Driven By Health features PU benefits


Pressure ulcers cost the NHS an estimated £1.4 - £2.1bn a year. So a simple change, such as ensuring your medical support surface cover is made of the correct material to help reduce and prevent pressure, can have a massive impact on the cost of pressure ulcer care.
Polyurethane (PU) and PVC are commonly used fabrics, and while they may look and feel similar, here are some good reasons why PU is a better choice over PVC when used in a medical setting.
Polyurethane is a unique class of polymer, which contains urethane linking groups that form long spaghetti-like chains. 
The chains are made up of a crystalline phase, which provides chemical durability and chemical resistance – and a soft phase, which provides the stretch and moisture vapour permeability properties.
These flexible, stretchable and breathable capabilities mean that polyurethane is a good choice for a medical support surface for patients with pressure redistribution and microclimate management needs.
Moisture vapour permeability (MVP) ensures that the moisture vapour from the body passes through the surface and away from the patient with ease and does not build up against the skin helping maintain a healthy microclimate at the patient interface.
Richard Haxby, Technical Manager at Dartex Coatings said: “The high stretch properties of PU ensures excellent envelopment and immersion of the patient and allows the benefit of the pressure redistribution technology beneath the surface to be fully realised.
PU is highly durable when used as a mattress cover, allowing easy cleaning and disinfection to contribute to patient safety from preventable harms.”
In comparison, polyvinyl chloride (PVC) is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.
