Hollow Core Particle Board is a tubular particleboard with a density of 0.35-0.55 g/cm³, making it 60% lighter than flat-pressed door core board. It offers 28dB sound insulation, 2MPa compressive strength, and thermal insulation equivalent to a 300mm brick wall. Its thickness-wise water absorption and expansion are minimal.
Tubular chipboard, also known as tubular core particleboard or hollow core particle board, retains the essential characteristics of wood while overcoming its inherent shortcomings, such as shrinkage and swelling. It is considered a new generation of green and environmentally friendly door core material and is widely used in the cores of various wooden doors.
Tubular Core Particleboard, also known as Bridge Hole Mechanical Board, is a door core board produced using an extrusion process. Its name stems from its tubular structure, which resembles a bridge hole. Tubular Core Particleboard disperses external forces through its hollow tubular structure. Its applications include wooden door cores, partitions, and furniture manufacturing.
