ETP STP Chemicals

Product Description

The offered ETP STP Chemicals have a high molecular weight, cationic dry flocculent that are used to improve fiber and ash retention in papermaking. The product has a synergistic effect in combination with other additives like coagulants and fixation aids. The powder is dissolved in water to a 0.3 -0.5 % stock solution, which is diluted to about a tenth of its original concentration before dosage to the paper machine. ETP STP Chemicals are normally added just before the head box to achieve maximum efficiency, dosing is recommended after the pressure screens, where the flocks are submitted to a minimum of shearing force.
