Properties of Biaxially Oriented SPS BoSPS

Biaxial orientation is widely utilized because excellent balances of properties, such as high tensile strength, dimensional stability, transparency, and electrical properties, are provided. The amorphous web of SPS can be biaxially oriented [Pg.282]

The properties of a BoSPS film are sununarized and compared with bi-axially oriented films of other engineering plastics in Table 13.6. BoSPS has comparable mechanical properties with other engineering plastic films. Outstanding features of BoSPS are the dimensional stability against humidity, electrical properties, and transparency.
