What are the advantages of Rogers metal foam in the field of new energy vehicles?
The foams used by Rogers in the field of new energy vehicles are mainly polyurethane foams and silicone foams, but not nonmetallic foams. Its advantages mainly include the following points:
Excellent cushioning and vibration isolation performance: Rogers' poron polyurethane foam, such as PORON EVextend 43 series, has a unique "ideal curve". The hard front end can reach the designed rebound force under a small compression ratio, the flat middle can provide stable rebound force for the whole life cycle of the battery, and the soft back end can be compressed to the maximum extent, leaving room for battery design. It can not only effectively absorb the physical expansion of the battery during charging and discharging, but also inhibit the generation of lattice defects inside the battery and prolong the service life of the battery.
Good sealing performance: Rogers' BISCO HT-800 medium hardness porous silicone foam has excellent slow resilience and low stress relaxation, which can reduce gasket failure caused by compression deformation and softening. Its compact pore structure and unique formula can provide enhanced sealing performance, resist the invasion of fine particles and wind and rain, and prevent the leakage of gas, liquid or other pollutants between the internal and external environment of battery Pack.
Excellent compression deformation resistance: PORON foam, such as PORON 4701-37-14256-04, has a thickness change of less than 10% after 500,000 consecutive compressions, and can maintain the shape and sealing effect for a long time, ensuring that the shell and component system can remain sealed under long-term harsh use conditions, and reducing the need for maintenance and repair.
Wide temperature adaptation range: BISCO HT-800 material can work at the extreme temperature of-55°C to+200°C, and is suitable for battery systems in various environments to ensure the stability of battery performance.
Excellent flame retardant performance: HT-800 material conforms to UL 94 flame retardant standard and has good flame retardant performance, which can delay the heat spread when the battery is abnormal and improve the safety of the battery system.
Environmental protection and reliability: Rogers foam is halogen-free and antimony-free, conforms to environmental protection standards such as RoHS and REACH, and can directly contact with optical components and metals, without causing harm to the environment and human body. Moreover, its chemical composition and cell structure design make it have a long service life and can maintain stable performance in the long-term use of battery Pack.
Processing convenience: Some Rogers foam coils, such as PORON 4701-37-14256-04, can be die-cut, laser-cut, or die-cut into any shape, with neat edges and self-adhesive surface, and can be positioned by tearing off the PET release film, which is convenient for assembly in the production process of new energy vehicles and improves production efficiency.
