Introduction to the
Yulong board as the substrate, composite wood, technology wood, PVC, etc. The CNC center for cutting, slotting, and then UV roll coating production line from。
Performance advantage
Class B fireproof, with heat insulation, cold, waterproof, moistureproof, moth-proof, impact resistance, high wear-resisting degree, long service life, no anti-halogen, zero formaldehyde, simple construction.
