The plywood core is the most important element for film-faced plywood quality. YALONGFORM features core types including recycled core, poplar core and eucalyptus core (Poplar veneers are sourced in Northern China. Eucalyptus veneers are source from Southern China or Vietnam). All these materials are sourced legally from local suppliers in China. YALONGFORM ECO is made from used formwork panels so it is an eco-product with a cheap price. Read more about core types.

Glue Types

Glue used for plywood are UF, Melamine UF, Phenolic UF. Urea Formaldehyde is rarely used for formwork plywood due to its low resistance to moisture and rain.

Read more about glue types.

WBP Melamine

Melamine fortified urea-formaldehyde glue is a very strong adhesive with waterproof capability. Film faced plywood made with melamine glue can withstand 10-24 hours of water boiling without delamination. It’s an economic WBP glue compared with phenolic. WBP melamine is also called B-bond.

WBP Phenolic

Phenolic is the best glue for formwork plywood. It is a permanent WBP bond that can bond the veneers permanently without delamination forever. Phenolic is also called A-bond for its great performance. It can withstand a 48-72 hours boil test.

Film Types

Yalong branding film or custom printed black/brown/red color smooth film. The film is opaque and impregnated with phenolic glue. Square or hexagon patterned anti-slip film also available. The film are usually generic brand or dynea brand.

Waterproof Edge Seal

It is important to seal the edges of the film faced plywood. Formwork plywood is used outdoor and in direct contact with concrete so it must be waterproof. Rain and concrete will inevitably invade the glue line of plywood unless the plywood is sealed on the edges.

Before the edges are painted, we fill them with putties and phenolic glue. Waterproof paint is sprayed to make sure the formply edges are perfectly sealed. When you cut the plywood at the job site, make sure that you seal the cut edges before you use them.

Is phenolic overlaid plywood waterproof?

The phenolic film overlay is super smooth and waterproof. The four edges of the panel sheet is also sealed in order to obtain a waterproof capability. The glue inside the plywood is WBP weather and boiling proof bond. It is not 100% waterproof but the treatment can prevent the plywood to swell under humid.

Due to its durability film faced plywood is widely used in concrete forming and vehicle flooring, loading platforms, truck and trailer floors and wagons.

Is phenolic film faced plywood structural?

Phenolic bonded plywood is used for load-bearing but it is not necessarily structural. Non-structural plywood can also be used in the formwork. If you need specially structural plywood please indicate to our sales team.
