LinkTech to Unveil New High-Flow Coupling Made of Solvay's Udel PSU for Healthcare Industry

24 June 2014

LinkTech Couplings is ready to launch its 60PS series of high-flow couplings made of Udel polysulfone (PSU) resin from Solvay Specialty Polymers for healthcare and industrial applications.

The 3/8 in (0.95 cm) diameter high-flow couplings are described as being more durable and provide greater high temperature stability (up to 280°F/138°C) compared to competing thermoplastics like polypropylene (PP).

According to Solvay, the 60PS series features a new and improved panel mount design with a larger and more robust and reliable thumb-latch which makes the coupling more durable and easier and faster to use. The new coupling is also a replacement for brass in pressurised hot water applications thanks to Udel PSU’s compressive strength, high-temperature resistance, and autoclavability.

LinkTech Couplings explains it has a successful track record with Solvay’s line of sulfone polymers including Radel polyphenylsulfone (PPSU) for a range of quick coupling products. Radel PPSU has been used in couplings for sterilisation units due to its strong chemical resistance. ”Polysulfones are strong and easy to mould, making them highly suitable for these demanding applications,” said Hector Cordero, Design Engineer for LinkTech Couplings.

The multi-component injection moulded coupling, available in valved and non-valved configurations, are typically 2 in (5 cm) long, 1 in (2.5 cm) wide, and 1.25 in (3.1 cm) high, according to Cordero. They are available in up to 60 styles and can interconnect with all other 60 series LinkTech couplings as well as competitive high-flow couplings.

In healthcare, the 60PS high-flow couplings are used in repeated use and single-use applications in biopharma devices, surgical equipment, patient monitoring devices, and pressure therapy equipment.

Solvay claims that Udel PSU excels in many fluid handling applications and has successfully replaced brass in pressurised hot water applications for over 20 years. It exhibits low creep under a sustained load at elevated temperatures and can withstand continuous exposure to hot chlorinated water. It also features a heat distortion temperature (HDT) of 174°C (345°F) and is compliant with ISO 10993-1 for limited exposure, non-implantable applications.
