In 2017, sales of sports utility vehicles and off-road vehicles accounted for about one-third of global sales. Continued growth in demand for sport utility vehicles and off-road vehicles, coupled with rising global emission standards, has prompted many automakers to begin using lightweight thermoplastic rear door modules.

Compared with the corresponding steel modules, these recyclable rear door modules can reduce weight by 25% and have greater design freedom. For this, Magna can provide car manufacturers with relevant expertise.

“Magna ’s thermoplastic rear door module meets the growing demand of car manufacturers for products that help reduce vehicle weight, improve fuel economy, reduce CO2 emissions, extend the range of electric vehicles, and improve aerodynamics. “Grahame Burrow, general manager of Magna ’s exterior department, said,“ These rear door modules also provide greater design freedom, which means that our customers can better shape their own brand image. ”

Magna's thermoplastic rear door module:

It is necessary to add ultraviolet absorbers to agricultural films. The test proves that when the ultraviolet absorber is added in an amount of 0.2 parts. The film exposure time can be extended from three months to about one year (depending on the specific formulation design). Commonly used ultraviolet absorbers are benzophenones, benzotriazoles, triazines, and salicylates. .

There is only a narrow range of light waves in sunlight that has a degrading effect on polyvinyl chloride. The most harmful is the light wave with a wavelength of 3 ± 0 nm, which is the central band of ultraviolet light

In practice, it has been proved by application that under the condition of 0.3 parts, the absorption effect of the triazine ultraviolet absorber is much better than that of UV-9, which can be clearly seen from the spectral curve of the film in the ultraviolet region.

Magna started producing thermoplastic rear door for a high-end European car manufacturer in 1999, and then produced such rear door for more European car brands. In North America, the first thermoplastic rear door was used in the 2014 Nissan Rogue car. In 2018, the thermoplastic rear door was put into use in 2019 Jeep Cherokee and 2019 Acura RDX. Later in 2018, Magna will also launch two thermoplastic rear doors in China. In short, Magna has produced more than 3 million thermoplastic rear door modules worldwide. In addition to weight reduction and design freedom, Magna's system-wide assembly and delivery method also brings the following key advantages: reducing the complexity of the entire rear door module, reducing the investment cost of the mold and increasing the assembly plant's output.
