Condoms, which are controlled medical devices, are easily utilized as they are low cost and cause no side effects. Condoms are increasingly used as one of the most effective means of birth control and prevention of sexually trans-mitted diseases. When producing condoms, the dipping/drying processes are repeated twice during the molding. After being released from the mold, post-vulcanization is applied. The quality inspection of the finished products includes a bursting test which is used as a substitute for the “no tearing during use” test. Japanese condoms of a thickness of 0.03mm had been used successfully in the past. After introducing the bursting test into ISO 4074, the condoms being 0.03mm in thickness became problematic to produce. However, the subsequent development of new technologies again enabled the production of the condoms with a thickness of 0.03mm. These are more suitable to new competitive rules, and the production of the condoms continues to this day.

Rolling resistance of tires is a highly important property for tire development as well as tire traction. The rolling resistance is mainly generated by energy loss of tire components during tire deformation, because tires transform their shape from round to flat at their contact patch. It is known that to reduce the rolling resistance, tanδ of rubber around 10 Hz should be decreased. In general, silica filled rubber shows lower tanδ around 10 Hz compared to carbon black filled rubber. On the other hand, frictional force of rubber consists of two main terms. One is hysteresis term and the other is adhesion term. It is reported that silica filled rubber shows higher frictional force in comparison with carbon black filled rubber, because of higher adhesion component of friction. Therefore, silica filled rubber can improve not only rolling resistance but also traction of tires. X-ray and Neutron scattering results show that dispersed structure of silica agglomerates in rubber is different from that of carbon black agglomerates. It is considered that the good performance of silica filled rubber in rolling resistance and traction correlates to the silica dispersed structure in rubber.

It is well known that elastomer surfaces vary friction behavior with the sliding conditions. These frictional characteristics depend on interfacial dissipation of viscoelastic asymmetric deformation and adhesion. As adhesion plays a dominant role in such friction behavior at very low sliding velocities, adhesive friction of elastomer is focused and discussed. The one mechanism of adhesive friction force generation is macroscopic dissipation of fracture and healing of contact junction. The other one is microscopic dissipation of attachment and deformation of molecular chain of elastomer. It is shown that the combination of these two mechanisms can explain the friction characteristics at very low speed conditions.
