Thermally Purified Carbon Additive (TPC18) for Low Iron / Ultra Clear Glass
Low Iron / Ultra Clear Glass delivers maximum clarity and color neutrality clear to the edge, without the green tint of a standard float glass. Low Iron offers more light transmission vs regular soda-lime glass. Low Iron glass is widely used in applications in which low coloration and/or high optical transmission is desired.
Ultra-low Iron content retains clarity even when manufactured in heavier thicknesses, unlike conventional clear glass, which becomes progressively greener and darker as thickness increases.

Take Control of Color Using TPC18, a Thermally Purified Carbon Additive
Superior Graphite has recently developed TPC18, a Thermally Purified Carbon product specifically for Low Iron or Ultra Clear Glass application, virtually free of color imparting heavy elements like Iron (Fe <75 ppm). The high-temperature purification treatment of the carbon allows for the highest purity, low gas content, and superior consistency. TPC18 has a very specific morphology and pore structure, coming from Superior Graphite’s proprietary high-temperature treatment, greatly enhancing the dissolution speed of carbon in the melt.
TPC18 Main Features:
- Ultra-High Purity Carbon (>99.7%)
- Exceptionally low level of impurities, Fe (<75 ppm ), Cr (<10 ppm), Cu (<10 ppm)
- Highly consistent product quality
- Guaranteed low gas content, O2, N2, and H2
- Extremely low Sulfur content (<0.03%)
- High speed dissolution due to very high surface area and porosity
- Made in the USA
