Product Description

Polyvinyl Acetate Beads

Backed by a modern manufacturing plant, we are a renowned manufacturer, exporter and supplier of Polyvinyl Acetate Beads. This products is composed of vinac resins, which are small, glass like beads of high purity polyvinyl, which is used in laminating label & hot melt adhesives, overprint varnishes, pigmented & grease proof paper coating, industrial lacquers & coating printing inks textile & finishes & several other applications. Having odorless & nontoxic properties, Polyvinyl Acetate Beads are resistant to attack by weak acids, alkalies & salts, but are soluble in many organic solvents. We offer the product at highly competitive prices.

Features:

  • High purity
  • Odorless
  • Nontoxic properties
  • At highly competitive prices

Prolonged immersion results in sight water absorption , Particularly in low viscosity grades

The viscosities of the B 15 , B 25 & ASB 516 beads are determined in a No 200 Ostwald - fensek Tube at 20 C . The viscosity of the B – 100 beads is determined by a Brook field Viscometer , Model RVO at 20 C with a No. 2 Spindle at 20 R.P.M. To make the determinations, the B grades are dissolved in toluene.
