At the beginning of the year, the world's leading consulting firm Deloitte released a forecast: The company forecasts that annual sales of electric vehicles will continue to grow rapidly from 2 million units in 2018, and are expected to reach around 21 million units by 2030
.
The popularity of new energy vehicles has benefited from policy support and technological development.
At present, China has become the world's largest new energy vehicle market

The popularity of new energy vehicles has benefited from policy support and technological development.
At present, China has become the world's largest new energy vehicle market
.
However, in recent years, new energy vehicle safety accidents have occurred frequently, many of which are domestic and international well-known brands of electric vehicles spontaneously igniting, aggravating the public's concerns about the safety of new energy vehicles
.
The main reasons for the spontaneous combustion of electric vehicles include:
1.
The collision causes combustion;
2.
Insufficient heat dissipation of the battery causes combustion, which is common in static parking;
3.
The system short circuit causes combustion;
4.
There is a problem with the electronic control system, etc.
, burning during the charging process

Fundamentally solving the safety performance of battery electronic control is the technical bottleneck of current development
.
In the event of an accident, whether it is possible to ensure that the drivers and passengers have sufficient escape time has become a key consideration
.
Therefore, new energy vehicles should fully consider the use of flame retardant materials

.
Therefore, new energy vehicles should fully consider the use of flame retardant materials
.
The mechanism of action of flame retardant materials is mainly divided into:
1.
After the flame retardant is decomposed by heat, it releases a free radical blocker, which interrupts the flame reaction
.
2.
The flame retardant decomposes the polymer to form a foam layer under the action of combustion
.
3.
The polymer depolymerizes, takes away heat, and it is difficult for the temperature to rise
.
4.
The polymer surface is rapidly dehydrated and carbonized to form a coking layer
.
5.
The flame retardant generates combustion-inhibiting gas under the action of combustion
.
As the world's leading supplier of polyamide (PA) materials, all flame retardant products provided by Emmans are halogen-free and red phosphorus-free products with excellent electrical insulation properties, color stability and mechanical properties
.
It has been widely used in high-voltage connectors of new energy vehicles, motors, battery modules, cooling systems and charging guns
.
Including general flame retardant grade PA6&PA66, and high temperature resistant aromatic flame retardant grade PPA
