Greatly motivated by the standard CO2 emission legislation, increasing worldwide customer awareness, and environment regulations, the present auto industry persists to make every effort in the direction of attaining greater fuel efficiency.
The urge for improved fuel efficiency has actually increased the hopes of the polymer industry. Punishments for excess CO2 emissions from cars have made sure that all car manufacturers utilize each and every material as a standard design adjustable to make sure that the overall vehicle weight is decreased, with absolutely no negotiation on performance and consumer safety.
As per the ICB stats in ICIS, a ten percent cutback in the overall vehicle weight will actually result in almost 5 to 7 percent fuel savings, provided that the power-train is also downscaled, or almost 3 to 4 percent fuel savings with no additional revisions to the standard engine specs.
The recent surveys conducted on the materials have clearly displayed that aluminum, AHSS (advanced high strength steel), and a few well-known plastic materials such as polyurethane (PU), polyamide (PA), and polypropylene (PP) have surfaced as favored choices, when it comes to light-weight vehicle designing.
The innate features of plastic materials have been the most important drivers that are encouraging the use of these materials in the vehicle designing. The major inherent features of the plastics that are influencing their usage in the vehicle fabrication processes include lower tolling expenses for huge volumes, light-weight, and the capability to be constructed as one complex constituent, thus completely removing the requirement for mechanical fasteners.
A standard passenger vehicle usually contains almost 8 percent of plastic content in its overall body weight, and in this regard, the European market stays at the first place by allowing a usage of up to 11 percent plastic content. Normally, car interior plastics make up almost 48 percent, while under-bonnet and exterior plastics accounting for around 14 percent and 27 percent respectively, of the total plastics that are utilized in a vehicle construction process. Cable and electrical materials will occupy the remaining eleven percent of the total plastics used.
Under-skin constituents usually provided great scopes, and appreciable penetration potential, especially in Latin America andAsia. On the other hand, in some of the mature vehicle markets including Europe andNorth America, plastics are finding their way into roads in the form of newer exterior and interior apps.
As per the latest estimation from Frost & Sullivan, demand for plastic materials in standard passenger cars is expected to rise up to almost 9.1 million tons internationally by 2017 model year from the present 5.5 million tons.
