critical for oversized interior doors and architectural panels.
Acoustic & Thermal Insulation: Enclosed air chambers provide baseline sound transmission class (STC) ratings and thermal break properties.
Machine-Friendly Surface: Calibrated faces accept standard wood veneers, high-pressure laminates (HPL), and edge banding without telegraphing core patterns.

Applications
Architectural & Interior Doors: Functions as the structural core for flush wooden doors, fire doors, and sound-insulated room doors.
Office Furniture & Partitions: Applied in heavy-duty desk tops, conference tables, and mobile workstation screens to reduce dead weight for hardware longevity.
Lightweight Cabinetry: Used in frameless cabinet construction and thick shelving units prone to sagging under traditional solid core weights.
Customization Options
Dimensions: Custom lengths and widths cut on automated sizing saws to minimize post-purchase yield loss.
Edge Profiling: Pre-drilled tubular channels for electrical wiring integration or customized edge sealing.
Density Tuning: Adjustable extrusion pressure to tweak core density based on specific screw-holding or weight requirements.
Fire-Retardant Impregnation: Additive-treated wood chips for projects requiring strict commercial building codes.

Production Assets: Equipped with automated German Waldrich extrusion lines and multi-opening hot presses, ensuring uniform resin distribution and precise thickness calibration.
In-House Laboratory: Daily batch testing for internal bond strength, moisture content (controlled at 6-10%), and formaldehyde chamber tests.
Certifications: FSC-COC Chain of Custody, CARB P2, and ISO 9001 quality management system compliance.
Logistics: Secure horizontal strapping, edge protectors, and moisture-barrier shrink wrapping optimized for 40-foot container (HC) maritime transport.
FAQ
Q: Can standard hinges and hardware hold securely in low-density chipboard?
A: Yes. While the core features tubular voids, the solid edge bands and face layers provide adequate screw-holding capacity. For heavy hardware installations, specify reinforced solid wood framing or insert dowels during door fabrication.
Q: How does this material perform in high-humidity environments?
A: Standard grades are rated for interior climate-controlled environments (IPSC 1 / EN 315 Service Class 1). For semi-exterior or high-moisture spaces, moisture-resistant (MR) resin formulations are available upon request.
Q: What is the minimum order quantity (MOQ) for custom thicknesses?
A: Standard thicknesses (33 mm, 38 mm) run in continuous production cycles. Custom thickness setups require a minimum order of one 20ft container (20FCL) to account for tooling adjustments.
