The main component of these substances, ceramics, cement, and quartz, is SiO2. In addition, SiO2 is also used to make optical fibers.Elemental silicon is used to make solar panels, chips and other materialss
PVC board is a kind of vacuum plastic film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications. According to the degree of soft and hard can be divided into soft PVC and hard PVC. According to the production process can be divided into PVC crust foam board and PVC free foaming board.s
Alkali free borosilicate glass has the characteristics of high surface smoothness, low coefficient of expansion, high temperature resistance, no alkali precipitation and good insulation. Without potassium and nano plasma, it is an important glass raw material for the electronics and Optoelectronics industries. In addition, they do not contain arsenic, antimony, barium, and halides.s

FR4 is the pure epoxy board of NEMA standard. The normal color should be dark green. This is the color of epoxy. There are also yellow, generally called yellow FR4 called yellow material, white (green) called white material.FR4 is more expensive than epoxy board and fiberglass board cannot confirm the price.s
This is because of containing nickel sulfide crystal glass raw material, manufacturing technology in the world is any existing can not be completely avoided, only reduce the exploding probability through control of the purity of raw materials and processing technology to a.s
