Which Parts Of New Energy Vehicles Need Flame Retardant Materials?

In recent years, with the large-scale popularization and application of new energy vehicles, the safety of electric vehicles has become the focus of users' attention. Among them, flame retardant materials can effectively reduce the occurrence of fire and other dangerous situations, which is an important means to protect the safety of new energy vehicles, so what parts of new energy vehicles need to use flame retardant materials?

1. Battery module

Battery module is a device for storing energy in electric vehicles, which consists of many battery cells. At present, the new energy vehicle industry has not yet standardized the voltage standard, so there are differences in the values of vehicle voltage adopted by various automobile companies. High-voltage voltage can reach 690V, and instantaneous pulse can reach more than 800V. Therefore, in order to avoid accidents such as spontaneous combustion or vehicle leakage caused by high temperature or voltage breakdown, it is necessary to apply flame-retardant materials in the pack shell of the battery module.

The battery pack shell can be made of cast steel plate, aluminum alloy, SMC composite material, carbon fiber reinforced composite material, long glass fiber flame retardant reinforced polypropylene material, PP-LGF35, PA66 and other flame retardant materials.

2. Automotive connector

Automotive connector contact parts are metal, insertion and removal times are high, need to have good flame retardant and heat resistance, the connector used more materials are PBT, PPS, PA, PPE, PET, LCP and so on.

3. Charging component

Charging component is an important part of new energy vehicles, mainly including high voltage parts such as charging pile, high voltage cable, high voltage connector and charging gun. The charger can guarantee the battery life of the car, but it may cause fire if overloaded and overheated, so the car battery charging components also need to use flame retardant materials.

4. Interior

In addition to battery modules and automotive connectors, the interior of the car also needs to use flame retardant materials. The interior includes seats, steering wheels and other parts of the car, and the materials can be roughly divided into fiber textile and leather, plastics, rubber, composite materials, etc. These materials are flammable and combustible, when a fire occurs in a vehicle, the combustion of the interior materials will cause harm to the people inside the car, so the flame retardant car interior is also important for safety.

5. Exterior Bodywork

Exterior bodywork also requires the use of flame-retardant materials. Although burning cars are uncommon, flammable materials can lose control of a fire if the car is involved in a collision or accident. Flame retardant materials can increase safety and reduce fire hazards.

6. Automotive cables

Different from the traditional wire and cable, automotive cable because of its application environment specificity, the material has very high requirements. In addition to ensuring insulation and also have a certain degree of high temperature resistance, aging resistance, and in the combustion of halogen-free flame retardant and low smoke density.

In conclusion, the fire prevention measures of new energy vehicles need to pay attention to a lot of points, involving a number of vehicle components, the battery field also uses a lot of new materials and structures, such as high-strength composite carbon fiber, high-strength steel and aluminum composite, etc.. In addition, under the dual-carbon background, more and more car companies are beginning to increase R&D investment in the field of new energy vehicles, so there will be more development opportunities in the field of fireproofing materials in the future.

With the widespread adoption of new energy vehicles, ensuring their safety has become a critical concern. Flame retardant materials play a vital role in reducing the risk of fires and enhancing vehicle safety.

As the automotive industry continues to improve its requirements for material performance, Yinsu Flame Retardant Company has kept up with market demand and developed a series of high-performance flame retardants, which are particularly suitable for automotive materials such as PP, PA, and ABS. Such as red phosphorus flame retardants PPV0-P-32M, PPV2-6, and PPV2-8H, along with piperazine-based flame retardant PPAP-15. These flame retardants not only have excellent flame retardant effects, but also meet the increasingly stringent safety standards of the automotive industry while ensuring material performance. Our products have been widely used in many automotive fields, providing a strong guarantee for automotive safety and promoting the continuous advancement of industry technology.
