With the growing demand for clean energy vehicles, people are constantly searching for safe and long-range material solutions. Wanhua Chemical, with its continuous R&D efforts, is providing a polyurethane solution for clean energy battery systems.
HP-RTM polyurethane battery case
It provides a light and safe alternative for battery housing cover.
- 40-50% weight reduction compared to aluminum alloy, excellent strength, rigidity, and flexibility
- UL94 V0 in flame retardant test with only 0.8mm thickness
- Excellent insulation, highly compatible with battery pack system applications
- 0.26 W/m·K thermal conductivity coefficient, good temperature resistance and thermal insulation
- Fast curing, easy demolding, low energy consumption, efficient in mass production
Lightweight flame-retardant bottom protective plate
It adopts PU sandwich composite, so no need for additional layers. The upper and lower skins are produced by HP-RTM process, and only PU material needs to be injected during production.
- Only 0.05 W/m·K of thermal conductivity coefficient, excellent thermal insulation
- UL94 V0 in flame retardant test, without being burned through for 10 minutes at 1000 ℃
- Deformation <2 mm under 120J impact energy
- With a density of 0.6 g/cm3, 50% weight reduction compared to traditional steel+PVC plate
Impact-resistant and flame-retardant pultruded material
It is composed of glass fiber reinforced polyurethane pultruded composite, which provides a strong structure perpendicular to the driving direction, improving the structural strength and impact resistance of the battery pack.
- Low density, high strength, high modulus
- Excellent thermal insulation
- Low linear expansion coefficient
- Ideal electric insulation and flame retardancy
- Suitable for corrosive and low-temperature environments
Impact-resistant coating for automotive
It is mainly used for compartments like automotive power battery house cover and bottom protective plate that require extra protection for stone impact. It features excellent thermal insulation, physical properties, and good operability.
- Electrophoretic aluminum plate spraying process with a spraying thickness of 0.3-0.8 mm
- Simple process, fast spraying and curing, no need for baking
- High production efficiency, surface tack free within 1-2 minutes after spraying, production cycle < 3 minutes
High strength and resilient buffer material
It can significantly reduce the impact on the battery pack what vehicle collisions happens.
- 5 minutes automated production
- High flame retardancy, high interval compression strength, high elasticity, improved vehicle side collision resistance
- Reduce the risk of thermal runaway in the event of battery pack collision
Looking ahead, Wanhua Chemical will continue to collaborate with a diverse range of partners to offer innovative products and solutions in the clean energy field. We are committed to fostering a sustainable future for our global community.
