VariCoat - The single-step process to coat wires

In the VariCoat process, wires, braids and fibers for medical use are extrusion-coated with a polymer layer. For the coating, RAUMEDIC uses only "medical-grade" plastics.

Plastic-coated wires, braids and fibers fulfill a wide range of medical purposes. They can be used as guides in minimally invasive surgery or as signal-transmitting electrodes for neuro-stimulation, for example.

With VariCoat, the medical technology manufacturer RAUMEDIC has developed a single-step process that makes it possible to uniformly coat wires, braids and fibers with a large number of high-temperature polymers, technical polymers and standard polymers. Instead of being applied layer by layer, polyamides (PA) and materials like PTFE, FEP, amorphous PEEK and PUR are directly extruded onto the substrate in a single processing step. The possible wall thicknesses range from 0.01 mm to 1.0 mm (0.0004" to 0.039").

The selection of substrates is virtually unlimited. With the help of the VariCoat process, wires and braids from conducting materials like stainless steel, copper and platinum alloys as well as glass fibers and synthetic Kevlar can be wrapped in a layer of polymer. The core to be covered can have a diameter of 0.025 mm to 1.5 mm (0.001" to 0.059").

RAUMEDIC produces the coated wires, braids and fibers exclusively under controlled clean room conditions of ISO Class 7. As a result, contamination by germs and particles is kept extremely low from the very beginning. In addition, the products can be further processed immediately afterward because no subsequent cleaning procedure is required.
