Phenolic paper laminates
Phenolic paper laminates
3021 bakelite sheet/board
This product is also called bakelite board, phenolic laminated paperboard, using high-quality bleached wood pulp paper and cotton linter paper as reinforcements, and phenolic resin (phenolic resin made by the reaction of high-purity, fully synthetic petrochemical raw materials) as the reinforcement. Adhesive manufacturing, baked, hot-pressed phenolic laminated paperboard, which has the characteristics of insulation, no static electricity, wear resistance and high temperature resistance. It has become an insulating switch and variable resistor for electronic products, and a motor with high mechanical performance requirements. , Electrical equipment neutralizes insulating structural parts, and can be used in transformer oil transformation. It is also used in PCB industry drilling pads, distribution boxes, mold splints, high and low voltage wiring boxes, tea trays, etc., color: orange Red, black, yellow, brown
