Rigid Polyurethane Foams for Electric Vehicle (EV) Batteries Advanced Insulation
Rigid polyurethane foams enter a small but growing niche of the electric vehicle battery market by providing a new approach to support battery safety aspects, thermal management, and even structural considerations. Perhaps better known for their insulation characteristics, these foams are major contributors to the general performance and reliability of electric vehicle batteries. While that is happening, the global electric vehicles market is rising; the role of such advanced material as rigid polyurethane foams to improve battery systems is also increasing.
These foams should be outstanding in their thermal insulation proper in such a way that the battery operates within the optimal temperature range. This is very crucial for maintaining the efficiency and longevity of batteries since high temperatures enhance faster degradation of battery cells. In addition to the above, rigid polyurethane foams are very good at fending off fire; they add an extra safety measure by reducing the risk of a condition known as thermal runaway. This is a condition in which the failure of one cell can lead to a domino effect and, in the end, can result in a battery fire.
Feature/Specification | Description |
Material Composition | Made from polyurethane (PU) and RPU (rigid polyurethane foam), providing exceptional durability, insulation properties, and support. |
Density | Ranges between 470-530 Kg/m³ for PU, ensuring lightweight yet effective insulation. RPU density is optimized for support in water-cooling plates. |
Hardness | Level of 65-70C for PU, offering resilience against physical stresses. RPU hardness is tailored for structural support in water-cooling systems. |
Flame Retardant | Rated at a V-0 flammability standard for excellent resistance to fire, applicable to both PU and RPU components. |
Impact Resistance | Engineered to withstand stone impacts, protecting the battery pack from external damages. Enhanced by RPU's structural integrity for added protection. |
Thermal Conductivity | Exhibits low thermal conductivity (<0.08W/m·K) for PU, enhancing insulation efficiency. RPU's thermal properties support optimal heat dissipation in water-cooling plates. |
Tensile Strength | PU boasts a tensile strength of 1-1.5Mpa, showing strong resistance to stretching forces. RPU complements this with high structural strength for water-cooling plate support. |
Elongation at Break | PU material stretches 200%-300% of its original length before breaking, indicating flexibility and durability. RPU maintains structural integrity under stress. |
Corrosion Resistance | Successfully resists damage from gasoline, acids, and bases, ensuring longevity in harsh conditions for PU. RPU additionally offers enhanced chemical resistance for water-cooling environments. |
Recommended Application | Easy application and removal with pressure-sensitive adhesive for PU, ideal for EV battery pack exterior. RPU serves as a supportive water-cooling plate padding, ensuring efficient thermal management and structural support. |
In addition to such aspects as thermal management and fire safety, rigid polyurethane foams increase the mechanical strength of the battery pack and also the vibration damping. Structural support would keep the sensitive battery components safe from mechanical shocks and vibrations during operation, thus ensuring battery life and stability of performance over time.
Our Rigid Polyurethane Foams is a crucial component for EV manufacturers seeking to improve battery safety and performance while adhering to environmental and safety regulations. For more information or to request a sample, please contact our silicone experts.
