Berkeley, California - DSM PTG, a subsidiary of DSM Biomedical, has launched Bionate II PCU, its new medical polymer with built-in surface technology designed for chronic (long-term) implants, the company said 21 Oct.
The new polymer is part of the firm's Bionate Polycarbonate Urethane family - a range of medical polymers for long-term implants. According to DSM, improved processing and performance characteristics include its patented SAME technology - a built-in surface modification utilising surface activity and self-assembly of chemical groups attached to the ends of each polymer molecule during synthesis. This, the statement said, can eliminate the need for secondary treatments.
"We believe Bionate II PCU with SAME technology offers a performance breakthrough in high-strength, biostable polymers for medical device designers," said Bob Ward, president of DSM PTG. "It is the next step in the continuous improvement of our biomedical thermoplastics, offering customisable surface chemistry for unique medical device designs," he added.
In the case of Bionate II PCU, "we have made minor changes to a proven polymer family that improve the polymer's processability and oxidative resistance, and significantly increase its strength," the DSM president concluded. (RD)
