Lead-free Glass Material

 

Find Suppliers by Category

Glass materials have a random, liquid-like (non-crystalline) molecular structure. They are excellent thermal insulators and electrical insulators, and have high dielectric strength. At ordinary temperatures, glass materials are relatively strong, inert, biologically inactive, and corrosion resistant.
