Yokohama Rubber significantly reduces weight of automotive air-conditioning hose by using a rubber–resin polymer

The new ultralight hose is made from a rubber–resin polymer alloy developed by applying Yokohama Rubber’s proprietary technologies. This new alloy combines the flexibility and heat resistance of rubber with the high gas barrier properties of resin, and its use enabled Yokohama Rubber to reduce the hoses’ weight by 50 percent. In addition, hoses made using this alloy do not need to be put through a vulcanization process that uses a large amount of heat. The new hoses will therefore contribute to the effort to achieve carbon neutrality. One of Yokohama Rubber’s strengths is its design and evaluation capabilities that enable it to integrate hoses and pipes in ways that respond to various customer requirements and piping layouts. The company plans to develop and promote all-resin piping to achieve a significant reduction in the weight of hose and pipe combinations. While continuing to develop a commercial version of this new lightweight hose, Yokohama Rubber also aims to enter the market for other types of automotive pipes.

Seals prevent bearing damage in EVs

Freudenberg Sealing Technologies’ new generation electrically conductive seals prevent bearing damage caused by electrically induced corrosion, and also increase electromagnetic compatibility. Electric cars with drive systems that operate at 800 volts instead of the usual 400 can recharge in just 15 minutes, and produce enough power to drive several hundred kilometers. The power semiconductors in the inverter ensure that the direct current stored in the battery is converted into the alternating current required by the electric motor while driving. These power electronics are often positioned directly above the electric motor, and are also known as electric engine injection systems.
