The Brabender planetary mixer P 600 is used for testing the properties of powders like e.g. the liquid sorption and the drying time of PVC powders in compliance with international standards:
• DIN EN ISO 4612 Preparation of a paste from PVC paste resins
• DIN 54802 Determination of plasticizer sorption and rate of plasticizer sorption in the heat of vinyl chloride (VC) polymers
• ASTM D 2396 Standard test methods for powder-mix time of poly(vinyl chloride) (PVC) resins using a torque rheometer
Furthermore, it is applied for analyzing the pourability of PVC dry blends, further for preparing PVC pastes for tests and testing them in compliance with DIN EN ISO 4612. A special rotor runs in a planetary motion in the mixer bowl. A revolving scraper prevents the sample material from sticking to the mixer wall.
