Alfa TWIN (PVC)
PVC (polyvinyl chloride) is one of the world’s most widely consumed and highly versatile plastics. The properties of this amorphous thermoplastic material are highly variable depending on the additives used. PVC characteristics include good self-extinguishing properties, toughness, good weather resistance (color and stiffness retention, impact resistance) and excellent dimensional stability.
ALFATWIN products are the coextruded solution of the rigid and plasticized versions of PVC.
