Phenolic Cotton Cloth Laminate referred to as phenolic cotton cloth board in line with JB/T8149.2-2000,Q/JBQP21-2001
Phenolic cotton laminate is made of cotton cloth impregnated with phenolic resin by drying and hot pressing, 3136 is made of bleached cloth impregnated with phenolic resin by hot pressing and laminates. 3025 has high mechanical properties, suitable for machinery, motors, electrical equipment for insulating structural parts, and can be used in transformer oil. 3136 has high mechanical strength, suitable for use as adhesive tape gear wheel, guide wheels and other machinery products. Parts
Phenolic Cotton Cloth Board is a material made of cotton cloth impregnated with phenolic resin, dried and hot-pressed. Specifically, phenolic cotton cloth is made by immersing cotton cloth in heated and melted phenolic resin, and then dried and hot-pressed.
Characteristics
Phenolic cotton cloth board has the following properties:
Heat resistance: phenolic resin has excellent heat resistance and can remain stable in high temperature environments
Chemical stability: able to resist the erosion of a variety of chemical substances, with good chemical stability
Fire performance: phenolic cotton cloth board has good fire performance, commonly used in the production of various industrial parts
Flatness: the surface should be flat, no bubbles allowed
Application field
Phenolic cotton cloth boards are often used for various industrial parts because of their excellent performance under normal conditions.
What is Bakelite?
A.Bakelite :
Bakelite(sometimes spelledBaekelite) is a combination of phenol, formaldehyde, and wood flour. The mixture is put under pressure, and after curing, a hard plastic material forms.
Bakelite 3021:also called Paper-based phenolic laminated sheet,is consists of impregnated paper dipped in resin by baking and hot pressing.3021 is the most commonly sen laminates,as well as having the widest applications and largest usage.
Bakelite 3025:also called Phenolic cotton cloth laminated sheet is consists of cotton cloth dipped in phenolic resin by baking hot pressing.3025 is manufactured by modified phenolic resin as binder and pure cotton fabric as reinforcement.They have exceptionally good heat resistance and will not creep under high temperature conditions.
B.Bakelite Sheet / rod features
Excellent physical,mechanical and dielectric properties
Withstand all kinds of machining
Surface smooth, no bubbles, hemp eye and impurities
Edges cutting tidiness, Surface without delamination and crack
C.Bakelite Sheet / rod applications
In insulating structural parts
Electric equipments
Aeronautical industries
