This article introduces advantages of rotomolding fuel tanks in detail.

1. Light-weighted. When the engine power is the same, the lighter weight of car, the grater carrying capacity the car has. Therefore, designers tried best to lighten the car’s weight in order to save fuel. The relative density of plastics is only about 1/7 of the metal, compared with the metal fuel tanks with the same volume; the rotomolding tanks can reduce the car weight to one third.

2. Various modeling. Nowadays, the appearance of cars is more and more diverse and the device of cars also become more and more, so take fully advantage of space in cars is an effective way to improve the utilization ratio of cars. The manufacturing process of rotomolding fuel tanks is quite different with metal fuel tanks. The rotomolding fuel tanks applied rotational molding, it can be made into complex shapes to fix the space of car. Thus, the rotomolding fuel tank can make full use of the space and enlarge the volume of tank, improve the storage of fuel and increase the mileage of cars.

3. Won’t explode. When a fire happens, the metal tanks are prone to explode and it is extremely dangerous. The rotomolding tanks are made of PVC, and have low thermal conductivity, only 1% of the metal. At the same time, the PVC has excellent flexibility and strength, even in the extreme hot or cold condition; it still has excellent impact resistance and mechanical properties. Even if the car is on fire, the rotomolding tank is not going to explode, so the passengers will have enough time to escape. 

4. Other advantages. The rotomolding tanks are very clean and have special properties like anti- static and anti- corrosion, especially in the extreme cold areas; the rotomolding tanks can anti- metal corrosion. Due to the stability of high molecular, the service life of rotomolding tanks can reaches to ten years or more.
