The Duratron® family of products by MCAM (formerly known as Quadrant) has a highly versatile performance range which makes it useful in a variety of applications. Duratron® products include PI, PBI, and PAI high performance engineering grade plastics. These materials are generally able to withstand harsh thermal and chemical conditions in addition to stress. Alro plastics offers Duratron® products in several grades. Do you require high temperature resistance, high strength, or chemical resistance? Knowing the parameters of an application is key to selecting the best Duratron® product for your needs because each Duratron® product has its own set of key features and benefits. If you are looking for Torlon® PAI, or ULTEM® you are in the right place! In 2010 Quadrant EPP changed the names of their Torlon® and ULTEM® materials as follows:

• Torlon 4301 is now Duratron® T4301
