Due to increasing market demand for higher performing biocompatible composite solutions, AGY (Aiken, S.C.) has added to its S-3 Glass family of special-grade products a new glass fiber biomaterial reinforcement, targeted to the medical device implant market. The new biomaterial, trademarked HPB glass fiber, is suitable for long-term implant applications of over 30 days and is compatible with a wide range of thermoplastic polymers, such as polyetheretherketone (PEEK), polyetherimide (PEI) and polyphenylene sulfide (PPS). The fibers are said to have 40 percent higher tensile strength and 20 percent higher tensile modulus compared to standard E-glass fibers. AGY reports that it has applied the material in composites for dental implants, crowns and bridges. Potential applications may include other medical device applications that demand a biocompatible structural composite reinforcement, such as orthopedics. HPB glass fiber is available in a wide range of chopped, yarn, and roving formats, individually tailored to the demands of the customer.
