Driving forward plastics solutions for chassis and body in white applications
The automotive chassis is roughly one third of the mass of vehicle and forms the structure where the interior, exterior, powertrain, and electronics finds mounting. It is the first defense in protecting the occupant and components protection. The incumbent materials are primarily metal based offering an opportunity to use composites to reduce weight and enhance performance (strength, energy management, NVH damping, etc.) with our expanding product portfolio.

Occupant and future powertrain protection
eMobility is the lead movement in the automotive industry to address our need to make our lives more sustainable. Due to the size and location of the batteries it is imperative to protect the passengers by limiting the intrusion into the battery compartment during an impact event. Continuous fiber systems using our polyurethane Elastocoat® offers the ability to create structures with the strength of steel at third of the mass with no concern of mixing with dissimilar materials. In addition to offering structure, BASF offers solution to manage kinetic energy for high deformation events with our Ultramid® in the form of foams or impact modified injection or extruded grades.

Noise and vibration management
eMobility brings additional challenges to noise and vibration abatement. Electric motors reduce vibration at lower frequencies but introduce new higher frequency noises due to the high rpm motors. BASF Ultramid® reduces sound and vibration transmission when replacing metallic engine suspension mounts due to the inherent damping characteristics of polymers. BASF Elastoflex® ultralight BIW NVH foam is used today to fill the cavities of the automotive body to absorb and block noise transmission to the automobile interior.

Lightweight body structure enhancement
To improve the performance of metal structures, BASF’s Thermoplastic Ultramid® and Ultradur® is used to reinforce the metal profiles by delaying the failure of metal structure leading to an increased peak load up to 300%. This can also be accomplished by filling the cavity with BASF Elastolit® D structural foam.

Detailed material information for chassis and body in white solutions
Polymer based solutions create an automobile chassis to manage the high out propulsion, to maximize occupant protection, reduce vehicle mass, and improve passenger comfort.
The emergence of eMobility brings new challenges to the chassis to provide mounting for the high torque eMotors, protect the passengers and high-density battery from intrusion during an accident, and minimize sound and vibration from these much higher frequency sources. BASF’s Polyurethanes Elastocoat®, Elastoflex® E, Elastoflex® W and Elastolit®; along with Engineered Plastics Ultramid®, Ultradur®, and Ultraform® provide solutions with a superior strength to weight ratio compared to metal, manage frontal and side impact events, while providing an environment which the passenger remains in peace.
