Fiberglass (Fibreglass) is an inorganic non-metallic material with excellent performance. There are many types. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, the disadvantage is that it is brittle and has relatively high wear resistance. difference. It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is how many A micrometer to more than twenty micrometers, equivalent to 1/20-1/5 of a hair strand, each fiber strand is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was initially compiled for reference. Special-purpose fibers, such as E glass and "475" glass fiber, are in the 2B carcinogen list, and continuous glass fibers are in the list of 2B carcinogens. In the list of 3 types of carcinogens.
