As shown in the figure on the left, the standard colors are Lexan 143R-111 clear PC (transparent white tint) and Lexan 143R-701 PC (opaque black). Cylindrical granules. Please contact us if you require custom colors.👉+86 15837933829

Sabic 143R-111 PC Advantage

  • UV resistant PC, Compared to the PC resin in Lexan 141R of the same series, Lexan 143R-111 PC contains UV stabilizers that enable it to achieve a UL 746C F1 rating for UV light and water exposure/immersion. This effectively slows down yellowing and performance degradation, thereby extending the service life of PC products.
  • Good processability. The melt flow rate (MFR) of Lexan 143R PC resin at 300°C and 1.2 kg is 10.5 g/10 min. It can be processed using standard injection molding equipment, and the material also contains a mold release agent to reduce material residue in the mold.
