ORINKO Innovative Materials | Providing advanced protection solutions for new energy battery safety

As the market share of new energy vehicles exceeds 50% in April 2025, how can we build a solid safety line while enjoying green travel? Battery safety has always been the focus of the industry. Under current technical conditions, the risk of battery thermal runaway still needs to be addressed through a system protection system. Based on industry needs, ORINKO has developed ablation-resistant PPS materials to provide new technical options for battery pack protection.

ORINKO ablation-resistant PPS material

Redefine battery protection standards

Pain point upgrade: from "flame retardant" to "ablation resistance"

Traditional flame retardant PP materials used as battery covers have poor high temperature resistance and are easily burned through in the event of fire, making it difficult to balance lightweight and reliable flame retardant insulation.

Solution

ORINKO launches ablation-resistant PPS material solution. It uses high-performance engineering plastic PPS as the base material, which is naturally endowed with excellent mechanical strength, high fluidity, dimensional stability, chemical resistance and inherent flame retardant properties, making it an ideal cornerstone for creating ablation-resistant protective materials.

ORINKO's ablation-resistant PPS material has three major characteristics

ORINKO's ablation-resistant PPS material uses high-performance engineering plastics as the base material and achieves the following technical indicators through formula optimization:

• High temperature ablation resistance: In the 1300℃ flame direct burning test, the 1.5mm thick sample can be maintained for 10 minutes without penetrating damage.

• Mechanical performance advantages: The tensile strength exceeds 150MPa and the bending modulus is greater than 13000MPa, which meets the strength requirements of battery pack structural parts.

• Dimensional stability: After the "flame burning-high temperature sandblasting" cycle test in the UL2596 standard, the material shows good structural stability under simulated extreme working conditions.

Material value: multi-technical collaboration

Technical supplement for passive protection: As a battery pack shell material, it can complement active protection technologies such as BMS thermal management system and battery cell safety design to improve the vehicle safety system;

Balance between lightweight and safety: ORINKO's ablation-resistant PPS material density is about 1.7g/cm³. While meeting high strength requirements, it can achieve weight reduction compared to metal materials, which is in line with the lightweight trend of new energy vehicles;

Process adaptability: The material has good fluidity and can be adapted to the injection molding of complex structural parts. Currently, it has been verified with many OEMs.

Protecting a safe journey in the name of materials

Battery safety is the result of the collaboration of multiple technical dimensions. ORINKO has always believed that the application of ablation-resistant materials needs to be deeply integrated with vehicle safety design, battery management strategies, etc. In the future, ORINKO will continue to invest in material technology research and development to provide the industry with more verifiable and traceable safety solutions to help continuously improve the safety level of new energy vehicles.
