SPX™ is a high-end material whose exceptional properties make it ideally suited for use in the eyewear industry. Flexibility and tensile force resistance guarantee top stability. The high surface hardness renders the frame scratch- and abrasion-resistant and ensures long durability. Pleasant wearing properties and maximum comfort are results of the low specific weight of 1.04 g/cm3. Moreover, the minimal water absorption of SPX™ safeguards dimensional stability and resistance to variations in temperature.
