lately Electric vehicle helmet It has become the hottest product in the circle of friends. Why is the "electric helmet" on fire?
The General Administration of Transport of the Ministry of Public Security recently announced that it will carry out the "One Helmet One Belt" safety care campaign nationwide. The Ministry of Transport of the Ministry of Public Security requires the public security and transport departments in all regions to strengthen public relations and guidance, and improve the public's awareness of wearing helmets and using seat belts; This is a joint action by the competent department and the professional collective to promote "buying electric vehicles to send electric helmets" and "buying insurance to send electric helmets", and to implement demonstration and guidance for relevant key professions such as express delivery, take out, car rental and sharing.
In addition to the structural design, the safety of electric vehicle helmets depends on the plastic materials used by the manufacturers of electric vehicle helmets! The helmet of electric vehicle is generally composed of shell, buffer layer, windshield, buckle, etc. The shell plays the most important role in directly supporting the influence of external force. Generally, high-quality plastic is required as the primary raw material. So what kind of plastic should be used for electric vehicle helmets?
Manufacturers of electric vehicle helmets have considered various factors in the production process, such as impact resistance, rigidity, processability and plastic cost. We found that PC, ABS and PC/ABS can be used for most electric vehicle helmets. So what's the difference between them.
PC (Polycarbonate)
PC is an amorphous thermoplastic with excellent electrical insulation, expansion, dimensional stability, chemical resistance, high strength, heat resistance, cold resistance and excellent comprehensive functions. It is mainly used as the shell material of electric vehicle helmets, and mostly used in electric vehicle helmets, ski motorcycle helmets, mountain helmets, etc. PC has high light transmittance, and can also be used as lens information for electric vehicle helmets.
ABS (acrylonitrile butadiene styrene)
ABS engineering plastics have strong impact resistance and excellent dimensional stability. It is the most widely used plastic material for electric vehicle helmet shell in the market, especially its excellent safety function, so it is one of the most popular materials for consumers in the ski helmet, mountain bike helmet, motorcycle helmet and other markets.
PC/ABS alloy
Compared with ABS, PC/ABS is a modified material based on it, which significantly enhances the strength and toughness in function, and also greatly improves the low-temperature impact function. It also has excellent heat resistance, weather resistance, dimensional stability and impact resistance, and handles liquidity. Like ABS, it is also one of the first materials used for electric vehicle helmet shell.
