The amount of silica aluminum oxide and magnesium oxide in S- glass has significantly more than E glass, it is stronger 40-70% than E glass.. Manufacturers are constantly adjusted S glass formulations.The different glass type in composite materialsPosted by zccyfiberglass on December 22nd, 2015alkali-free or E glass, it’s named by its chemical composition, which is an excellent electrical insulator, which is particularly suitable for application to the desired radio signal, better transparency areas, such as aircraft radomes, antennas and printed circuit board. At the same time, it is also the most economical glass fiber composite materials to meet at a relatively low cost in many applications, which will provide enough performance requirements strength. At least 50% of E- glass fiber is made of silica oxide;fiberglass chopped strand mat the rest consisting of aluminum, boron, calcium and / or other compounds, also include limestone, fluorite, boric oxide and clay.

When the temperature is up to 540&Spring love song Roller Coating Aluminium Sheets Factory 8451;, the strength of E glass and S glass will lose a half. It has become the standard form of glass fiber, accounting for more than 90% glass fiber reinforced materials.When you need more strength, high-strength glass become an option, it was first developed in the 1960s and used for military applications. The new S-3 UHM (ultra-high modulus) glass, for example, AGY (Aiken, SC, USA) launched a tensile modulus of the new S-3 glass has 14,359 in 2012 - higher than the S- glass and 40% higher than # E glass - due to improved manufacturing and proprietary additives and melt chemistry of the fiber. Although this two types of fibers in this elevated temperature range still showed unusual strength
