Composites Systems Business

Composites is a Global Business: 

Composites is a Global Business Key facts: $1 Billion in Revenue Number 1 in Global Market Share 20 Production Sites - 750,000 Tons of Composites Increasing demand for Global Consistency

Definition of Glass: 

Definition of Glass ASTM: An inorganic product of fusion which has cooled to a rigid condition without crystallizing. General: Glass is a liquid which can be cooled without crystallizing and is so viscous at room temperature that for all practical purposes it is a solid. Glass is amorphous, i.e., it does not have an ordered atomic structure.

Advantex® Glass Fiber is a Reinvention of E-Glass: 

Advantex® Glass Fiber is a Reinvention of E-Glass “E-glass” was developed in 1937 by OC and OSU The goal was to develop a glass with excellent electrical insulation properties (E) water durability tensile strength E-glass is primarily CaO, SiO2 and Al2O3 E-glass contains alkali level less than 2%

Boron Was Added to Lower Liquidus and Viscosity: 

Boron Was Added to Lower Liquidus and Viscosity Most E-glass formulations are variations of the original composition

Slide10: 

The Role of Boron in E-Glass Melting

Typical Glass Composition: 

Typical Glass Composition E-Glass Container/ Flat Glass SiO2 54 73 CaO 22 6 MgO --- 5 Al2O3 14 1 B2O3 8 --- Na2O 0.5 15

Driving Forces for Change: 

Driving Forces for Change Extended Performance Increasingly complex product design demands for physical, mechanical, chemical & electrical criteria Global Consistency Manufacturers need to source materials with uniform properties around the globe Environmental Stewardship Increasing demand for materials to be produced in environmentally responsible processes

Slide13: 

Glass Melting Based Upon Fossil Fuel Consumption Batch Furnace Forehearth Forming Channel Raw Materials Emissions from Melting Process

Major Emissions to the Air:: 

Major Emissions to the Air: CO2 combustion of hydrocarbon fuels decomposition of carbonate batch material SOx sulfate from salt cake or gypsum sulfur in fuel NOx high temperature required to produce glass efficiency and oxidizing atmosphere Particulate volatile components of the glass condense in the stack primarily boron compounds

Increased Performance with Advantex® : 

Increased Performance with Advantex® Properties of E-glass with higher corrosion resistance Higher softening point improves service life or temperature Providing New Solutions or Applications Automotive exhaust systems Compact and Lighter Lower System Cost Improve Corrosion Properties Eliminate Particulate Blow-out Meet Tighter Noise Requirements

Conclusions: 

Conclusions Introduction of Advantex® glass fiber marks an important milestone for Owens Corning Advantex® glass fiber is one of many solutions Owens Corning is providing to create new value for our customers Owens Corning’s consumption of silica and dolomite will increase Owens Corning will need new sources of the mineral dolomite

Conclusions (continued): 

Conclusions (continued) Advantex® will help meet customer demands for Global consistency Advantex® has electrical and mechanical properties of boron containing E-glass Advantex® glass fiber provides higher temperature applications and corrosion resistance compared to boron containing E-glass

Conclusions (continued): 

Conclusions (continued) Advantex® will have a significant impact upon reducing amount of particulate emissions with elimination of added boron and fluorine Advantex® helps enable conversion to oxygen combustion and therefore obtain reductions in NOx emissions

Global Composites Materials Use Transportation Infrastructure Consumer Electrical / Electronics Construction

Slide32: 

In 1992 Owens Corning Fiberglas produced just under $3 billion in sales, and glass fibers made up over 80% of its material base. Expertise Beyond Fiberglass... By 1998 Owens Corning became a multi-material based company with sales over $5 billion and glass fibers constituting less than 50% of its material base.
