- Complies with UL 94 V-0 standard down to 1.0 mm and UL 94 5VA standard at 3.0 mm
- Products that comply with UL F1 are available
- Excellent anti-draping properties
- Provides a non-brominated, non-chlorinated, nonphosphate, non-Teflon† solution
- Improved flow and processability compared to standard clear FR polycarbonate
- Specific grades for injection molding or extrusion
- Improved flow and processability
LEXAN CFR resins offer improved flow and processability compared to standard clear, FR polycarbonate. Due to the effects of shear thinning, a LEXAN CFR resin grade with a melt flow index (MFI) of 18 can have a spiral flow (indicative of practical flow in injection molding) similar to that of an FR polycarbonate with an MFI of 28. Similarly, a LEXAN CFR resin grade with an MFI of 5 has a spiral flow equivalent to that of an FR polycarbonate with an MFI of 14.

- ʰ Measurements made from laboratory test coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
- ᵖ UL ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. For details, please see the UL Yellow Card.
- ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
