LUVITEC® gets new packaging
New packaging protects high molecular weight powder from oxidation
Now a new plastic film gives even better protection to Luvitec® high molecular weight powders from penetrating oxygen from the air. Luvitec® (polyvinylpyrrolidone, abbreviation: PVP) is an important component in the manufacture of specialty membranes and specialty adhesives. “With the new packaging, we can guarantee our customers even better and, in particular, consistent product quality. The membrane industry in particular is dependent on consistent product properties and purity,” explains Dr. Markus Lohscheidt, Global Business Management PVP at BASF.
The new film offers reliability
The new packaging made of ethylene vinyl alcohol plastics (abbreviation: EVOH) gives the high molecular weight PVP powders reliable protection from oxidation. The EVOH film has optimum sealing properties. It also has excellent chemical resistance, very good tensile strength, and is impermeable to gases and fluids. Thus, all the relevant product properties remain protected, not just now but for years to come. BASF guarantees a shelf life of up to three years for high molecular weight powders.
Highest product quality for sensitive membranes
Specialty membranes made of plastic materials are essential where gentle methods are required to clean or keep materials separate, in other words without using heat or chemicals. Ultrafiltration membranes, for example, keep drinking water free of bacteria and viruses. And they are used in dialysis to wash toxins out of human blood. By using Luvitec, thousands and thousands of tiny pores and channels are created in the membrane. They are essential for the separation process.
