What are the advantages of rolling plastic fuel tanks and iron fuel tanks?

Introduction to the advantages of rolling plastic fuel tanks compared to traditional fuel tanks:
1, Lightweight. When the engine power is constant, the lighter the weight of the car, the greater the effective load capacity. Therefore, designers start from the premise of saving fuel and try every means to reduce the weight of cars and improve their economy. Due to the relative density of plastic being only about 1/7 of that of metal, compared to metal fuel tanks of the same volume, the weight can be reduced by about 1/3 to half.
2, The design is casual. Modern cars are becoming increasingly compact in appearance and equipped with more and more features. Therefore, fully utilizing the available space in the car is an effective way to improve its usage rate. Due to the different manufacturing process of plastic fuel tanks compared to metal fuel tanks, a single roll molding process can be used to create complex shaped fuel tanks. Therefore, in the case where the overall layout of the car has been determined, the shape of the fuel tank can be adjusted to fit the spatial position, making full use of the remaining space on the chassis, expanding the fuel tank capacity, increasing the storage capacity of fuel, and increasing the driving range of the car.
3, It won't explode. Metal fuel tanks are prone to explosion in the event of a fire, posing a high level of danger. Due to the use of high molecular weight polyethylene material in plastic fuel tanks, their thermal conductivity is very low, only 1% of that of metals. At the same time, high molecular weight polyethylene is elastic and rigid. It still has excellent impact resistance and mechanical properties in environments ranging from minus 40 degrees Celsius to over 60 degrees Celsius, and is less prone to sparking when subjected to impact and friction. Even if the car accidentally catches fire, it will not explode due to the thermal expansion of the plastic fuel tank, and passengers in the car have sufficient time to evacuate.
4, Others. 100% cleanliness, anti-static, corrosion-resistant, easy to handle, shock resistant, impact resistant, especially in cold regions to prevent metal corrosion caused by ice and salt. Due to its high molecular weight stability, plastic fuel tanks have a long service life.
The rolling plastic fuel tank has excellent corrosion resistance to various acids and alkalis, with a streamlined appearance that is not easily dirty and can easily remove dirt. It is economical and durable, and the box body is integrally formed without adhesive joints, which is not easy to break. It has good heat and frost resistance, and the outlet joint is made of the same material as the barrel body, processed by hot melt bonding method, which can always save the trouble of liquid leakage.
