Modern Car Bumpers Are Made of Plastic

Both front and rear bumpers in latest vehicles are generally comprised of plastic over a reinforcement bar made of fiberglass, aluminum, or steel. Car manufacturers design the bumper bar in a low speed to absorb energy. The formed thermoplastic or polypropylene foam is used instead of crushable bar or brackets. The main purpose, however, isn’t to serve as an energy absorber, but as a spacer on bumper cover and the bar. Bumpers became the standard component on all cars in 1925 and are available in the form of metal beams fixed to the rear and front side. Later, it evolved from complex engineered equipment, which became the integral part of the car in low-speed collisions. Modern car bumpers are made of plastic and are usually enjoyable, while providing benefits to both drivers and designers.

A majority of modern plastic bumpers are made of polyesters, polyamides, thermoplastic olefins (TPO), polyurethanes, or polypropylene, or blends of these with glass fibers for structural rigidity and strength. The use of plastic in bumper system gives engineers a great amount of liberty when it comes to designing a prototype vehicle or enhancing an existing car. Keeping both functional and aesthetic terms in mind, plastic can be styled in many ways without affecting the production cost much. The reinforcements involved in the process allow them to be as highly-resistant as metals, also being less expensive than metal equivalents. Like metal bumpers, it expands at the same pace under normal driving temperature and don’t need any special matches to preserve them in one position.

Moreover, some of the components used in making auto plastic bumpers can be recycled. It is the best way to reuse materials for a maker in a cost-effective way. In the recycling process, painted TPO scrap removes the cover from yard plastic to make new bumper fascia. The recycled TPO does the same work as original material, while reducing the overall material cost.

Improving the driver experience and personalizing the look of a car can be the greatest form of enjoyment for any car owner. A wide range of auto accessories are available in today’s market and modern plastic bumper is one of the best things to consider for improving your car. A specially made car bra acts as protector wraps around the car bumper to shield against insects, grit, flying stones, and other street debris, which can cause damage to dents or chips. These bumpers are the first line of defense from the grind and bump of the outside world and these are meant to absorb shock, offering an aerodynamic surface through air at high speed.

The plastic bumpers are chosen to the best over chrome plated steel due to the fact that they’ve been made from reinforced TPO. The chrome-plated steel bumpers are expensive and are quite heavy and can be easily dented. Thermoplastic materials are easy to create, acting as a cushion to dispel energy. It can be heated many times, without losing its ability or plasticity to be molded while hot. Most automakers are using thermoplastic olefins because of their energy absorbing qualities, low cost, and ease of production. Its outer shell has been made with number of thermoplastics, which are mounted on a metal frame, above the chassis of the car.  Beyond stability, geometry, and energy absorption, it protects the fenders and headlamps.
