Why phenolic plywood i

Date:Oct-19-2014 Read:4210 Times 【 Fonts:161412 Source:http://www.sjzlzw.cn/english/newswood/newswood/520.html

Phenolic plywood is about 10 -18% more expensive than MR and melamine plywood of same thickness . Customers usually ask why phenolic plywood is so expensive . The reasons are as the following:

1. Phenolic glue is 50-80% more expensive than MR and melamine glue .

2. In order to guarantee a better glue bonding strength, the compression time for phenolic plywood have to be longer than that for MR/melamine plywood . This means we have to spend more producing time for phenolic plywood than MR/melamine plywood . Spending more time means costs increase .

 

 

3. Because the compression time for phenolic plywood is longer, the compression ratio for phenolic plywood is bigger than that for MR/melamine plywood . This leads to that the veneers for phenolic plywood must be thicker than the veneers for MR/melamine plywood of same thickness . In this situation, the costs of core veneers for phenolic plywood are higher than that for MR/melamine plywood .

4. Because the compression time for phenolic plywood is longer, the energy (including coal,electricity and so on) will be spent more and the labor costs will rising accordingly during the production of each piece of phenolic plywood .

Because of the above mentioned 4 reasons , the phenolic plywood is much more expensive than MR/melamine plywood .

However, do you prefer phenolic plywood or MR/melamine plywood ?
