POM medical grade

TECAFORM AH MT

TECAFORM AH MT (POM-C/Acetal) is an engineering plastic that is resistant to multiple cleaning and disinfectants as well as to a number of solvents. Furthermore, TECAFORM AH MT can be hot steam sterilized by the medical industry's usual methods.

The fields of application are diverse and range from medical segments like joint reconstruction, traumatology, spine and many more. TECAFORM AH MT is particularly suited for use as sizing trials in knee, hip and shoulder replacement procedures and other surgical instruments. 

Biocompatibility

TECAFORM AH MT is suitable for all medical applications that require biocompatibility with limited contact with skin and tissue for up to 24 hours and, where applicable, indirect contact with blood.

TECAFORM AH MT plastics are tested according to ISO 10993

Key characteristics

A basic feature of TECAFORM AH MT is its strength. The material is stiff, firm and hard, has good sliding and friction properties and has very good electrical insulation. Other properties include:

  • High chemical resistance, especially to alkalis, solvents and fuels
  • High strength, hardness and spring stiffness
  • Low moisture absorption
  • Good dimensional stability

Steam sterilisation resistance 

Hot steam sterilization: TECAFORM AH MT shows no significant loss of mechanical properties up to 800 sterilization cycles. However, discoloration could be seen at 200 sterilization cycles. At around 500 sterilization cycles, color change (yellowing) could  also be seen. 
Sterilisation tests were performed using plastic test specimens without cleaning cycles. The sterilisation temperature was 134°C with a sterilisation time of 10 min. and a drying time of 20 min. The chamber pressure was 3 bar. Other effects influencing the cleaning process (with Ecolab, Borer etc.) were not investigated. Due to the chemical resistance of the individual materials and practical experience it must be assumed that the cleaning cycles have a significant influence on the sterilisation resistance. The sterilisation resistance, in particular of PP-HT and to a lesser degree POM-C, is significantly impaired by this. It must therefore be assumed that the sterilisation resistance will be significantly lower than described. We typically define PP-HT with approx. 200 sterilisation cycles and POM-C with approx. 300 - 400 cycles.
 

TECAFORM AH MT materials

Ensinger's POM-C medical grade TECAFORM AH MT is available in many standard colors from stock. This allows greater flexibility when designing your applications, e.g. to easily distinguish between different instruments and sizes, or differentiate from competitors' products by color branding. Also, TECAFORM AH MT rods can be ordered in a wide range of dimensions which offers our customers optimized supply chain coordination, thus fulfilling our customers' delivery time needs.
