C4B Insulation Board Product Data 

Madera laminada de alta densidad

Material Details

Grade: C4B. (Type: Wood Based Laminates)

Description: Wood Veneer. Superior Wood Laminate.

Comments: It is formed from fine birch, which is cut into veneers and dried, and then glued and laminated by hot pressing.  It has the advantages of moderate density, high mechanical strength, easy vacuum drying, and easy machining.  Its dielectric constant is close to that of transformer oil, and its insulation is reasonable.
