Key Guidelines

1.  Machining & Installation Points:

       Cutting: Recommend using carbide-tipped saw blades at high speed to avoid tearing.

       Bonding: Use PVC-specific adhesive or polyurethane structural adhesive to ensure bond strength.

       Thermoforming: Heat evenly to 120-140℃ until pliable, then form; avoid localized overheating and scorching.

2.  Selection & Design Advice:

       Outdoor Use: Must select products with UV-resistant formulations, or apply weather-resistant surface treatments (laminating/coating).

       Load-Bearing Requirements: Select board with sufficient density and thickness based on mechanical calculations, or design reinforcing rib structures.

       Cleanroom Environments: Choose low-VOC, anti-static formulations suitable for partitions in electronics workshops or medical spaces.

Proven Applications

   National Chain Brands: Uniform indoor/outdoor signage systems (wind-resistant, weather-resistant, lightweight installation).

   High-Speed Rail/EMU Interiors: Wall panels and ceiling panels (meeting EN45545 HL3 flame retardancy, 30% weight reduction).

   Prefabricated Bathroom/Kitchen Units: Cabinet bodies and panels (fully waterproof, zero formaldehyde, factory prefabricated).
