TECANYL MT (medical grade)

TECANYL™ MT is a new family of autoclavable materials developed for medical device applications. The material offers the desired performance properties of PPSU based resins with the machining ease and tool friendliness of acetal or POM. This allows part designers to take advantage of lower manufacturing costs by increasing output rates, and reducing tool wear, all without sacrificing part performance. TECANYL™ MT and TECANYL™ MT XRO™ shapes are all ISO 10993 tested to support their use in instrumentation that is intended to come in contact with blood and tissue for a period of not more than 24 hours. Ensinger can also provide TECANYL™ MT grades in finished injection molded parts for high volume applications.

  • Excellent autoclave performance comparable to higher temperature materials
  • Easily machined, producing high quality surface
  • No black speck generation as in sulfone polymers
  • Lower manufacturing costs
  • ISO 10993 Tested

TECANYL™ MT exhibits a broad range of outstanding properties for applications in medical devices where exposure to extreme heat and hygienic measures are demanded. Excellent wear properties, ease of quality machining and availability in a wide range of colors contribute to its desirability in medical devices.
