What are the application effects of Rogers foam new energy vehicle?

Rogers foam has the following application effects in new energy vehicles:

Sealing aspect

Battery pack sealing: Rogers' BISCO® HT-800 silicone foam is used to seal the battery pack shell. It has moderate hardness, conformability and durability, excellent compression deformation resistance, stable resilience and stress relaxation resistance, and can bring long-term stable sealing performance. The waterproof grade reaches IP6K/9K, which can effectively block the invasion and overflow of liquid, prevent external water and other foreign bodies from invading the battery pack, meet the requirements of the protection grade of the electrical equipment shell and ensure the safety of the power system of electric vehicles.

Sealing between motor and wiring harness: it can ensure the normal operation of motor and wiring harness in humid environment, avoid short circuit or performance degradation caused by water ingress, and provide reliable waterproof sealing protection for motor and wiring harness parts of new energy vehicles.

Sealing between car body and interior: used in sealing strips of doors, windows, skylights and other parts, it can effectively improve the waterproof performance of car body, prevent rainwater from penetrating into the car, and also play a certain role in shock absorption and sound insulation.

Shock absorption and buffering

Shock absorption of battery: between battery cells, foam can play a role of heat insulation and buffering when the cells expand when they heat and contract when they shrink; When the battery core is out of thermal control, foam can prevent the heat transfer, which has flame retardant performance and can protect the battery safety.

Integral vehicle damping: used in suspension system and chassis damping pad, it can effectively absorb and disperse the vibration and impact from the road surface, reduce the noise and bumpy feeling, and provide a stable riding experience for drivers and passengers.

Thermal insulation

Battery thermal insulation: In the battery pack of new energy vehicles, the battery monomer will generate a lot of heat during charging and discharging. The excellent thermal insulation performance of Rogers foam can effectively reduce the temperature rise of the battery, prevent the battery from overheating, and improve the safety performance and life of the battery.

Support aspect

Support in the battery pack: It can play a supporting role when it is located under the liquid cooling plate or next to the upper and lower box covers. For example, Rogers polyurethane foam can maintain its integrity and effectiveness in gap filling, gasket and vibration isolation applications, meet the requirements of fixing and sealing smooth parts of various parts, and is suitable for unstructured fixed sealing of light and small materials.

otherwise

Pressure management: Rogers also has professional material solutions in pressure management between cells to help maintain reasonable pressure between cells.

Air pressure management: it is helpful to manage the air pressure in the battery pack and ensure the stability of the battery pack under various environmental conditions.
