Defoamer for PVA is a kind of high efficient defoamer with modified polysiloxane material. 
With the good thermostability and chemical stability, this defoamer can produce stable unbalance surface tension in foams, to completely remove all big and tiny foams. Thus it can control well the foams problem during the whole production, largely improving the product quality.  

(1) Fast defoaming ability, lasting foam suppressing effect, small dosage, not any effect to the basic property of foaming system.

(2) Good heat resistance, good chemical stability, non-corrosive, non-toxic, non-flammable, non-explosive, no adverse side affect.

(3) Comparable with top quality product on market, while the price is much more affordable. 

Defoamer for PVA is used in polyvinyl alcohol emulsion(EVA), styrene-acrylic emulsion, styrene-butadiene latex, emulsion polymerization, PVC resin production, synthetic rubber degassing, wet method PU synthetic leather resin defoaming, etc. 

                                            

Apply to synthetic rubber                                                                          Apply to synthetic latex 

Usage: Direct add this defoamer into the foaming system. It also can be used together with other powdered additives after mixing evenly.  

Recommended dosage: 0.1~1% of total formula, but the optimal dosage should be determined through actual testing.
