Pressboard is a type of durable cardboard, perfect as an electrically insulating material in electrical devices.
Properties
Pressboard is a special type of durable cardboard. It is created by wet felting plant fibers, followed by layering, pressing, and smoothing. It is made of noble fibrous raw materials, hard pulp, and waste paper.
It has the following properties:
-
dielectric resistance and resistance to electric breakdown - electrotechnical pressboard
-
resistance to short-term thermal loads up to 350°C
-
high mechanical resistance to abrasion and bending
-
flexible and very smooth surface
-
low density - 1.10 - 1.25 g / cm3
-
ease of cutting, pressing, crushing, and partially forming
The most common color of pressboard is beige, in sheets of various thicknesses and sizes.
Application
Pressboard is most often used as an insulator in low voltage motors, transformers and various types of electrical apparatus. In addition, it has such applications as:
-
the electrical insulating material in the tailoring industry
-
finishing fabrics in the textile industry
-
notebook covers, office supplies, boxes, etc., in bookbinding
-
water and oil seals and coil frames
