Premium Block Board for Sturdy & Aesthetic Woodwork - SiliconPly

Silicon Block Board

SILICON Block boards are manufactured from the combination of selected, seasoned, durable Pinewood timber battens, veneers and adhesives. These are bonded with Urea Formaldehyde Resin under high pressure and temperature for MR grade and Phenol Formaldehyde resin for BWP grade. The block boards are resistant to twisting/warping, has superb screw holding & nail holding capability. Thus, SILICON BOARD makes the work easy. This is mainly possible because of seasoned & durable timber which is used. The wooden battens are thoroughly seasoned in scientifically run seasoning kiln plants and then cut with great precision to obtain uniform thickness.
