Product introduction

Product description of Bakelite Phenolic Board
Bakelite Phenolic Board is made of cotton cloth impregnated with phenolic resin, baked and hot pressed. The heat resistance rating is E. With high mechanical properties, oil resistance and dielectric properties, phenolic cloth boards have high mechanical strength, excellent moisture resistance and heat resistance, good electrical properties (poor board), and are easy to process. Phenolic cloth boards are widely used in electrical products. Phenolic laminated paper and cloth board have a density of about 1.5g / ㎝, which is lighter than aluminum and is used in aerospace and other structures.

Bakelite Fabric Board Product Features

Bakelite fabric board has good chemical resistance, can resist organic solvents, organic acids and dilute inorganic acids. It is suitable for many chemical equipment and generally not suitable for alkaline media.
Bakelite boards can withstand sawing, drilling, turning, milling, planing and other processing. No cracks and slags should appear after processing. The thickness can be punched below 3㎜. The cold punching type does not require heating. General models need to be preheated After punching. They are used for insulating parts of high and low voltage electrical appliances and electronics industries.
Phenolic cloth board has better processing performance than paperboard and glass cloth board, higher adhesive strength and impact strength than paperboard, but has higher water absorption, reduced electrical insulation after moisture absorption, and easy to grow enzymes. It is not suitable for use in hot and humid areas. Therefore, it is generally used as the insulating structural parts of low-voltage motors and appliances, such as gaskets, slot wedges, and screws. There are many types of glass cloth panels, and their performance varies with different binder resins. Compared with other laminates, glass cloth panels have higher mechanical strength and heat resistance. Under high temperature, their resistance to bending and resistance Although the tensile strength and tensile strength have been reduced, they are still higher than those of paperboard and cloth board.

Textolite Phenolic Board Product Usage

Textolite phenolic board is widely used in mechanical, electrical and electronic fields. It can be used as insulating structural parts in generators, motors, distribution cabinets and other electrical equipment that requires certain mechanical and electrical properties. Can be used in transformer oil. Can also be used as a wear-resistant, oil-resistant gasket for motors. The heat resistance grade is E grade. Appearance: The surface is smooth and smooth, without wrinkles and cracks. Try to avoid other defects, such as abrasions and indentations, with a small amount of stains. Products: There are mainly NEMA LE and NEMA CE models. NEMA LE grades can be used to make gears, trunnions, terminal strips, and various stamped parts. NEMA CE grade can be used for bearing housings / housings, motor / generator slot wedges, wear-resistant washers, gears and trunnions, etc.
