Raumedic Are Achieving Enhanced Sliding Properties In Thermoplastic Products
Medtech company, Raumedic announces new
biocompatible additive which aims to enhance the sliding properties of medical
This new additive can be added to thermoplastic
elastomers, polyamides, polystyrenes and polyolefin, and has been tested in
combination with a base polymer over the last six months.
The mix of materials claims to significantly lower
the coefficient of friction, and thus improve sliding properties, whilst
ensuring there is no effect on parameters such as dimension, stability, flow
rate and tensile strength.
Katharina Neumann, head of the materials chemistry
department, Raumedic commented: “We see tremendous improvement potential for our
catheter products because they are easier to introduce into the body thanks to
their reduced gliding force.”
It is hoped that this additive will ensure the
optimisation of devices within areas such as regional anaesthesia, drug delivery
and minimally invasive surgery. Additionally, Neumann believes that the material
could potentially lower costs due to the high price of thermoplastic
polytetrafluoroethylene compared to this new compound.
Neumann concludes: “The additive can be used for all
applications in which plastic has to glide well on plastic."
