Owens Corning is the leading global supplier of gla ss reinforcements to the composites industry

• 1939: OCV invented E-glass– Boron added to glass for electrical properties

• 1968: OCV developed S-2 Glass ®

– High Performance Glass (high melting power needed)– Small capacity furnaces due to limits in melting technologies

• 1980: OCV developed ECR Glass ®

– Corrosion resistant glass.

• 1997: OCV developed Advantex ® Glass and Technology

Innovations in Glass Melting Technologies

4

– Boron free E-glass (higher melting power than traditional E-Gl ass)– ECR-glass (Superior corrosion resistance to traditi onal E-glass)– Breakthrough in melting technology for large capaci ty furnaces

• 2006: OCV developed High Performance Glass (HPG) Technology

– Combines High-Performance Glass and Melting Technol ogy– Production of High-Performance Glass in large capac ity furnaces

• 2008: OCV developed new S-glass formulation based o n HPG technology

– Boron-free glass formulation that meets all interna tional standards for S-glass• ASTM C-162, DIN 1259, ISO 2078, ASTM D578, and JIS R3410 standards.

– Resulting in -> Lower Cost, Increased Capacity, Hig her Fiber Homogeneity
