The quality of phenolic faced plywood is better than that of melamine faced plywood.
Phenolic faced plywood can be turned over more than 15 times, melamine faced plywood can be turned over more than 10 times.
The water resistance of phenolic faced plywood is better than that of melamine faced plywood, and the price of is more expensive.
The phenolic glue is boiled in boiling water for 24 hours without opening, and the melamine glue is boiled in boiling water for 5 hours without opening.
Phenolic faced plywood, the material is strict, the core material is the drier the better, the production cycle is long, are two hot pressing forming.
What is the difference between phenolic glue and melamine glue? The fundamental difference is actually the amount of phenol content, phenolic glue phenol content is higher than melamine glue.
The price of phenolic faced plywood is higher than that of melamine faced plywood. The number of times the film faced plywood is used mainly depends on the glue, pressure and the quality of the inner core board.
Phenolic glue due to its good waterproof performance, coupled with the quality of the whole core board , if it is put into the water at the same time as construction plywood, it will be found that the phenolic faced plywood will not be delaminated for one night, and the melamine glue will be delaminated after cooking for about 12 hours.
Phenolic resin has a large number of benzene rings in the glue, and can be cross-linked to form a shape structure, large rigidity, so high heat resistance, good dimensional stability.
