Gusmer is a major distributor of Divergan F to the beer industry. Manufactured by BASF, Divergan F is used throughout the world to chill haze stabilize beer. BASF’s unique polymerization process produces the purist polyvinylpolypyrrolidone, which selectively adsorbs the polyphenols that can cause instabilities. There is evidence that Divergan F also helps to stabilize flavor through the reduction of flavonoid polyphenols, which are particularly prone to polymerize into products of higher molecular weight and potential bitter flavor. Divergan F works quickly, and its short contact time means it can frequently be dosed inline, but it can also be dosed in a batch method.
Divergan RS is a regenerable PVPP, which works in the same manner, but offers some economies to larger facilities that are set up to regenerate it.Divergan F Sizes: 20 kg drums
Divergan RS Size: 20 kg drums
Particle Size: ~ 50 um

Preparation of Stabilizers
The amorphous powder should be mixed with deoxygenated water at a 10% w/w ratio. (1 kg powder: 10 liters DAW or ~8 lb: 10 USG DAW). The use of a CO2 sparger in the slurry water will help to deoxygenate the water. Agitate slurry for 1-2 hours prior to addition.
