Abstract
A method for making an essentially natural rubber latex-free elastic compression bandage. The method includes providing a homogeneous mixture containing from about 20 to about 90 parts by weight synthetic natural rubber, from about 10 to about 80 parts by weight secondary elastomeric compound, fillers and processing aids. The mixture is fed to an extruder to provide an extruded web. The extruded web is calendered to provide a calendered web, and the calendered web is electron beam cured to provide an elastic web having a reduced bio-burden. The reduced bio-burden of the web enables production of bandages without prolonged sterilization techniques.
Claims14
A process for making an essentially natural rubber latex-free elastic compression bandage comprising, providing a homogeneous mixture containing from about 10 to about 70 percent by weight synthetic natural rubber, from about 5 to about 60 percent by weight secondary elastomeric compound, from about 15 to about 35 percent by weight inorganic fillers, and processing aids, feeding the homogeneous mixture to an extruder to provide an extruded web, calendering the extruded web to provide a calendered web, and electron beam curing the calendered web to provide an elastic web having a reduced bio-burden, wherein the percentages by weight of the mixture or based on the total weight of the mixture.
A natural rubber latex-free elastic bandage or band comprising an electron beam cured mixture containing from about 20 to about 90 parts by weight synthetic natural rubber, from about 10 to about 80 parts by weight secondary elastomeric compound, inorganic fillers and processing aids, wherein the bandage or band exhibits a bio-burden level which is achievable only by prolonged sterilization techniques.
