18mm Darkbrown Film Faced Plywood
Excellent waterproof performance: Brands DADIWISA and DADIVISA use WBP waterproof glue, with a water absorption rate as low as ≤10%, making it resistant to outdoor humid environments.
Brand names: DADIWISA and DADIVISA.
The 18mm darkbrown film faced plywood is a specialized construction material designed for high-load scenarios, featuring a precise 18mm thickness and darkbrown phenolic film. Produced by Langfang Dadi Wood Co., Ltd.-established in 2002 with a 300,000-square-meter factory-this 18mm darkbrown film faced plywood uses high-quality core materials and phenolic resin binder, ensuring exceptional stability and durability. The 18mm darkbrown film faced plywood can withstand repeated use up to 25-30 cycles, with no warping or cracking, making it suitable for shear walls, bridges, and large-scale concrete pouring. Backed by 500+ professional technicians, it meets the strict requirements of national key projects like Beijing Daxing Airport.
