Akestra™ 90

Akestra™ 90 by Perstrop is an amorphous thermoplastic copolyester. It is comparable to PETG in transparency, but has 10°C superior glass transition temperature and 20% higher flexural modulus. It possesses sparkling glass-like appearance, excellent clarity, excellent hydrolytic stability, heat resistance and high strength. It offers best mechanical properties for both cold & hot application and heat deflection temperature (HDT) 11°C above polyethylene terephthalate (PET). It is designed for film & sheet extrusion, blow molding and injection molding applications. Recommended for packaging. Akestra™ 90 can be used as a polystyrene alternative for heat resistant thin wall containers, a polycarbonate alternative for durable dishwasher proof transparent products and a glass alternative for hot-fill food containers.
