Performs with High Voltage and Excels in Overmolding
Florence, Ky., Sulzbach, Germany, Shanghai, PR China – RiteflexÂ® 640A thermoplastic polyester elastomer (TPC-ET) from Celanese Corporation (NYSE: CE), a global technology and specialty materials company, is the material of choice for medical cable and connector systems produced by Plastics One Inc.
"Whatever we design and build, Riteflex 640A is our 'go-to' material because it performs well with high voltage and excels in overmolding to a substrate," said Steve Heckman, senior research and development engineer at Plastics One of Roanoke, Va., which specializes in the design, assembly and molding of connectors and cables for customers in the global medical market. "We switched from commonly available copolyester and we’ve continued to grow and use Riteflex 640A."
Plastics One uses Riteflex 640A TPC-ET because it provides the right durability and balance of properties required for medical cable and connector systems designed for patient diagnostics and monitoring applications, nerve integrity monitoring, hearing enhancement, and sleep and respiratory studies.
Celanese will feature Plastics One medical cable and connector systems with Riteflex TPC-ET at MD&M West from Feb. 11 to 13 at Anaheim, Calif., in Booth 1945, which will include the dedicated Celanese portfolio of advanced medical materials — HostaformÂ® acetal copolymer (POM), CelanexÂ® thermoplastic polyester (PBT), FortronÂ® polyphenylene sulfide (PPS), VectraÂ® liquid crystal polymer (LCP) and GURÂ® ultra-high molecular weight polyethylene (UHMW-PE) engineered materials; AtevaÂ® Medical EVA polymers and VitalDoseÂ® EVA; and ClairfoilÂ® Acetate film.
"As a global solution provider with more than 50 years of material, component design and processing expertise, Celanese is helping Plastics One meet its material challenges," said Anthony Verrocchi, medical marketing manager - Celanese. "Riteflex 640A TPC-ET, which provides the required electrical insulation and material flexibility required by medical connectors and cables, is one reason why Plastics One is internationally recognized as a specialist in innovative custom design, tooling and medical molding."
Plastics One molds a variety of plugs, connectors and bend reliefs in various colors with Riteflex 640A TPC-ET, including:
• Cable Assemblies — Plastics One overmolds PVC wire jackets with Riteflex because the two materials bond well. The medical connectors, which must withstand 1,000 insertion cycles, incorporate sealed contacts to ensure efficient function, long-life and maximum signal transfer at the connection point.
• Medical Electrodes and Contacts — One-piece electrodes and contacts, which provide a patient interface such as snore sensors used in sleep studies, are molded by Plastics One using a two-shot process that pre-molds with Riteflex TPC-ET and overmolds to achieve cross linking.
• Jumper Cables — Plastics One uses Riteflex TPC-ET to mold fine detail on bend reliefs to enhance cable life.
• Touchproof Safety Plugs and Jacks — Plastics One uses overmolded Riteflex TPC-ET parts with integral bend reliefs or medical touch proof systems that meet the IEC-60601-1 standard.
"Several of our medical market applications use overmolded Riteflex parts because it plays well with PVC; the melt temperatures need to be similar so the PVC wire jacket doesn't melt," Heckman said. "These over molded parts include integral bend reliefs or medical touchproof systems that meet the IEC-60601-1 standard, which covers the overall electrical safety requirements for medical equipment connected to electrical mains."
Medical touchproof or "safety" connectors have evolved into a specialized class of connectors that fall under several international standards. IEC/EN 60601-1 is an International standard that covers the overall electrical safety requirements for medical equipment connected to electrical mains. It specifies overall test requirements that connection systems must meet.
Riteflex TPC-ETs combine toughness and resilience with excellent resistance to creep, impact, tear and flex fatigue. Specifically, Riteflex 640A TPC-ET:
• Performs well over a wide range of temperatures, from -40 degrees Celsius to 120 degrees Celsius (-40 degrees Fahrenheit to 250 degrees Fahrenheit)
• Delivers good impact resistance at low temperatures, while retaining useful properties at high temperatures
• Exhibits excellent chemical resistance to common solvents, fuels, oils and greases, dilute acids and bases
• Offers high Comparative Tracking Index (CTI) — up to 600 volts
