It is made up of 80 to 85% recycled newsprint, and the remaining 15% consists of borax, boric acid or ammonium sulfate, which helps make the newsprint fibers more fire-resistant—and can help to repel insects!

What is insulation resistance?

An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective the dielectric (insulation) is in resisting the flow of electrical current.
