• A brief on automotive bumpers
• Innovative materials used in automotive bumpers
• Ultra-Poly's new bumper recycling program
• Eurorepar’s latest bodywork product line

Since their invention, automotive bumpers have evolved significantly from simple metal bars to sophisticated components designed for both safety and aesthetics. In modern vehicles, bumpers play an important role not only in protecting the vehicle but also in ensuring the safety of passengers and pedestrians. They act as a cushion, minimizing damage during low-speed accidents and providing the first line of defense against more severe impacts.

Understanding the intricacies of automotive bumpers

Automotive bumpers are protective structures installed at the front and rear of cars to absorb impact during collisions. They act as a buffer, minimizing damage to the car’s body and safeguarding occupants. Both bumpers of a vehicle offer comprehensive protection against collisions from various directions.

Initially, bumpers were primarily made of steel. They could not absorb impact effectively, which resulted in significant damage to collided cars. However, with technological advancement, modern bumpers evolved significantly, and metal bumpers were phased out because of improved fuel efficiency, and adherence to modern crash safety standards.

Now, they are constructed from materials such as plastic, fiberglass, or composite materials, allowing for better energy absorption during collisions. Additionally, modern cars are equipped with bumpers designed to adhere to stringent safety regulations while providing enhanced impact protection and aesthetic appeal.

Cutting-edge materials transforming automotive bumper performance

By eliminating the use of steel and aluminum, several automotive manufacturers have started using innovative materials to absorb impact effectively and remain relatively undamaged. They are emphasizing the use of innovative materials to enhance safety and protection of vehicles. At present, Polypropylene (PP) has emerged as a promising material that offers greater resistance to major impacts. It is a thermoplastic polymer that has unparalleled properties to absorb impacts, offering a suitable material for designing bumpers. It is widely used in vehicles to protect the chrome metal bumper.

On the other hand, solid polyurethrane is an elastomeric material of exceptional physical properties including toughness, flexibility, and resistance to abrasion and temperature. Other characteristics of this material include extremely high flex-life, high load-bearing capacity and outstanding resistance to weather, ozone, radiation, oil, gasoline and most solvents, ideal for designing bumpers in vehicles of various segments.

Moreover, acrylonitrile butadiene styrene is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene, providing a suitable alternative for bumper production. It is a rubbery substance that provides resilience even at low temperatures and gives the plastic a shiny, impervious surface. This material can be made to improve impact resistance, toughness, and heat resistance. These promising materials are expected to create wide possibilities in the automotive bumper industry.

Ultra-Poly's innovative bumper recycling program revolutionizing automotive sustainability

In August 2023, Ultra-Poly, a Pennsylvania-based plastics recycler collaborated with Autoneum North America Inc., a leading automotive supplier to launch an automotive bumper recycling program, which involves the collection and reprocessing of damaged bumpers into a new raw material. Through this collaboration, the companies aimed to develop a product that uses the recycled bumper material as a rigid backing substitute for a fibrous layer. This further helped to create a composite used in vibration and noise attenuation in a chassis component. The recycled bumper material is listed in the International Material Data System (IMDS). According to Kevin Cronin, Ultra-Poly vice president of sustainability and R&D, this groundbreaking program is going to advance the automotive industry closer to achieving the standards of a circular economy.

Eurorepar’s new bodywork product line featuring expert-approved bumpers

In April 2024, Eurorepar, multi-brand range of automobile products (spare parts, accessories, tyres, oils, consumables, etc.) from the Stellantis Group intended for servicing and repairing vehicles announced to extend its range of parts and introduce its new bodywork product line including bumpers. This new product range offers bumpers for Stellantis passenger cars and commercial vehicles brands. The bumpers designed by Eurorepar are carefully designed and have undergone numerous tests approved by experts at Stellantis to guarantee durability, aesthetic appearance and top-level security.

Summing up, automotive bumpers serve as essential safety features in modern vehicles, protecting vehicles and occupants from harm during collisions. With the growing demand for lightweight vehicles, plastic bumpers are expected to gain huge popularity in the coming years, offering a balance of durability, impact absorption, and aesthetic appeal.
