## New OSU Compliant Polycarbonate Developed

- Polycarbonate-like physicals & Processability
- Improved chemical resistance
- Available in opaques (including white)
- Polycarbonate-like optical properties
- Hard coating possible
- Synthesis validated in commercial facility
- Robust performance in:
-  OSU
-  NBS Smoke

## Opaque LEXAN* FST9705 Commercialization Progress

- On Track for Commercialization 2nd Qtr 07

- * Trademarks of General Electric Company

## Transparent Commercialization Progress 

- Technology Ready For Manufacturing Validation

## FAR and Customer Tox. Properties1

- 1. - Typical properties at third-party lab, as might be seen on a data sheet
- 2. - Representative of multiple colors and lots
- 3. - Lab sample
- 4. – Injection molded, non-hard coated

## Sample OSU Graph

## Sample Smoke Density Graph

## Transparent Resins: Physical Properties

**Similar to “60 Sec Vertical” PC in Aircraft**

## Transparent Resins: Optical  Properties 

-  - Transmission up to 86% (tint dependent) should    be possible
-  - Variety of tints possible – up to opaques
-  - Haze < 2%

- Developmental Values  - May Change With Commercialization
