PVB Dispersions

POLYCOM is the only manufacturer in North America that recycles PVB into a water-based dispersion called EcoBlend. This unique solution can be used in multiple applications, such as adhesives, coatings, latex formulations, paint formulations, pre-coats, primers and more. EcoBlend helps customers incorporate upcycled materials into their products for post-consumer or post-industrial recycled content.

What Is PVB?

Polyvinyl Butyral (PVB) is a resin that was developed in 1927 and has many desirable performance characteristics, such as adhesion, binding, clarity, flexibility and toughness (see the bottom of the page for more properties).

One of its main uses introduced in 1938 was a film used in laminated glass, such as the kind found in car windshields and safety glass. PVB film is sandwiched between layers of glass by applying heat and pressure, increasing its impact resistance and keeps the glass from completely shattering when broken.

This PVB film is separated from the broken laminated glass and is recycled into chips or pellets that can be reclaimed, redirecting it from landfills.

Our EcoBlend Story…

POLYCOM developed its proprietary process to upcycle PVB chips and pellets into a water-based dispersion we call EcoBlend, while keeping its inherent, desirable PVB characteristics. Products utilizing EcoBlend support our manufacturer partners’ claims of post-consumer and post-industrial benefits to their end-use customers.

POLYCOM can adjust its EcoBlend formulation to meet customer specifications, address specific needs, or achieve intended application efficiencies.
