[Plastic] New energy vehicles put forward new requirements for plastics

With the rapid development of the automotive industry, especially the rapid development of new energy vehicles (including hybrid, pure electric and hydrogen energy) in recent years, the automotive industry has demand for lightweight, integration, miniaturization and electrification of auto parts It is also increasing day by day.

1.

The latest development trend of internal combustion engines is miniaturization and intake supercharging (that is, turbocharged high).

This design puts forward higher requirements for the high temperature resistance and high strength of the material.

2.

As more sensors have been arranged in various positions of the entire vehicle, the integration of electrification continues to increase, and the requirements for materials of these electrified equipment are more stringent than before, such as low precipitation (not to block the oil circuit of the capillary structure), Electrical neutrality (not to cause a short circuit in the circuit), materials need to meet the requirements of relevant laws and regulations (not to contain prohibited substances), etc.

Polyamide (nylon) materials are widely used in the automotive industry due to their excellent mechanical strength and long-term heat resistance.

So, what is a DPPD substance?

DPPD: Scientific name N,N'-diphenyl-p-phenylenediamine, density 1.

According to regulations and the urgent needs of the market, Rantic High-Performance Engineering Plastics has launched research and development for the requirements of "DPPD-free + excellent long-term heat resistance + electrical neutrality + low precipitation", and developed mature grades and their application.

3.

With the rapid development of new energy vehicles (including hybrid, pure electric and hydrogen energy), the relevant standards for parts and materials in this field are also rapidly refined.

Different flame-retardant systems have different flame-retardant effects, and at the same time have obvious changes in the physical properties of the material (such as density, rigidity, and toughness) (Figure 7).

4.

In addition, it is worth mentioning that in the high-voltage parts of new energy vehicles, according to regulatory requirements, it is necessary to use a bright orange material to mark the relevant parts as high-voltage areas.

In the future automotive industry, lightweight and weight reduction, electrification, high transmission efficiency, and miniaturization of turbocharged engines will inevitably be taken as a whole and become the indicators for the development and verification of most highly integrated auto parts.
