The materials-wide processing window and ease of thermoforming make them suitable for complex parts. In addition to availability in a wide range of integral custom colors and effects, no secondary processes are required to achieve desired aesthetics.

Thermoplastic butterfly valve from GF Piping Systems
Thermoplastic butterfly valve from GF Piping Systems
GF Piping Systems (GF) has added the 565 Butterfly Valve to its valve product offering. The new butterfly valve is strong yet lightweight, consisting of high-performance plastic components that include a polyvinylidene fluoride (PVDF) disc with fiber-reinforced polyamide housing and ethylene propylene diene terpolymer (EPDM) or fluorine rubber (FKM) seals, making it suitable for pressures up to 232 psi (16 bar) and temperatures ranging from 14°F/-10°C to 176°F/80°C.

Available in sizes from NPS 2 through 12 (DN50-300), the 565 Valve is 60 percent lighter than a comparable metal valve, allowing a single technician to handle it safely and easily during installation. The lightweight material also minimizes the energy consumed for transportation and installation. After installation, the advantages of the reduced static weight may also be significant in life science and water treatment skids.

“GF’s Type 565 Butterfly Valve solves all of the typical problems customers experience with metal valves,” said Kevin Coduti, GF’s valve and actuation product manager. “With its higher corrosion resistance, longer service life and more effective use of energy and resources during industrial production, our new Swiss-made valve provides a more cost-effective and sustainable solution. These advantages, combined with its quick installation and simple retrofit capability, make it the valve of choice for water treatment and many other applications.”

The new valve comes in the same installation length as metal valves (ISO 5752 Row 20, API 609 Table 2) so that retrofitting requires no additional work on the pipes or new designs. This feature reduces time in planning and installation. The new release from GF Piping Systems is made from superior thermoplastics for a longer lifespan in water applications, making it almost maintenance-free.

Advanced Bio-Circular polyamide 11 medical polymer from Arkema
Arkema announced a new high rigidity Advanced Bio-Circular polyamide 11 medical polymer intended to replace metal and traditional polymers. The new polymer offers physical performance, light weight and sustainability. Medical device manufacturers are concerned about improved corporate social responsibility (CSR) and climate change impact. Therefore, they are looking for materials that feature:

  • Biocompatibility
  • Performance on par with metal
  • Easy to process
  • Light weight
  • Allow for a perfect finish
  • High resistance to aggressive chemical agents and repeated sterilization cycles
  • More than 98 percent bio-based carbon — with a climate change impact that is typically 40-50 percent lower than competitive fossil-based alternatives; strong reduction in depletion of natural resources (fossil fuels)
  • Recyclable, especially as part of Arkema’s closed loop and open loop Virtucycle® recycling program

Arkema’s Advanced Bio-Circular (ABC) materials have a proven legacy in demanding applications. These bio-based, recyclable polymers are derived from Arkema’s flagship amino 11 chemistry, made from the oil of the renewable castor bean. Castor beans do not compete directly with the food chain and do not cause deforestation.

Formulated with a high content (65 percent) of glass fibers, the new Rilsan® MED polyamide 11 grade displays a tensile modulus of 18.5GPa, making it a suitable metal replacement for surgical tools. The new grade also requires low mold temperatures and injection pressures. Those properties helped early adopters switch materials easily and to decrease their cycle times significantly while maintaining component integrity.

In addition, this new material exhibits excellent resistance to gamma, steam, ETO and e-beam sterilization, opening new doors and opportunities for the development of sustainable reusable surgical tools and for the replacement of petroleum-based polymers. The biocompatibility of this new product has been successfully assessed according to USP Class VI, ISO 10993-4, ISO 10993-5 and ISO 10993-10 standards.

“We have found in this new product an ideal material for our surgical tools, easier to process than the polyarylamide (PARA) we were using before. Its bio-based nature has given us a real advantage to answer our customer’s drive toward more sustainable materials,” said Mark Jessup, managing director at Surgical Dynamics, one of the early adopters of this new Rilsan MED.

“Arkema continues to innovate to offer sustainable and recyclable materials, based on our proprietary polyamide 11 chemistry, to the most demanding and challenging markets. Our medical device customers are becoming more and more vocal on sustainability and Arkema is extremely well positioned to successfully help them transition to renewable materials and reaching their goals to reduce natural resource depletion,” said François Ruas, health and beauty global market manager, Arkema High Performance Polymers.

This new polymer is available worldwide and is sold by Arkema’s High Performance Polymers medical distributors.
