Usual rubber, especially Chinese origin, possesses a pronounced unpleasant smell of which it is difficult to get rid. Other requirements are imposed to medical rubber. It should not contain harmful volatile compounds.
Properties of rubber
The rubber produced recently is not intended for commercial use. That it had useful qualities, it is necessary to enter various flying additives which cause an unpleasant smell into ready rubber. A number of molecules of these volatiles filter through rubber. As a result the smell can turn out very pungent and unpleasant. Especially considerably it in the Chinese rubber. Quality control here in general is lower, than on average in the world. And when goods from such rubber send by mail, in the closed boxes, without airing the smell concentrates. In a vacuum without access of air of a molecule are actively formed and concentrates.
Medical rubber
Special requirements are imposed to the rubber and silicone products intended for medical and food use. They have to be absolutely inert and not react on Wednesdays in which are used. Besides, medical rubber does not allocate any toxic connections during use. Medical rubber does not contain toxic chemical compounds, for example, of the peroxide vulcanizing agents.
Such silicone rubbers make in the course of additive curing, it is the system based on the platinum catalyst. It consists of various silicone bases, the sewing agent, inhibitor and the catalyst. The catalyst can be entered together with other parts, in that case rubber becomes single-component. Such technology is allowed too. Other way – the catalyst is entered just before application and rubber becomes pseudo-1-component.
Medical silicone rubber – material eco-friendly, it does not contain peroxides and products of disintegration. It has no toxic qualities and is not inert therefore it in any environments keeps the properties. Apply in medicine this material very widely. Do silicone tubes, catheters, packages, test tubes, probes, glue of it for medical plasters. For medical rubber there is no replacement when the major devices supporting human life in serious conditions become. Do devices for dialysis of it, drainage systems, devices for extracorporal blood circulation. Medical silicone rubber maintains wide temperature range: from-60 to +300 degrees Celsius. It is resistant to biological solutions, solutions of salts, the boiling water, phenol.
