Highly flexible Redispersible polymer powder

Special-Function Type Redispersible polymer powder


Redispersible polymer powder is a free-flowing white powder formed by spray-drying EVA emulsion. It readily re-emulsifies and disperses in water to form a stable emulsion. In addition to possessing the superior properties of the original EVA emulsion, its free-flowing powder form offers exceptional convenience and reliability during handling and storage.
