Arnite® AV2 370 XT

35% Glass Reinforced, Applications with extremely narrow tolerances

General Information

Arnite® (PBT, PET and blends) are high-performance engineering plastics that combine high strength and rigidity with excellent processing characteristics. As a result, Arnite® A (PET)  and Arnite® T (PBT) are well suited for a broad range of automotive, electrical & electronic and consumer goods applications.
A wide portfolio of Arnite® is available including unreinforced, reinforced and flame retardant grades.
