POLYTON PT.Sharp is a dry toner powder formulated for refilling laser printer cartridges in Sharp-compatible devices, produced by a specialised Russian toner manufacturer. Its published physical parameters are the ones refilling professionals actually check: controlled particle size distribution (coarse fraction above 150 µm strictly limited), a defined melt flow index around 18–20 g/10 min for predictable fusing behaviour, specified tribo-charge characteristics, and a black saturation of 58 units for dense, uniform print.
These properties together determine whether a refilled cartridge prints cleanly or scatters background — which is why cartridge refillers buy toner by specification, not by colour. Compatible toner is the economic backbone of the print services industry: refilling cuts per-page cost several-fold against OEM cartridges.
The product is supplied wholesale from 500 units at about 3 USD each, terms aimed at cartridge refilling businesses, managed print service providers and office supplies distributors serving corporate fleets of Sharp-platform printers and MFPs.
