sight gauge and the tubing used in various critical bio-processing applications. This product is over-moulded onto the sight gauge to form a secure, hygienic gasket that is fixed with a mechani- cal clamp.
Anna Maria Bertasa, global marketing manager
for healthcare at Solvay Specialty Polymers, added: “Solvay takes a proactive approach to material testing to support the regulatory compliance needs of pharma industry customers. By delivering on all the stringent requirements of TBL’s Tri-Clamp sight gauges, Udel PSU demonstrates how critically important material technologies are to this fast- changing and demanding sector.”
offers the necessary strength, transparency, heat resistance and hydrolytic stability – as well as retention of mechanical properties under steam sterilisation – for demanding biopharmaceutical processing conditions. The material was used to extrude TBL’s Tri- Clamp sight gauges – after trials with polycarbon- ate had failed. One important factor was that it had gone through extensive testing. “Udel P-1700 PSU resin is a major breakthrough for the pharmaceutical industry,” said Robert DuPont, managing director of operations for TBL. “One key factor in choosing it is the rigorous regulatory testing done by Solvay – particularly for extractables and leachables under the BioPhorum Operations Group (BPOG) standard.” Solvay has taken a lead position in providing this
data to its customers, he added. Based on the resin’s performance – and the collaboration with Solvay – TBL is planning to expand the use of the material into novel products that are currently being developed. In addition, TBL chose an opaque, white grade of Udel PSU to create the connection between the
Polyimide extension US-based Zeus Industrial Products has extended its range of polyimide (PI) tubing by adding braid and coil-reinforced versions. Polyimides have high chemical, thermal and mechanical performance, and are typically used in applications such as vascular and urinary catheters. Braid or coil reinforced PI tubing helps engineers optimise catheter designs by fine-tuning properties such as flexibility, kink resistance and strength, says the company. “Recent medical advances mean we now use
catheters to reach areas of the body that were previously inaccessible,” said Rodrigo Silva, product manager at Zeus Industrial Products. “This requires more capable device designs and compo- nents. Our reinforced PI tubing helps address this, by providing device engineers with more options for optimising their designs.” Zeus customises its reinforced PI tubing based on customer specifications and requirements. Customers can order the product in various braid and coil patterns, and densities. The tubing can be produced with full load and
half load braid patterns, as well as in coil configura- tions. It is available with total wall thicknesses as
