Polyvinyl acetate PVAC for Gumbase . PVAC for gumbase is divided into Low, Middle and Higher Melocular Weight. Normally, it's in form of granules.
Polyvinyl Acetate (PVAC) is the main ingredients of gumbase as Flexible & Chewing elements. It improves the filmig effect and mouth feeling. PVAC based gumbase can produce larger & thinner bubbles. It's less sticky in summer and of long validity. According to the market tastes, each manufacturer adds a certain percentage of PVAC into gumbase. It becomes the blow-able and un-eatable part in gumbase.
