TECASON P MT (PPSU Medical) is a high performance medical grade plastic for applications with exceptional resistance to typical sterilisation methods, particularly hot steam sterilisation. Combined with its good resistance to detergents and disinfectants, TECASON P MT provides added safety for medical applications and can extend the life of applications even in demanding hospital environments. The applications for the material are extremely diverse and cover many areas of medicine, including joint replacement with artificial joints such as knee or hip replacements. But also in traumatology or spinal reconstruction, etc. TECASON P MT is often used for surgical instruments, tool handles, test implants (including femoral and tibial components for knee, hip and shoulder prostheses) and various sterilisation trays.
The material has high thermal resistance, excellent mechanical properties and toughness. In particular, PPSU offers very good impact strength, which helps to withstand shock stresses that offen occur during medical surgery. Other properties include:
Hot steam sterilisation: TECASON P MT shows no significant loss of mechanical properties until 800 sterilisation cycles. Also, significant discolouration is not seen below 1,000 sterilisation cycles.
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.
Ensinger's PPSU medical grade TECASON P MT is available in many standard colours 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 colour branding. Furthermore, TECASON P MT rods can be ordered in a wide range of dimensions, which offers our customers optimised supply chain coordination, thus fulfilling our customers' delivery time needs.
TECASON P MT XRO is a medical grade PPSU with good visibility and radiography. A contrast medium added to the standard TECASON P MT line permits clear visibility of components under fluoroscopy and X-ray radiation. It provides the surgeon with a precise picture of their instruments or of orthopaedic trial implants during image controlled procedures.
