This report introduces the feature and the technology trends of rubber cables for power generation plants and the transmission and distribution of electricity. In nuclear power plants, the radiation resistant ethylene-propylene rubber cable is used and requested longer service life, 60-80 years, for the purpose of plant life extension. In wind power plants, high voltage cable is used and required superior low temperature distortion resistance.The cables in photovoltaic power module demand the weather resistance, especially ultra-violet resistance. Halogen-free polyolefin and ethylene-propylene rubber are used. In the field of the transmission and distribution of electricity, rubber block joint is used to connect power cables, which utilizes the rubber elasticity. Ethylene-propylene rubber and silicone rubber are used in this application and it is requested to achieve both high dielectric breakdown strength, good workability which means cold shrinkable property around –40 °C, and relatively low cost.

Gas permeability of high polymer is important as a physical property in the gas barrier evaluation of vehicle tires and some fuel hoses from the viewpoint of energy-loss. The precise measurement of permeability rate of oxygen and steam is recently required in the field of organic EL display and fuel cell.This review describes the well-known mechanism of the gas permeability in the elastomers and the classification of gas transmission rate measuring methods as standard testing methods. The relationships between gas permeability and manufacturing process factors are also introduced. By using L18 orthogonal array, the results allow not only specifying effective factors and levels but also optimizing those for gas barrier property. Among the eight factors examined, primary factor of gas permeability is found to be the type of polymer, followed by the shape of inorganic filler, while the crosslink density of vulcanized rubber is not so influential.

We succeeded in developing the highly porous Cellulose Nanofiber nonwoven fabrics sheet, CNF sheet, composed of cellulose nanofibers (average fiber diameter: ranging of 30- 400 nm). CNF sheet has multilayered structure constituted of network plane of nanofibers over at least 50 layer. Therefore, with increasing in weight of CNF sheet, the pore size becomes to decrease and have the narrower pore size distribution. CNF sheet is corresponding to a heat resistant material (usable up to 200 °C, showing no glass transition temperature, low coefficient of thermal expansion (CTE): below 10 ppm/K as the CTE value between room temperature and 200 °C), and has very small pore size (maximum pore size: ranging of 0.06-2 micro meters), furthermore, has very large surface area (specific surface area by B.E.T. method: 7-100 m2/g). These unique features of CNF sheet would lead to the applications in wide industrial field, such as functional filter, substrate material for a low CTE hybrid film and for a medical use.

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.
