BASF Unveils New Ultrason P with Improved Flowability.

BASF is expanding its Ultrason[R] P product range with a particularly low-viscosity grade. The new polyphenylsulfone (PPSU) Ultrason P 2010, available in transparent and opaque, offers improved flow behavior in injection molding while maintaining the mechanical properties of Ultrason P, enabling the manufacture of larger, complex-shaped components such as dishes and heat-resistant containers with sophisticated, thin-walled geometries for catering and aircraft applications. This means that in processing raw material use, energy consumption and component weight can be reduced. The tool also fills up at lower injection pressures and processing temperatures.

The thermoplastic, approved for food contact in the European Union and the United States, combines the notched impact strength and stability of Ultrason P 3010 with high chemical resistance, hot steam sterilization at 1 34 C, and inherent fire resistance. The Charpy notched impact strength is almost ten times higher than that of other amorphous high-temperature materials, and even the combination of aggressive cleaning agents and disinfectants, water, and extreme heat does not affect Ultrason P 2010.

Catering and aircraft equipment are among the targeted application areas for the new material. In hotels, restaurants, and canteens, where the demands on sterilization and resistance to cleaning agents are very high, containers and pans made of the BASF PPSU can be used to prepare food as well as to transport meals and keep them warm. In aircraft construction, where fire resistance is of particular importance, the inherently flame-retardant specialty plastic, which in the event of fire releases little heat and hardly any harmful substances, offers optimal conditions--not only for serving dishes, but also for seat and lighting cladding, air vents, and overhead luggage compartments.

Ultrason is the trade name for BASF's product range of polyethersulfone (Ultrason E), polysulfone (Ultrason S) and polyphenylsulfone (Ultrason P). The material is not only used to manufacture lightweight components in the electronics, automotive, and aerospace industries, but also in water filtration membranes and parts that come into contact with hot water and food. Because of their property profile, the Ultrason brands can replace thermosets, metals, and ceramics.
