High Performance Plastics
Processing Range
High performance plastics such as PEEK, PEI, PSU, FEP, PFA and PTFE are characterized by their extraordinary properties in various areas. High performance plastics are primarily used where highest demands are placed on the mechanics, the chemical or thermal resistance or on the slippage of the products. PEEK, in particular, is an excellent metal substitute for medical applications where the biocompatibility of the material is important.
An example of high requirements on the plastic represents the multiple sterilisation cycle with hot steam which is usually only possible with metal-based materials. The extremely high pressure requirements for thin walled extrusions can only be met by using high performance plastics, too.
Fluoropolymers
Fluoropolymers such as FEP, PFA and PTFE also belong to the category of high performance plastics. These fluoropolymers are very resistant to nearly all chemical compounds and solvents. Distinguishing features of FEP, PFA and PTFE are their excellent sliding characteristic and very good biocompatibility.
Raumedic processes a wide range of thermoplastic fluoropolymers. We produce coils and fixed lengths for your required dimensions, which are ideally suited for their respective purposes. In addition, we can incorporate X-ray stripes in different numbers and shapes, or offer full contrast tubing.
PTFE Moldflon™
This material opens up completely new possibilities for a variety of medical engineering products. Raumedic processes PTFE Moldflon™ into tubing and profiles for medical and pharmaceutical applications in the clean room.
A special feature of PTFE Moldflon™ is that this material largely corresponds, in its composition, to conventional polytetrafluoroethylenes. Moreover, PTFE Moldflon is suitable for thermoplastic processing. In contrast to typical PTFE, which is produced in a sintering process, PTFE Moldflon™ provides an easy access to endless profiles and tubing.
In other words, PTFE Moldflon™ combines the positive properties of conventional PTFE and FEP. The following table demonstrates the properties of PTFE Moldflon™ versus PTFE and FEP by listing them side by side.
| PTFE | PTFE Moldflon™ | FEP | |
|---|---|---|---|
| Transparency | - | + | + |
| Slippage properties | ++ | ++ | + |
| Abrasion resistance | - | ++ | + |
| Biocompatibility* | + | + | + |
| Chemical Resistance | ++ | ++ | + |
| Thermoforming | - | + | + |
| Longitudinal tear resistance | - | + | + |
