What Glue Is Used in Construction Plywood?

In international construction projects, construction plywood is generally divided into two main types: Film Faced Plywood and Phenolic Plywood.

While surface film and core veneers are important, the glue used in plywood production plays a decisive role in overall strength, durability, and water resistance. At Sunmmax, glue quality is never compromised. Our glue formula is jointly developed in collaboration with leading Chinese universities, using premium-grade raw materials rather than low-cost substitutes.

Premium Raw Materials We Use

Melamine: Supplied by Jinxiang Chemical (Sichuan) — China’s largest and most reputable melamine producer

Flour Filler: Food-grade flour from Wudeli and Jinshahe, two of China’s top flour brands widely recognized for consistent quality

These materials are all top-tier brands within their respective industries, ensuring stable chemical performance and reliable bonding.Only glue that meets our strict standard is approved for production:Minimum required viscosity: ≥ 180

Glue directly determines:

Bonding strength between veneers

Resistance to water and moisture

Reuse times in concrete formwork

Long-term structural stability

Low-quality glue often leads to delamination, reduced reuse times, and higher replacement costs on site. By advanced formulation, premium raw materials, and strict daily testing, Sunmmax has ensured its film faced plywood and phenolic plywood consistently meet the demands of international construction projects worldwide.
