Polycarbonate medical industry

The chemistry of polycarbonates is similar to the chemical behavior of polyesters. We can think of a carbonate as being a diester of carbonic acid, H2CO3, which is unstable itself. Polycarbonate is a strong, clear plastic used in automobiles (25%), glazing and sheet (20%), optical media (15%), appliances (8%), computers (7%), medical industry (7%), and recreation and... 

The wide use of polycarbonate and flexible PVC in the medical industry resulted in the development of a range of adhesives which were not only considerably more flexible but also cured at the visible end of the UV spectrum (UW) 390-470 nm, thus overcoming the problem of absorbance at shorter wavelengths. Whilst these products are described as visible light curing adhesives, it should be noted that an investment in UV equipment is still required for rapid curing. 

Typical application areas for UV adhesives in the medical industry include the assembly of blood collection devices, endoscopes, hearing aids, IV sets, infusion pimps, catheters and diagnostic imaging equipment. The UV adhesive is often used to bond a stainless steel guide wire inside a polycarbonate luer or similar moulded part.
