Abstract
The permeability of gloves and differently formulated NR latex films to a challenge surrogate virus phi X174 of diameter 27 nm was assessed by a newly-developed method which could detect holes greater than or equal to 2 micro m. Samples from chlorinated and copolymerised natural rubber gloves and gloves with different extractable protein contents were found to be impermeable to the virus even when stretched 9 X their original areas. Similar results were obtained with samples from nitrile and vinyl gloves. The integrities of the latex films were not affected when the films were of different high-ammoniated latex concentrate sources different levels of non-rubber constituents different curing systems different moduli or different leaching protocols. The films maintaned their barrier properties even after being aged at 70 degree C for 7 or 14 days. These clearly showed that stretched latex films were not porous. Furthermore impermeability to a small virus such as phi X174 indicated that the films could also be impervious to human viruses such as hepatitis B or C viruses human immunodeficiency virus herpes simplex virus and cytomegalovirus which are up to five times bigger than phi X174.
