After the dot honeycomb panel is processed, residual internal stress can be eliminated through post-processing techniques such as heat treatment or vibration aging.
PP composite board (polypropylene composite sheet) has become an important material in the automotive manufacturing industry due to its excellent physical properties, lightweight characteristics, and high degree of customization.
With breakthroughs in materials science, thermoplastic vulcanized TPV sheets are gradually replacing traditional EPDM rubber and PVC, becoming the preferred material for automotive sealing components.
The replacement of PHC paper honeycomb panels with extruded fiberglass board as the new favorite for spare tire covers is a result of advancements in automotive material technology and evolving user needs.
A dot honeycomb panel is an innovative lightweight composite material, formed by hot-pressing or adhesive bonding of two panels and a honeycomb core layer with a regular dot matrix distribution in the middle.
PP Composite Board, with its unique material properties, controllable mechanical properties, and excellent processing adaptability, becomes an ideal choice for such energy-absorbing and cushioning components.
