PP plastic belongs to the thermoplastic group, which is not only durable but also resistant to heat and chemicals from the surrounding environment. In addition, the weight of PP plastic is quite light, only about 0.85g/cm3 (in the form of plastic particles) and 0.95g/cm3 (in the form of crystals), improving the weight, aerodynamics and fuel economy of the car.
Next, PP plastic is also highly appreciated by manufacturers for its adaptability in the processing process, easy shaping as well as harmony with plastic additives. We can see that PP plastic is one of the perfect choices for plastic materials used to make electric car doors because of its outstanding properties and stable price.
PVC plastic is considered by manufacturers to be one of the materials that consumes the least resources, energy and costs in the final product production process. In terms of density, PVC ranges from 1.23 to 1.46g/cm3, higher than other plastics in the same segment such as: PE, PE. In addition, PVC.S plastic has a fairly large particle size from 20 - 150 micro. Therefore, they are not only durable but also possess an impressive hardness in the range of 5000 to 8500. In particular, the compressive strength of PVC material reaches nearly 10000 psi. These are very suitable factors for the door part to ensure that the electric car is operated in a balanced, stable, durable manner against environmental impacts as well as ensuring safety for the driver.
Meeting the criteria of comprehensive "greening", electric car doors made from PVC can be recycled into many different products without affecting the environment. Besides doors, PVC plastic is also used to manufacture many devices on electric cars, specifically: Windshield systems, control panels, underground wiring systems.
Most PVC plastic particles have a water absorption rate of less than 1%, so they are melted to form adhesives for the slots on the body of electric cars or become a coating to increase the life of the car against the impact of the external environment. Due to its superior dimensional stability, ability to provide a high-quality surface, and resistance to fading and discoloration, PVC is often chosen over other materials.
ABS plastic is chosen as the material for the production of electric vehicle doors for the following specific reasons:
First, the tensile strength of ABS ranges from 30 to 60 megapascals (MPa), ensuring structural integrity and load-bearing capacity. The door assembly must be strong not only to stabilize the vehicle body but also to ensure driver safety. This high tensile strength makes ABS an excellent choice for applications that require components to withstand mechanical stress and impact.
Second, ABS plastic is capable of absorbing impacts, vibrations, and shocks because the elastic elongation of the material ranges from 1.9 to 2.5 gigapascals (GPa). Although these are not very high parameters, they also contribute to the ability of ABS to resist breakage and fracture under dynamic loads.
First, electric car doors made from PET plastic ensure quality and safety. Because the tensile strength of the material reaches over 40MPa. In addition, their density is 1.38g/cm3 as well as the burning point is higher than 250 degrees Celsius, ensuring that electric car doors are durable and minimizing degradation or deformation.
Second, PET plastic is also adaptable to current popular production methods, they are considered not too difficult to shape and combine with plastic additives to increase core characteristics. Therefore, the production of electric car doors from PET plastic helps businesses save costs while still ensuring product standards.
Third, in terms of sustainability, PET is a highly recyclable material, which is important in the automotive industry as more and more people focus on sustainability and reducing the environmental impact of manufacturing. Next, manufacturers can freely create and sketch unique ideas for electric car windows thanks to the flexible and easily shaped properties of PET plastic. Furthermore, unlike metal that rusts when scratched, PET panels or plastic car door panels are easier to repair or replace when dented or scratched.
Like the above plastics, PC plastic is suitable for making electric car doors because of its impact resistance. Impressive parameters show that their tensile strength reaches the mark of 55 - 75MPa, Izod impact strength is in the range of 600 - 850J/m. Therefore, the material can ensure shape retention and minimize cracking, breakage or dents due to strong impacts.
Despite its stable hardness, PC plastic also ensures that the weight is not too heavy for the electric car door parts. The specific gravity of the material ranges from 1.18 - 1.20g/cm3. In addition, the temperature range of the material is from minus 100 degrees Celsius - 130 degrees Celsius. Therefore, PC plastic is not only a material for making doors but also contributes to the manufacture of other parts outside the car frame such as: Window glass, windshield, car frame, headlight lenses.
The flexibility of PC plastic is similar to PET plastic. Therefore, manufacturers can easily shape and mold each part of the car from the PC molten plastic mixture. In addition, the ability to withstand high temperatures is a feature that makes PC plastic ideal for electric car applications besides car doors. As mentioned above, 130 degrees Celsius is the highest temperature that PC plastic can withstand.
