polyvinyl acetate (pvac) is largely used in FRP industry for SMC/BMC products. the polyvinyl acetate (pvac) is to promot the performance in anti shrink, glossness, and stree of the final products, like head lights etc.
this pvac granule is for industrial usage. The PVAC Granule is also called polyvinyl acetate granule. It can be divided into higher, middle and lower molecular. higher molecular PVAC Granule is normally used for Glass Fiber Reinforced Plastics (GFR), like in Light Cover for automobiles; Lower molecular PVAC Granule is used in Cement concret to form a more stable floor deck for buildings.
