Flake-form pipe stabilizers for sewage, pressure-pipe, and cable-canal formulations.
These pipe grades are presented in flake form and targeted at sewage pipe, high-pressure pipe, and cable-canal production. The grade table details lead content, bulk density, moisture, and dosage bands for the three variants.
Two recommended formula tables are included for different extrusion setups, showing how carbonate loading, stabilizer dosage, waxes, and additives shift between sewage and pressure-pipe recipes.
