Difference between bakelite board and epoxy board, do you know?
Bakelite and epoxy boards are both commonly used sheets in industry and have a wide range of applications. Let's take a closer look at the characteristics of these two types of boards and the application scenarios.
Bakelite: a representative of insulation and durability
Bakelite board is a synthetic cardboard that belongs to plastic products. Its professional name is Bakelite Phenolic Laminated Paperboard, which is mainly made of phenolic resins reacting with high-purity, fully synthetic petrochemical raw materials. Bakelite board is insulating, non-absorbent, non-static, abrasion-resistant, and high-temperature-resistant, so it is commonly used in insulated switches, variable resistors, molds, and fixtures on production lines for electronic products. It can also be used in transformer oil, good electrical properties at room temperature, specific gravity of about 1.45, warping less than 3 ‰, with good electrical and processing properties. Paper glued wood is a common form of bakelite board, widely used in a variety of industrial laminates, especially suitable for use in motors and electrical equipment with high mechanical performance requirements.
Epoxy boards: the choice for high insulation and heat resistance
Epoxy board is also known as epoxy fiberglass board or epoxy phenolic laminated glass cloth board. It is made of fiberglass cloth bonded with epoxy resin and made by heating and pressing. Epoxy board has high mechanical properties under medium temperature and stable electrical properties under high humidity. It is suitable for high insulating structural parts for machinery, electrical appliances and electronics, with high mechanical and dielectric properties, good heat and moisture resistance. The heat resistance grade is F (155 degrees). Specification thickness ranging from 0.5 ~ 100mm, heat deformation at high temperatures of 180 degrees Celsius, generally not with other metals in a piece of heat, so as not to cause deformation of the metal plate. Epoxy plate (FR-4) has high mechanical properties and dielectric properties, good heat and moisture resistance, and good machinability.
Summarize
Bakelite and epoxy boards each have their own characteristics. Bakelite boards are known for their insulation and durability, while epoxy boards are known for their high insulating and heat-resistant properties. Choosing the right board according to the specific application requirements can better utilize their advantages.
