High-flow polysulfone coupling for healthcare industry

Solvay Specialty Polymers : 22 July, 2014  (Application Story)
LinkTech Couplings, a supplier of quick couplings and valves is to launch its 60PS series of high-flow couplings made of Udel polysulfone (PSU) resin from Solvay Specialty Polymers for healthcare and industrial applications.
High-flow polysulfone coupling for healthcare industry

In healthcare, the 60PS high-flow coupling will be used in repeated use and single-use applications in biopharma devices, surgical equipment, patient monitoring devices, and pressure therapy equipment. It 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. 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 174C (345F) and is compliant with ISO 10993-1 for limited exposure, non-implantable applications.


 


The 3/8in (0.95cm) diameter high-flow couplings are more durable and provide greater high temperature stability (up to 280F/138C), compared to competing thermoplastics like polypropylene (PP). Solvay made the announcement at the Medical Design & Manufacturing (MD&M) East 2014 Exhibition 10-12 June in New York City.


 


LinkTech’s product range is well suited for use in durable and disposable medical equipment, analytical devices, food and beverage, and industrial applications. 


 


The company 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,” says Hector Cordero, design engineer for LinkTech Couplings.


 


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