Abstract:
Male condoms are the main instruments of protection against sexually
transmitted diseases and birth control in the world and are produced mainly
from natural rubber. Since the 80s, with the significant increase in the use of
condoms, the industry has developed new models with different sizes,
thicknesses and tastes. With the increase in reported allergic reactions induced
for latex, models of condoms made from other materials such as polyurethane
have been developed. Studies suggest that polyurethane can be a good
alternative to latex, despite not having the same physical and chemical
properties. Since 2002 latex condoms are compulsorily certified by ANVISA and
INMETRO. Currently this certification follows the requirements established by
RDC 62/2008. Thus, this study aimed to determine if the minimum requirements
for rubber devices can be applied to polyurethane. For this, testing of
dimensions, thickness, determining the volumetric capacity and bursting
pressure, check for holes and integrity of primary packaging, the tests described
in RDC 62/2008 were performed, and also scanning electron microscopy, x-ray
diffraction, energy dispersive spectroscopy and mechanical testing. The test
results showed the differences in the physicochemical properties of materials
and the testing of the standard cannot be applied in full to polyurethane
condoms. According to the results it can be concluded that it is necessary to
establish standards for certification of polyurethane condoms, considering its
greater elasticity and lower resistance compared to natural rubber.
