Products Description
Transformer insulation pressboards, also known as bakeboard and phenolic laminated board, uses high-quality bleached wood paper and cotton lint paper as reinforcements, and is made of phenolic resin reacted with high-purity, fully synthetic petrochemical raw materials. Wooden boards made of resin adhesive.
Due to their properties of insulation, no static electricity, wear resistance, and high-temperature resistance, bakelite boards have become insulating switches and variable resistors for electronic products, molds for machinery and fixtures on production lines, and can be used in transformer oil and other products.
