Eight automakers from Germany and the United States (Audi, BMW, Chrysler, Daimler, Ford, GM, Porsche and Volkswagen) announced that they will adopt a unified charging interface in the future. This new charging standard interface is named "DC Fast Charging with a Combined Charging System" and is compatible with 4 charging methods. Including single-phase AC, fast three-phase AC, home DC and public ultra-fast DC. These four charging methods can be completed through a unified charging interface, allowing the user to complete charging under different conditions. More importantly, the device is also capable of performing a fast charge operation of 15-20 minutes. According to General Motors, this joint charging method can reduce the cost of research and development and the complexity of the infrastructure, and can improve the reliability of charging and reduce the daily use of the owner. The new joint charging method will be presented at the 29th Electric Vehicle Symposium. Official mass production products are expected to be launched later this year, and the first electric vehicles using this technology will not be available until next year. Building Waterproof Material RDP Flexible Crack Resistant VAE (Vinyl Acetate-Ethylene) is a type of copolymer emulsion used in the formulation of flexible coatings and adhesives. It is specifically designed to provide excellent flexibility and crack resistance in various applications.

The crack resistance of VAE is achieved by the incorporation of ethylene monomer units into the vinyl acetate polymer chain. The presence of ethylene units enhances the polymer's ability to withstand stress and deformation, preventing the formation of cracks even under dynamic conditions.
Flexible crack resistant VAE is commonly used in the production of flexible coatings for applications such as waterproofing membranes, roof coatings, and sealants. It offers excellent adhesion to various substrates, including concrete, metal, and wood. The flexibility of the VAE emulsion allows it to accommodate substrate movement and prevent crack formation.
In addition to coatings, flexible crack resistant VAE is also used in the formulation of flexible adhesives. It provides strong bonding properties while maintaining flexibility, making it suitable for applications where joint movement is expected, such as in construction and automotive industries.
Overall, flexible crack resistant VAE is a versatile material that offers excellent flexibility and crack resistance. Its properties make it an ideal choice for various coating and adhesive applications where durability and long-term performance are required.
