CCCorp. / American Cornerbead Company uses ABS (Acrylonitrile Butadiene Styrene) to manufacture its highly pliable and impact (dent) resistant plastic cornerbead profiles. CCCorp. / American Cornerbead Company uses ABS rather than PVC (Polyvinyl Chloride) because a fire will cause PVC to form hydrochloric acid fumes, which are a serious and deadly hazard. ABS is environmentally safer and gives you better mud and paint adhesion, increased flexibility and durability, greater resiliency and improved flange crack resistance from stapling and nailing. Our intricate pattern of holes on the flanges of the cornerbead allows the joint compound to penetrate through the flanges to the drywall and gives you a superior joint compound adhesion.
ABS is a common recyclable thermoplastic with a melting point of approximately 221o F (105o C). The most important mechanical properties of ABS are that is will never rust and is impact resistant. ABS is resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils.
