Fiberglass is a kind of inorganic non -metallic material with excellent performance. There are many types. The advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is crispy, abrasion resistance is more abrasion -resistant Difference. It is made of leaf stone, quartz sand, limestone, white clouds, boron calcium stones, and boron stone as the raw materials. The micron to more than twenty microns is equivalent to 1/20-1/5 of a hair wire. Each fiber fiber is composed of hundreds or even thousands of single silk. Glass fiber is usually used as enhanced materials in composite materials, electrical insulation materials and thermal insulation materials, and circuit substrates and other national economies.
On October 27, 2017, the list of carcinogens published by the International Cancer Research Agency of the World Health Organization was initially organized. Special use fiber, such as E glass and "475" glass fiber 3 Class 3 carcinogens list.
