CARB

Ravecarb are polycarbonate diols (PCD) which are aliphatic polycarbonate with molecular weight around 500-3000 and two

terminal OH groups PCD are increasingly well known and used intermediates for high performance PU systems in sectors like

synthetic leathers various coatings and resins for flooring or wooden surfaces paints elastomers adhesives sealants liquid

inks for printers etc

In all those sectors PCD are undisputedly considered as the ultimate solution in terms of quality improvement for mechanical resistance chemical resistance elongation

property UV resistance anti-scratch and anti-stain properties

The liquid versions of PCD support the production of higher quality synthetic leathers as they add a kind of ldquocosmeticrdquo touch to the finished material while guaranteeing all the other resistance properties solid PCD are appreciated for

Ravecarb were developed during the second half of 1980rsquo so that they can be considered among the oldest PCD available in the market

Caffaro Industrie SpA is proud to produce and trade Ravecarb polycarbonate diols and to make them available to a continuously increasing number of partners from everywhere in the world

CARB

Ravecarb are polycarbonate diols (PCD) which are aliphatic polycarbonate with molecular weight around 500-3000 and two

terminal OH groups PCD are increasingly well known and used intermediates for high performance PU systems in sectors like

synthetic leathers various coatings and resins for flooring or wooden surfaces paints elastomers adhesives sealants liquid

inks for printers etc

In all those sectors PCD are undisputedly considered as the ultimate solution in terms of quality improvement for mechanical resistance chemical resistance elongation

property UV resistance anti-scratch and anti-stain properties

The liquid versions of PCD support the production of higher quality synthetic leathers as they add a kind of ldquocosmeticrdquo touch to the finished material while guaranteeing all the other resistance properties solid PCD are appreciated for

Ravecarb were developed during the second half of 1980rsquo so that they can be considered among the oldest PCD available in the market

Caffaro Industrie SpA is proud to produce and trade Ravecarb polycarbonate diols and to make them available to a continuously increasing number of partners from everywhere in the world
